Weathering and Erosion Env Sci Flashcard BWHS

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces without changing their chemical composition.

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 the primary agent of erosion?

Back

Moving water is the primary agent of erosion, shaping landscapes through rivers, streams, and rainfall.

Front

What is mechanical weathering?

Back

A type of weathering that physically breaks rocks into smaller pieces without altering their chemical composition.

Front

What is chemical weathering?

Back

A type of weathering that involves the chemical alteration of minerals in rocks, changing their composition.

Front

What role do glaciers play in erosion?

Back

Glaciers erode the landscape by scraping and grinding rocks as they move, transporting debris.

Front

How does wind contribute to erosion?

Back

Wind can erode surfaces by carrying away loose particles, especially in arid environments.

Front

What is deposition?

Back

The process by which eroded materials are dropped off in a new location, forming new landforms.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials.

Front

What is the significance of soil horizons?

Back

Soil horizons are layers of soil that differ in composition, texture, and color, important for understanding soil health.
