Weathering, Erosion, and Deposition

Front

What is weathering?

Back

The breaking down of rocks on Earth due to various physical, chemical, or biological processes.

Front

What is erosion?

Back

The carrying away of sediment and soil by wind, water, or ice.

Front

What is deposition?

Back

The process by which sediment settles out of the transporting medium, such as water or wind.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The breakdown of rocks through chemical reactions, altering their mineral composition.

Front

What is an example of mechanical weathering?

Back

Frost wedging, where water seeps into cracks, freezes, and expands, breaking the rock apart.

Front

What is an example of chemical weathering?

Back

Acid rain reacting with limestone, causing it to dissolve.

Front

How do ocean waves contribute to weathering?

Back

Ocean waves cause mechanical weathering by physically breaking down rocks and soil along the shore.

Front

What role does vegetation play in weathering?

Back

Plant roots can grow into cracks in rocks, causing mechanical weathering as they expand.

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.
