The geologic principle that the same geologic processes that operate today operated in the past to change Earth’s surface.

The process by which water, ice, wind, or gravity moves weathered particles of rock and soil.

Mechanical weathering

The type of weathering in which rock is physically broken into smaller pieces.

The process that breaks down rock through chemical changes.

the loose, weather material on Earth’s surface in which plants can grow.

Dark colored organic material in soil.

Small, solid pieces of material that come from rocks or the remains of organisms; Earth materials deposited by erosion.

Process in which sediment is laid down in new locations.

Any one of several processes by which gravity moves sediment downhill.

The process by which wind removes surface materials.

A wind-formed deposit made of fine particles of clay and silt.

Water that flows over the ground surface rather than soaking into the ground.

A channel through which water is continually flowing downhill.

A stream or river that flows into a larger river.

The flat, wide area of land along a river.

A landform made of sediment that is deposited where a river flows into an ocean or a lake.

A wide, sloping deposit of sediment formed where a stream leaves a mountain range.

Water that fills the cracks and spaced underground solid and rock layers.

Any large mass of ice that moves slowly over land.

A glacier that covers much of a continent or large island.

Time in Earth’s history during which glaciers covered large parts of the surface.

A long, narrow glacier that forms when snow and ice build up in a mountain valley.

The process by which a glacier picks up rocks as it flows over the land.

The sediments deposited directly by a glacier.

The movement of water and sediment down a beach caused by waves coming in to shore at an angle.
