Answer» 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. Explanation: The main parts of a volcano include the magma chamber, CONDUITS, vents, craters and slopes. There are three types of volcanoes: cinder cones, stratovolcanoes and shield volcanoes. |
