Definitions:

Plate Boundaries

Plate boundaries are the edges where two or more of Earth's tectonic plates meet, categorized into three types: divergent, convergent, and transform, each characterized by specific geological activities and processes.

Deep Earthquakes

Seismic events that occur at depths greater than 70 kilometers below the Earth's surface, typically associated with subduction zones.

Wave Amplitude

The height between the trough and the crest of a wave, including ocean waves and seismic waves.

Continental Collisions

The process where two continental plates collide, often leading to mountain building.
