Chapter 8 Weathering and Erosion

Mixture of weathered rock, minerals, and organic matter

Type of weathering that breaks rock into smaller pieces without changing its mineral 

A large area of north-south trending mountain ranges and valleys located in Nevada and Utah

The process that moves weathered material from one location to another

Breaks a rock into pieces as water freezes, expands, and melts in the cracks of a rock

A layer in a soil profile

Occurs when the water level in a river rises above the usual height and the river overflows

A wide, flat valley located along the sides of some rivers and streams 

A destructive process that breaks down and changes rocks that are exposed at Earth's surface

Erosion caused by gravity

A landform consisting of loose sand and gravel that is located along the shoreline

When sediments are laid down in a new location by water, rain, waves, glaciers, wind or graity

The slow process of sediments moving down-hill, pulled by the force of gravity

Rain containing sulfuric acid formed from water vapor and gases released when coal is burned

Rapid, gravity-caused events that move soil, loose rocks, and boulders 

Streambeds that only contain water during periods of heavy rain or flood

Weathering that occurs when rocks and minerals are exposed on the surface from water and gases

A large, slow-moving mass of ice and snow
