Earthquakes and Volcanoes

The Earth’s crust is in constant motion, and as it moves, blocks of the Earth collide or slip past each other. This results in an Earthquake. Earthquakes are related to cracks in the crust called faults. A volcano is a rupture on the crust of the Earth that allows hot lava, volcanic ash, and gases to escape from below the surface. The hot molten rock deep below Earth’s surface is called magma and it rises upward.
