The Process in which rock is broken down by changes in it's chemical makeup.

The transfer of thermal energy by the circulation or movement of a liquid or gas.

A tectonic plate where two plates collide, come together, or crash into each other

Process in which sediment is laid down or settling in new locations.

Shaking and vibration at the surface of the Earth resulting from underground movement along a fault plane from volcanic activity.

The boundary between two tectonic plates that are moving away from each other.

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.

(Geology) A crack in the Earth's crust resulting from the displacement of one side with respect to the other

A slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles

Liquid magma that reaches the surface; also the rock formed when liquid lava hardens.

A rigid layer made up of the uppermost part of the mantle and the crust,

Molten rock beneath the earth's surface.

The downhill movement of a large mass of rocks or soil due to gravity.

An undersea mountain chain where new ocean floor is produced; a divergent plate boundary.

Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.

A theory stating that the earth's surface is broken into plates or large rigid places that move.

The material formed from rocks broken down by weathering.

One plate going under another plate.

A plate boundary where two plates move past each other in opposite directions.

A vent or fissure in the Earth's surface through which magma and gasses are expelled.

The chemical and physical processes that break down rock at Earth's Surface.
