S6E5 Weathering Erosion Deposition 2023

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 leading to the formation of new minerals.

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 water, wind, 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 causes weathering of tombstones over time?

Back

The weathering of tombstones is primarily caused by environmental factors such as wind, rain, and temperature changes that physically and chemically break down the stone.

Front

How do plants contribute to mechanical weathering?

Back

Plants contribute to mechanical weathering through their roots, which can grow into cracks in rocks, causing them to break apart.

Front

What role does flowing water play in erosion?

Back

Flowing water is a major agent of erosion, as it can carry away soil and rock particles, reshaping landscapes over time.

Front

What is a large-scale geoscience event?

Back

A large-scale geoscience event refers to significant geological processes, such as plate tectonics forming mountain ranges or volcanic eruptions.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one place to another.

Front

What are some examples of mechanical weathering?

Back

Examples of mechanical weathering include freeze-thaw cycles, abrasion from wind or water, and root expansion.
