2021 EH Investigation 2 Flashcard

Front

What is deposition?

Back

Deposition is the process by which sediments settle out of a fluid, such as water or air, and accumulate in a new location, forming features like deltas.

Front

Which rock fizzes when acid is added?

Back

Limestone fizzes when acid is added due to the presence of calcium carbonate, which reacts with the acid.

Front

What is chemical weathering?

Back

Chemical weathering is a type of weathering that involves the breakdown of rocks through chemical reactions with air or water.

Front

What is an example of water eroding rock?

Back

Creating a canyon is a prime example of water eroding rock over time.

Front

How does wind erode rocks?

Back

Wind can erode rocks by blowing away topsoil and small particles, gradually wearing down larger rocks.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

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 water, wind, or ice.

Front

What is the role of frost wedging in weathering?

Back

Frost wedging is a physical weathering process where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is root wedging?

Back

Root wedging is a physical weathering process where plant roots grow into cracks in rocks, exerting pressure and causing the rocks to fracture.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process of wearing down rocks through friction and impact, often caused by wind, water, or ice carrying particles.
