What is volcanic etruption? |
|
Answer» A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that ALLOWS hot lava, volcanic ash, and gases to escape from a MAGMA chamber below the surface. Earth's volcanoes occur because its crust is BROKEN into 17 major, rigid tectonic plates that float on a HOTTER, SOFTER layer in its mantle. |
