Earthquakes usually occur at boundary of crustal plates.
Option A
Explanation:
- Crustal plates, also known as tectonic plates, form the outer layer of the Earth. There are seven major plates and many smaller plates.
- Tectonic plates contain both the Earth's crust and uppermost part of the mantle.
- Over time, the surface of the earth cooled and hardened.
- Cracks formed in the hardened surface, creating huge plates of rock.
- These, plates will carry the "continents" and make of the ocean floor, floating in the islands on the "hot, taffylike rock below".
