What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to natural forces such as wind, water, and ice.

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 materials carried by wind, water, or ice are dropped in a new location, forming new landforms.

Front

What are nonrenewable resources?

Back

Nonrenewable resources are natural resources that take millions of years to form and cannot be replaced quickly, such as fossil fuels.

Front

What is retention in terms of water?

Back

Retention refers to the ability of soil to hold water, which is important for plant growth.

Front

What causes weathering?

Back

Weathering can be caused by various factors including temperature changes, water, ice, and chemical reactions.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to a new location.

Front

How does acid rain affect rocks?

Back

Acid rain can chemically weather rocks, breaking them down more quickly than normal rain.

Front

What role do waves play in weathering?

Back

Waves hitting rocks can cause physical weathering by breaking down the rock over time.

Front

What is an example of physical weathering?

Back

An example of physical weathering is ice cracking rocks as it freezes and expands.
