Oh, hello friends! Are you wondering what this is? Well, it's the molten lava that comes out from a volcano Come, let me tell you what a volcano is. Zoooom in! I am sure you've seen mountains that open up and blurt out thick molten semi-solid like substance? Well, that's called a volcano! Let’s learn more about it. A volcano is a vent or 'chimney' that connects Magma from within the Earth’s crust to the Earth's surface. The liquid rock is called Magma when it is under the earth's surface and Lava after it comes out. So how does a volcano erupt? The molten rock stored in the magma chamber rises through the crater pipe pockets. As it travels up the main vent, gases expand and water becomes steam, creating pressure. When the pressure can no longer be contained the volcano erupts through the crater and secondary side vents. Common volcanic gases include water vapour, carbon dioxide, sulfur dioxide, hydrogen chloride, hydrogen fluoride and hydrogen sulfide. Popular belief is that Volcanoes are large cone-shaped mountains but that's not true. There are many more types of volcanoes, such as - wide plateaus, fissure vents and bulging dome shapes. There are also volcanoes found on the ocean floor and even under icecaps such as those found in Iceland. The word volcano originally comes from the name of the Roman god of fire Vulcan The tallest volcano in the Solar System isn’t on Earth at all but on Mars.
