constructive and destructive forces

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up landforms, such as mountains and valleys, through processes like volcanic activity and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion and weathering, leading to the wearing away of rocks and soil.

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 is the role of gravity in erosion?

Back

Gravity pulls materials down slopes, contributing to erosion through processes like landslides and rockfalls.

Front

How do rivers cause erosion?

Back

Rivers erode land by wearing away the banks and bed through the force of flowing water, especially on the outside bends of meanders.

Front

What is sediment?

Back

Sediment is small particles of rock, soil, and organic material that are transported by wind, water, or ice.

Front

What factors influence the rate of erosion?

Back

Factors include the speed of water or wind, the type of surface material, vegetation cover, and human activities.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks in place, while erosion involves the movement of those broken materials to new locations.

Front

What is the impact of glaciers on landforms?

Back

Glaciers shape the landscape by eroding land and depositing sediment, creating features like U-shaped valleys and moraines.

Front

What is mass movement?

Back

Mass movement refers to the downward movement of soil and rock due to gravity, including landslides and mudflows.
