Front

What is the process in which rock is broken down into smaller pieces?

Back

Weathering

Front

What is deposition in the context of water?

Back

Deposition occurs when water slows down and drops off sediments, forming features like deltas.

Front

How can a model demonstrate the formation of a delta?

Back

A model can show delta formation by pouring water into a stream table filled with dirt, allowing sediments to be deposited at the end in a triangular shape.

Front

What are the main agents of weathering?

Back

The main agents of weathering include water, ice, wind, and biological activity.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

How does weathering differ from erosion?

Back

Weathering is the breakdown of rocks in place, while erosion involves the movement of those broken materials.

Front

What is a delta?

Back

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

Front

What role does gravity play in the formation of landforms?

Back

Gravity influences the movement of materials, contributing to processes like erosion and landslides.

Front

What is the significance of sediment in landform development?

Back

Sediment is crucial for forming various landforms, as it is deposited by water, wind, or ice.

Front

What is the impact of human activity on landforms?

Back

Human activities, such as construction and mining, can significantly alter landforms through erosion and deposition.
