Q2 Benchmark Exam Practice 2

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What causes valleys to form?

Back

Valleys are often formed by erosion from rivers or glaciers.

Front

How do rivers shape the Earth?

Back

Rivers shape the Earth through processes of erosion and sediment deposition.

Front

What units are used to measure speed?

Back

Speed is typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is sediment?

Front

What is a river delta?

Back

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

Front

What factors affect river speed?

Back

River speed can be affected by the gradient of the riverbed, the volume of water, and the amount of sediment.

Front

What is the relationship between river speed and sediment transport?

Back

Faster rivers can carry more sediment, while slower rivers tend to deposit sediment.

Front

What is weathering?

Back

Weathering is the breakdown of rocks and minerals into smaller particles due to environmental factors.
