Final answer:
Most earthquakes occur along the edges of tectonic plates, which are large pieces of Earth's crust. These plate boundaries can be found in the ocean, like the Pacific Ring of Fire, and on land, such as the San Andreas Fault.
Step-by-step explanation:
Most earthquakes occur along the edges of tectonic plates. Tectonic plates are large pieces of Earth's crust that fit together like a jigsaw puzzle. When these plates move, they can create stress and pressure on the rocks surrounding them. When this stress becomes too great, it causes the rocks to break, resulting in an earthquake.
These plate boundaries are generally found in the ocean, such as the Pacific Ring of Fire, where several tectonic plates meet, and also on land, such as the San Andreas Fault in California. Therefore, earthquakes can occur both on land and in the ocean.
