Question

What causes earthquakes? (1 point)
Pressure builds up in the molten rock beneath Earth's crust and causes it to shake.
• Blocks of crust slide against one another, often at plate boundaries.
• Sudden motions in Earth's mantle cause the crust to shift.
• Tectonic plates break apart into smaller plates, and the crumbling causes shaking.

Answer 1

Tectonic plates breaking apart into smaller plates and the resulting shaking is the main cause of earthquakes.
