Question

open - ended questions: answer the following questions in complete sentences. explain how plate tectonics contribute to the occurrence of earthquakes.

Explanation:

The Earth's outer layer is split into rigid tectonic plates that move slowly over the mantle. When these plates interact at their boundaries—such as colliding, sliding past each other, or pulling apart—friction often prevents them from moving smoothly. This builds up elastic strain in the surrounding rock over time. When the strain becomes too great to be contained, it is suddenly released as seismic energy, which travels through the Earth as vibrations, causing an earthquake. Most earthquakes occur along these plate boundary zones.

Answer:

Tectonic plates are rigid sections of Earth's outer layer that move over the mantle. At plate boundaries, friction between plates stops smooth movement, causing elastic strain to build up in surrounding rock. When this strain exceeds the rock's strength, it is suddenly released as seismic energy, which propagates through the Earth as vibrations, resulting in an earthquake. The vast majority of earthquakes take place along these active plate interaction zones.
