Constructive and Destructive Forces

Front

What are constructive forces?

Back

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

Front

What are destructive forces?

Back

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

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What factors influence the rate of erosion?

Back

Factors include the type of soil, vegetation cover, climate, and the speed of water or wind.

Front

What is a watershed?

Back

A watershed is an area of land where all the water that falls as precipitation drains into a common outlet, such as a river or lake.

Front

What happens to sediment as the velocity of a stream increases?

Back

As the velocity of a stream increases, it can carry larger and heavier particles.

Front

What are aretes?

Back

Aretes are sharp ridges that form between two glacial valleys.

Front

What are sea caves?

Back

Sea caves are large holes in the rock at the bottom of sea cliffs, formed by the erosive action of waves.

Front

What is the relationship between discharge and particle size in a stream?

Back

Higher discharge (volume of water) allows a stream to carry bigger and more particles.

Front

What are U-shaped valleys?

Back

U-shaped valleys are formed by glacial erosion, characterized by a wide, flat bottom and steep sides.
