U3L1 Flashcard

Front

What is physical weathering?

Back

Breaking down rocks through mechanical processes like freezing, thawing, or abrasion.

Front

What processes are responsible for changes in a river's path over time?

Back

Erosion and deposition, as the river carries sediment away and deposits it, gradually reshaping the surrounding land.

Front

What is the name of the process that involves breaking down rocks without changing their composition?

Back

Physical Weathering.

Front

What happens to sediment when a river carrying it slows down or stops?

Back

The sediment is deposited as it settles to the bottom.

Front

How do water and gravity work together to erode materials?

Back

Water moves soil, sediment, and rock downhill, while gravity pulls the water and materials to lower elevations.

Front

What is erosion?

Back

The process of moving weathered materials from one location to another.

Front

What is deposition?

Back

The process where eroded materials settle in a new location.

Front

What is chemical weathering?

Back

Changes in rock composition through chemical reactions.

Front

What role does abrasion play in physical weathering?

Back

Abrasion is the process of scraping or wearing away rocks through friction.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those weathered materials.
