Weathering
The process where rocks break into smaller pieces.
What is weathering?
The process where particles of rocks are picked up and moved.
The process where particles of rocks are placed somewhere else as sediments.
What is deposition?
Horizontal strata of soil.
What are horizons?
Large masses of dense ice that flows under the influence of gravity.
What are glaciers?
Changes the composition of the rocks.
What is chemical weathering?
The very slow downhill motion of soil.
What is creep?
Narrow bodies of water that flow in a channel or streambed.
What are streams?
Decayed organic matter.
What is humus?
All deposits of sediments from glaciers.
What is glacial drift?
Does not change the composition of rocks.
What is mechanical weathering?
When rocks and soil move by gravity alone on sloped land.
What is mass wasting?
Rough water that can carry sediments.
What is turbulence?
A layered formation at the surface of the earth made of inorganic earth materials combined with organic nutrients.
What is soil?
Small lake that form in cirques.
The mechanical action of plants and animals on rocks.
What is biological weathering?
Soupy mixtures of loose earth debris and water.
What are mudflows?
What is deflation?
A scientist who studies soil, soil formation, and erosion.
What is a pedologist?
Broad ice sheets that cover most of a continent.
What are continental glaciers?
When rocks separate into thin layers or slabs.
Rapid mass wasting of earth materials downhill.
What is a landslide?
When large particles of rocks hop repeatedly over the stream bottom.
What is saltation?
Rests on top of the bedrock and consists of broken and weathered pieces of bedrock.
What is C-horizon?
The glaciated valley that reaches the sea.
What are Fjords?
