Review Constructive/Destructive Forces

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up landforms, such as deposition of sediments, volcanic eruptions, and the formation of mountains.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion, weathering, and volcanic eruptions.

Front

How is a delta formed?

Back

A delta is formed by the deposition of sediments carried by a river at its mouth, which is a constructive process, and the erosion of riverbanks upstream, which is a destructive process.

Front

What role does wind play in shaping sand dunes?

Back

Wind shapes sand dunes by moving sand particles from one place to another, creating hills of sand through the processes of erosion and deposition.

Front

What factors influence the formation of sand dunes?

Back

The speed and direction of the wind, and the size and shape of the sand particles influence the formation of sand dunes.

Front

What is erosion?

Back

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

Front

How do sea walls protect coastlines?

Back

Sea walls are structures built along coastlines to absorb and reflect wave energy, reducing the impact of erosion on the land.

Front

What data can be collected to study erosion?

Back

Data such as the type of soil and the speed of water flow can be collected to study how erosion shapes landscapes.

Front

How do scientists predict volcanic eruptions?

Back

Scientists use technology such as satellite images and seismic activity monitoring to predict volcanic eruptions.

Front

What is the impact of vegetation on erosion?

Back

Vegetation helps to reduce erosion by stabilizing the soil with roots and absorbing water, which decreases runoff.
