Weathering

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process of moving weathered material from one location to another, often by wind, water, or ice.

Front

What is the main factor that determines the rate of weathering in permeable rocks?

Back

Surface area.

Front

What is acid rain?

Back

Acid rain is a type of chemical weathering that occurs when sulfur, carbon, and nitrogen compounds in the air react with water vapor.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of weathered material.

Front

What type of weathering is rusting?

Back

Rusting is a type of chemical weathering.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering and chemical weathering.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of 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 an example of mechanical weathering?

Back

An example of mechanical weathering is freeze-thaw action, where water seeps into cracks, freezes, and expands, breaking the rock apart.
