Constructive and Destructive Forces

Front

What is deposition?

Back

Deposition is the process by which sediment, soil, and rocks are added to a landform or land mass. It occurs when the energy of the transporting medium (like water or wind) decreases, causing materials to settle.

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 flow, and then transported to another location.

Front

What is a volcano?

Back

A volcano is an opening in the Earth's crust where molten rock, ash, and gases from below the Earth's surface can escape to the surface, often creating new landforms.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere, resulting in seismic waves.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

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 like an ocean or lake, and sediment is deposited.

Front

What is a landslide?

Back

A landslide is the movement of rock, earth, or debris down a slope due to gravity, often triggered by factors like rain or earthquakes.

Front

What is constructive force?

Back

Constructive forces are natural processes that build up landforms, such as volcanic eruptions, sediment deposition, and mountain formation.

Front

What is destructive force?

Back

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

Front

What is a sand dune?

Back

A sand dune is a hill of sand formed by the wind, often found in deserts or near beaches, and is a result of deposition.
