Front

What is mass wasting?

Back

The downhill movement of loose rocks and soil caused by gravity.

Front

Which scientists believe glaciers helped shape Earth's features?

Back

Both old-earth and young-earth scientists.

Front

What is carbonation?

Back

The process in which carbon dioxide dissolves in water to create carbonic acid.

Front

True or False: Material eroded by rivers is usually lost in the ocean.

Back

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is till?

Back

Unsorted material deposited by a glacier, consisting of a mixture of clay, silt, sand, gravel, and boulders.

Front

What is deflation?

Back

The removal of loose, fine-grained particles from the ground by wind, leading to the lowering of the land surface.

Front

What is a glacier?

Back

A large mass of ice that moves slowly over land, shaping the landscape through erosion and deposition.
