Volcano

Hi my name is Taki and I will telling you about how volcanoes explodes.

Earth has three layers, the first layer is called the  core which is shaped like a ball.The ball is so big and this is how hot it is 5430c.The second layer which is mantle is made out from hot,soft rocks.The mantle also contains pockets of  liquid rock and gases called magma.The magma can come to the top of the crust when it is soft.The top layer is the coldest,rocky crust,which supports homes on earth.When the magma finds are weak spot in the crust it come straight  into the earth.
