11、nderstand why volcanic eruptions happen，it is necessary to know some things about how the Earth is made.The part of the Earth we live on is an 18milethick layer of solid rock called the crust.Beneath the crust is a layer called the mantle(地幔)，it is hot enough to melt some of the rock，creating magma(
12、岩浆)When the magma finds cracks in the Earths crust，it rises up.Gas bubbles (气泡) inside the magma grow bigger and try to escape as the molten rock gets closer to the Earths surface.When the gas bubbles cant be held back any longer，the volcano erupts.Imagine shaking a soda bottle until the gas inside
13、blows the cap off，and you can understand something of how a volcano erupts.If the magma is runny，and the gas can escape easily，the eruption is gentle.But if the magma is thick，the gas has to build up more pressure to escape.Then the eruption is explosive.When a volcano erupts，the molten rock that fl
14、ows from it is called lava.The lava may run for some distance，or it may pile up near the volcano，making the mountain larger.During an explosive eruption，pieces of rock are thrown from the volcano.Scientists call these pyroclasts (火山碎屑)The smallest pyroclasts are called ash.Ash is often thrown into t
