Definitions:

Joints

Innate cracks or splits in rock formations that occur without any shift, typically due to how the rock reacts to pressure.

Mid-Ocean Ridges

Underwater mountain systems formed by plate tectonics, consisting of various mountains linked in chains.

Contact Metamorphism

Contact metamorphism occurs when rocks are heated to high temperatures and sometimes subjected to increased pressures due to the close proximity of magma or lava, without melting the rock completely.

Normal Faults

A type of fault where the hanging wall moves downward relative to the footwall, typically a result of extensional forces pulling the crust apart.
