Definitions:

S-Waves

Secondary or shear waves in seismology, a type of elastic wave that shakes the ground perpendicular to the direction of wave propagation and only travels through solids.

Continental Rifting

The process by which the Earth's crust stretches, breaks, and eventually forms a new ocean basin, often associated with divergent plate boundaries.

Transform Faults

A type of fault where two tectonic plates slide past each other horizontally, commonly found at the boundaries of tectonic plates.

Intrusions

Geological features formed when magma cools and solidifies before reaching the surface, creating bodies of igneous rock.
