Weathering/Erosion/Deposition

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion carries the broken pieces away.

Front

What causes acid rain?

Back

Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which then mix with water vapor and fall as precipitation.

Front

What is oxidation in the context of weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, often leading to rusting in iron-rich rocks.

Front

What is exfoliation?

Back

Exfoliation is a type of mechanical weathering where layers of rock peel away due to temperature changes.

Front

What is abrasion?

Back

Abrasion is the process of wearing down surfaces through friction, often caused by wind or water carrying particles.

Front

How do weathering and erosion affect river pebbles?

Back

Weathering and erosion smooth and round river pebbles as they are transported and collide with other rocks.
