Weathering and Erosion Flashcard (level 2)

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

The process of moving weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is mass movement?

Back

The movement of soil and rock down a slope due to gravity, often triggered by factors like heavy rain or construction.

Front

What is abrasion?

Back

The process of wearing down rocks through friction and impact, often caused by water, wind, or ice.

Front

What is deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the risk of erosion by stabilizing the ground.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering, breaking down rocks through freezing and thawing or by dissolving minerals.

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.

Front

What is the significance of rounded rocks in rivers?

Back

Rounded rocks indicate they have been worn down by abrasion from flowing water over time.

Front

What is chemical weathering?

Back

The process of breaking down rocks through chemical reactions, often involving water and atmospheric gases.
