4- Weathering, Erosion, and Deposition

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

What is erosion?

Back

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 deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass.

Front

What causes glaciers to move?

Back

Pressure from the weight of the ice and the underlying layers.

Front

What is humus?

Back

Decayed organic matter that comes from dead plants and animals, enriching the soil.

Front

What is frost wedging?

Back

A type of mechanical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is the role of groundwater in erosion?

Back

Groundwater can dissolve minerals and carry away sediments, contributing to the erosion of rocks and soil.

Front

What is a landslide?

Back

A sudden and fast movement of a large amount of earth material down a slope, which is NOT considered a slow change to Earth's surface.

Front

What are the main agents of erosion?

Back

Water, wind, ice, and gravity.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.
