What is deposition in the context of a stream?

Back

Deposition is the process by which sediment carried by a stream is dropped or settled in a new location, often forming features like deltas.

Front

What is erosion?

Back

Erosion is the process of wearing away rocks and soil by natural forces such as water, wind, or ice.

What evidence suggests that a glacier has moved through a valley?

Back

The shape of the valley can indicate glacial movement, as glaciers carve out U-shaped valleys.

Front

How do wind and sand contribute to landform changes?

Back

Wind and wind-blown sand can weather rocks, creating grooves and pits over time.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it deposits sediment as it slows down.

Front

What happens to a river's speed as it approaches its mouth?

Back

The river slows down as it approaches its mouth, which allows it to deposit sediment.

Front

What is weathering?

Back

Weathering is the breakdown of rocks into smaller pieces due to environmental factors like temperature changes, water, and biological activity.

Front

What role do glaciers play in shaping landscapes?

Back

Glaciers can flatten land and deposit rocks as they melt, significantly altering the landscape.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces from one location to another.

Front

How can plants and animals contribute to weathering?

Back

Plants and animals can contribute to weathering through biological activity, such as roots breaking rocks apart.
