[Music] what are you making little kitty for that you'll need more than just clay bye hmm that's an excellent question hey friends in today's episode let us see the process behind the creation of a beloved planet and answer a crucial question how did the earth form zoom in planet earth a giant mass of water and mud revolving in space and the only known home sweet home formed just for us as it gives us food to eat water to drink and aid to breathe making it a perfect breeding ground for life to evolve but have you ever wondered how did this giant planet come into existence in the first place i'm sure you did so let me tell you this astonishing story of the earth's formation well it all began a long time ago which is about 15 billion years ago when the whole universe was inside a tiny bubble called the cosmic egg then about 13.8 billion years ago the little bald bubble began heating up and generating energy until it finally exploded with a bag today we call this massive explosion the big bang you can check a video on the same the link is in the description then about 4.5 billion years ago when the universe began to cool down a bit and settled into its current layout everything started to spin forming mighty wind and gravity and over time one such gravitational force from the remnant of a dead star started pulling the giant dirty gas cloud this cloud got denser and denser in its center and formed an accretion disk then in the next 10 to 20 million years other small particles of dust rock and gas started sticking together creating larger objects until it became a sphere and large enough to be called a planet by today's standard and young earth was formed at this point the earth's surface temperature was a burning mess with seas of lava and a poisonous atmosphere not only that various comets asteroids and other cosmic elements constantly attacked it from all sides making it boil more and more but soon things took a dramatic turn and the cosmic attack reduced and so as the temperature of the earth cooled down water from the inside of the earth rose to the surface formed steam and rained back on the ground to form oceans even other meteors brought more water to our land in the form of ice so gradually the earth cooled down and the surface formed a thin crust meanwhile the volcanoes on the ocean's bed blew magma to the top which eventually cooled down to form volcanic islands that joined together to create a single giant continent called pangaea and inside the earth the hot rock continued to move around moving the crust below and breaking it apart through a process called plate tectonics we have a separate video dedicated wholly to this topic please check the link below and as the earth's crust moved around pangaea broke apart and its pieces drifted away to create the continents we see today and modern earth took its form a place we all can proudly call home trip your time did you know april 22nd every year is observed as earth day yes it was first organized in 1970 to promote ecology and raise awareness of the growing problems of air water and soil pollution so please do your bit and share this video with friends and family hope you learned something new in today's episode until next time it's me dr binox zooming out [Music] ah never mind [Music] oh no little kitty the earth isn't flat from the top it's all around round and round plus a chainsaw isn't a thing to play with phew now let me tell you about the shape of our earth hey friends we all know um i mean apart from the flat earth community we all know that the world is round but have you ever wondered why well in today's episode let us go around this question to find the answer zoom in [Music] if you look at our solar system you will see planets made of rocks gas with rings without them some are small in size while others are big one factor common in all is that they are round shape yes but the vital question is why is that and what is the reason behind their round shape before we dwell on their shape let us see when do we call a celestial body a planet well according to iau for a celestial body to be called a planet it needs to fulfill three essential criteria first the object should revolve around the sun second the object should be spherical and thirdly the area around its orbit should be clear and should not have any equivalent or a bigger celestial body meaning with the help of its gravity the planet should clear asteroids and dwarf planets out of its way [Music] so the point number two clearly states that the planet needs to be round or spherical but we don't see any other shape hovering in space in the first place isn't it friends most things we see are round or pretty close to it including asteroids so what's going on here well the answer is gravity yes earth and other planets are round because of the force of gravity that pulls equally from all sides gravity pulls from the center to the edges like the spokes of a bicycle wheel this makes the overall shape of a planet round which is a three-dimensional circle but planets are not exactly round but roughly spherical or oblate spheroids yes if noticed carefully you will see that the equatorial diameter of the earth is about 43 kilometers larger than the polar diameter this is because just like a spinning top our earth spins on its axis with a speed of 1674.4 kilometers per hour and this much velocity causes the planet to bulge near the equator due to centrifugal force as things near it tend to move away like mud flying off a tire and it's not just the earth but satin bulges the most of all the planets in our solar system yes if you compare the diameter from pole to pole to the diameter along the equator it's not the same satin is 10.7 percent thicker around the middle while jupiter is 6.9 percent thicker around the middle so instead of being round like marbles they are like basketballs squished down while someone sits on them trim your time did you know earth and mars are small and don't spin around as fast as the gas giants like jupiter saturn uranus and neptune also jupiter is known to be the fastest spinning planet in our solar system hope you learned something new in today's episode until next time it's me dr binox zooming out [Music] never mind ah there is nothing more magical than seeing the sun go down on the dusky horizon it's not the sun that goes anywhere during the dawn and sunset but it's us who move little kitty kitty's standing still yes little kitty it may appear like that and although we might not feel it our planet is continuously rotating and revolving on its axes hey friends so in today's episode let us debunk the mystery behind our beloved sun's hiding spot by learning about our earth's rotational and revolution movements zoom in so what are earth's rotation and revolution well here is a gorgeous illustration of our planet earth now imagine a line passing through its center of mass this imaginary line is called the axis and our planet spins around on this invisible line just like a top and the circular movement of an object spinning around its axis is called the rotation yes my dear friends and due to this rotational quality of our planet earth we witness day and night and how is that well it is because different parts of the planet are facing towards the sun or away from it yes my dear friends when you are located on the side where you can see the sun and its light and heat can reach you it's day time and when the earth spins to take you away from the sight of the sun where its light and heat can't reach you anymore it's night time and it takes 24 hours for the earth to turn all the way round to make a single day i know you guys must be thinking that if the rotation of the earth makes a day then what makes a year and the answer to this question is the revolution let me explain you see although the earth is rotating on its axis at the same time it also revolves on orbits around the sun which is called revolution and one full orbit all the way around the sun is one revolution and the earth takes 365 days or precisely 365.24 days to complete a revolution that makes up a whole year but don't get confused with the similarities of the words notation and revolution my dear friends in astronomy the word rotation is used to mean the movement around the axis which creates the day and night on earth while revolution is used when one body moves around another that makes a year in the case of a planet earth [Music] but here is a twist and that twist is in the axis as the earth is not sitting with a straight posture but its axis is actually a little tilted yes ions ago when an object the size of mars crashed into the newly formed planet earth it knocked a planet over and left it tilted at an angle and this slight tilt made one part of the earth lean towards the sun while the other part of it is leaning away and there is a great significance to this tilt my dear friends yes due to this angle the solar energy reaching different parts of our planet is not constant but varies during the year as at a particular time the northern hemisphere is leaning towards the sun while the southern is leaning away and at other times the southern hemisphere tilts towards the sun whereas the northern hemisphere leans away and this is why we have different seasons and why the seasons are opposite in the northern and southern hemispheres yes the part of the earth leaning towards the sun causes summer in that region and the days are long while the part leaning away experiences cold climate with shorter days so here we go friends now you know the difference between earth's rotation and revolution and why they are essential to make your world go round and round trip your time did you know the angle made by the axis of the earth which is an imaginary line with the orbital plane is 66 degrees also it is said that humans have made a moderate change in the earth's rotation period by several microseconds by accumulating vast reservoirs with trillions of tons of water [Music] hope you learned something new in today's episode until next time it's me dr binox zooming out [Music] [Music] oh never mind hello friends the best part of a pizza is its crust [Music] yummy just like this pizza the earth too has a crust but with no cheese in it so let's learn something about the structure of the earth today it consists of the crust mantle and core zoom in this is the earth's crust it consists of all kinds of rocks soil and everything you see above the earth's surface you will be surprised to know that the crust that is the land on which we walk is almost three times thicker than the crust under the oceans and it extends to about 25 miles the earth's crust floats on this layer which is called the mantle it is made of thick solid rocky substance and amounts to about 85 percent of the total mass of earth the first 50 miles of the mantle consists of very hard rigid rocks the next 150 miles are made up of super hot solid rocks below that for the next several hundred miles the earth's mantle is believed to be made up of very solid and sturdy rock materials the mantle is about 1 800 miles thick and by far the largest layer of earth the earth's outer co is made up of super hot liquid molten substance called lava [Music] this lava is believed to be made of iron and nickel it extends to a depth of 3000 miles beneath the earth's surface and finally we have reached earth's inner core the inner core extends another 900 miles towards the center of the earth it is believed that this inner core is a solid ball made of iron and nickel trim your time the crust occupies less than one percent of earth's volume the inuko is the hottest part of the earth and it is as hot as the surface of the sun surprising isn't it looks like it's time for me to zoom out before i get baked in this heat tune in next time for more fun facts [Music] what doctor painting the highest landform in the world little kitty yes little kitty hey friends in today's episode let me take you around the globe to witness the natural beauty our earth is blessed with known as the landforms and briefly explore the exciting formation process with stunning graphics from our creative team zoom in so what are the landforms of the earth just like all living beings have certain physical features that distinguish them from each other similarly the planet earth is made up of various unique features and characteristics we call landforms yes my friends the landform is the natural geographical of physical features of the earth that are classified into various types such as mountains hills valleys plateaus planes etc but before we shed some light on these types of landforms let us briefly examine the process leading to the formation of these features first comes the external process in which external factors such as wind and brain shapes the earth's surface by erosion and deposition yes erosion is a process in which sediments get deposited in a different location whereas sediments are the materials on the earth's surface such as soil and rocks next comes the internal process and as the name suggests it is the process that occurs inside the earth's surface such as plate tectonics and volcano eruptions these occur because of the extreme heat in the earth's core causing the molten rock in the mantle layer to move as a result causing uneven movement on the surface these layers are either uplifting or sinking forming different types of landforms that can be categorized into mountains plateaus and plains so let us explore these major types of landforms starting from the mighty mountains mountains are landforms higher and steeper than the surrounding areas in general the mountains are higher than 200 feet and divided into three categories fold block and volcanic yes when two tectonic plates collide and the edges of these plates fold because of the tremendous force between them it creates the fold mountains on the other hand the block mountains form when large areas are broken and displaced vertically these large areas of rock sometimes stretching across hundreds of kilometers are created by tectonic and localized stresses in the earth's crust and the third type of mountains are the volcanic mountains that are formed due to the magna flowing up from the mantle to the crust of the earth next comes the planes most of the earth's surface consists of low and high planes that are flat or the low relief areas on the surface of the earth these are the most fertile region of the planet and are the most suitable for human habitation and agriculture activities like farming and poultry it might be formed as a result of the sedimentation of eroded soil from the top of the hills and mountains or due to flowing lava deposited by the agents of wind water and ice now let us look at the landform we call plateaus a plateau is a flat elevated landform that rises sharply above the surrounding area on at least one side plateaus occur on every continent and take up a third of the earth's land and are divided into two categories dissected plateaus and volcanic plateaus a dissected plateau forms due to the upward movement in the earth's crust caused by the slow collision of tectonic plates whereas a volcanic plateau is formed by numerous small volcanic eruptions that slowly build up over time creating a plateau from the resulting lava flows and the fourth major type of landform is the ecological landscape known as the deserts it is a dry piece of land with little or no vegetation due to lack of rainfall in deserts the atmospheric air is arid and the daytime temperature is high the process by which fertile land becomes desert is called desertification you won't believe but human activities are a primary cause of desertification yes these activities include overgrazing of livestock deforestation over cultivation of farmland and poor irrigation practices overgrazing and deforestation remove plants that anchor the soil as a result wind and water erode the nutrient-rich top soil also hooves from feeding livestock compact the soil preventing it from absorbing water and fertilizers trim your time did you know the largest plateau in the world is the tibetan plateau located in central asia yes it stretches through the countries of tibet china and india and occupies an area of 2.5 million square kilometers also landforms can exist underwater in the form of mountain ranges and basins under the sea the mariana trench the deepest landform on earth is in the south pacific ocean hope you learned something new in today's episode until next time it's me dr bynox zooming out and the painting is done [Music] ah never mind hey kitty look a 17 year old intern at nasa has discovered a new earth-like planet isn't that brilliant i understand your curiosity kitty but one day we might be able to settle on a different planet but it's possible only if the new world has all the four major domains of earth present on it it's domains kitty hey friends it is rightly said that heaven is under our feet and over our heads but no wonder we fail to acknowledge it so in today's episode let me tell you about those four major domains of the earth that make our earth indeed a heaven zoom in so what are the four domains of earth the massive universe formed millions of years ago has infinite undiscovered spaces trillions of stars millions of galaxies and the nine planets in our solar system but the universe blessed planet earth with living beings and to make life possible three different components meet so humans can survive and thrive these are the elements of land water and air these are nothing but the domains of the earth namely the lithosphere hydrosphere and atmosphere which give rise to the biosphere let's have a good look at each of them starting with the lithosphere and to know about it let's speak a little beneath the earth's surface as you can see it is made up of various layers out of which the crust and the upper layer of the mantle make the lithosphere which is basically the solid portion of the earth the lithosphere is further divided into two parts the continental crust which is the thick part of the earth's crust which forms the large land masses and the oceanic crust that could be found deep under the ocean and seas which are denser than the continental crust now let us move further to learn about the hydrosphere [Music] you see although the earth seems hot and burning from inside but when you look at it from space you'll see one soothing cool planet due to its blue shade as around 71 percent of the earth's surface is covered by water and this water covered area is called the hydrosphere this 71 of the water is found in three different forms that is water located in a liquid state into the water bodies such as oceans seas lakes ponds etc in a solid state such as ice and gaseous state such as water vapor but always remember that out of the 71 of available water only 2.5 is consumable by humans so it is advisable that you consume water wisely and do not waste or contaminate it now let us move further and look at the sky i know you feel that the area between the surface of the earth and space is a vacuum or there is nothing in between but let me inform you that a lot is happening there as it is covered with a set of layers of gases we call the atmosphere that surrounds the earth this invisible shield of gas performs various duties like keeping us warm providing the oxygen and it is where the weather changes the atmosphere is further composed of different layers and each layer has its prominence the first layer is the troposphere the lowest layer of atmosphere that ranges up to five to nine miles above the earth's surface and is denser than other layers the troposphere is where all of earth's weather occurs and contains approximately eighty percent of the total mass of the atmosphere now as we move ahead up to 31 miles from the earth's surface we enter the stratosphere this vital layer absorbs harmful uv rays coming from the sun towards the earth with the help of the ozone layer present in it the next layer is mesosphere where meteors rushing with a high speed gets burnt up and after that comes the thermosphere where the solar radiations are absorbed and you can witness the aurora in the same layer and the last layer is exosphere which meets space now coming back to the fourth domain of earth that brings all the elements such as land water and air together is our last sphere the biosphere the biosphere represents every part of earth where living organisms are found that could be commonly divided into two main parts the plant kingdom and the animal kingdom this fear ranges from the vast sky to the base of the enormous water bodies such as oceans it is believed to be formed millions of years ago where the first living organism to be created was bacteria so here we go friends these are the four domains of the earth we need to survive and thrive on this vast universe and the earth is the only planet to be blessed with it so cherish it nourish it and make sure not to do anything to perish it because this is the only home we have our beloved planet earth trip your time did you know scientists claim that the earth is approximately 3.7 billion years old which also makes the biosphere to be almost the same age also researchers say that the depth of the biosphere is complicated to measure as there are fish known to be living as deep as 8 372 meters in the puerto rico trench hope you learned something new in today's episode until next time it's me dr bynox zooming out [Music] ah never mind
