Earth's Processes

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by sediment deposition.

What is a constructive process in geology?

Back

A constructive process is a geological process that builds up Earth's surface, such as sediment deposition, volcanic activity, and mountain building.

Front

What is a destructive process in geology?

Back

A destructive process is a geological process that wears down or removes material from Earth's surface, such as erosion and weathering.

Front

What are the main causes of physical weathering?

Back

The main causes of physical weathering include temperature changes, freeze-thaw cycles, abrasion, and biological activity.

Front

What is the role of acid rain in weathering?

Back

Acid rain contributes to chemical weathering, not physical weathering, by dissolving minerals and altering rock structures.

Front

What is the Grand Canyon an example of?

Back

The Grand Canyon is an example of a destructive process, specifically erosion caused by the Colorado River.

Front

What is wind erosion?

Back

Wind erosion is the process by which wind removes and transports soil and rock particles, shaping the landscape.

Front

What is sediment deposition?

Back

Sediment deposition is the process by which sediments settle out of a transporting medium, such as water or air, and accumulate in a new location.

Front

How do rivers contribute to landform creation?

Back

Rivers contribute to landform creation through processes like erosion, sediment transport, and deposition, forming features like valleys, deltas, and floodplains.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals at their location, while erosion is the movement of those materials from one location to another.
