FLASHCARD QUESTION

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks and minerals into smaller pieces without changing their chemical composition. It can be caused by factors like temperature changes, freeze-thaw cycles, and abrasion.

FLASHCARD QUESTION

Front

What is chemical weathering?

Back

Chemical weathering involves changes in the minerals of rocks that break down bonds and alter the chemical makeup of the rock. This can occur through processes like hydrolysis, oxidation, and carbonation.

FLASHCARD QUESTION

Front

What is erosion?

Back

Erosion is the process by which soil, rock, and other surface materials are worn away and transported from one location to another, often by wind, water, or ice.

4.

FLASHCARD QUESTION

Front

What is deposition?

Back

Deposition is the process in which sediments, soil, and rocks are added to a landform, creating new geological features such as beaches, deltas, and sandbars.

5.

FLASHCARD QUESTION

Front

What causes physical weathering?

Back

Physical weathering can be caused by factors such as temperature fluctuations, freeze-thaw cycles, abrasion from wind or water, and biological activity like burrowing.

6.

FLASHCARD QUESTION

Front

What is oxidation in the context of weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, particularly those containing iron, leading to rust formation and weakening of the rock.

7.

FLASHCARD QUESTION

Front

What is hydrolysis?

Back

Hydrolysis is a chemical weathering process where water reacts with minerals to form new minerals and soluble salts, often leading to the breakdown of feldspar into clay.
