Earth Science-Ch. 5 Weathering Soil and Mass movement

Front

What is weathering?

Back

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

Front

What is mass movement?

Back

The downward movement of soil and rock due to gravity.

Front

Define chemical weathering.

Back

The process that breaks down rocks through chemical reactions, often involving water and substances in the environment.

Front

What is mechanical weathering?

Back

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

Front

What are slumps?

Back

A type of mass movement where a section of soil or rock moves down a slope in a rotational manner.

Front

What are mudflows?

Back

Rapid flows of water-saturated soil and debris that move down slopes.

Front

What is creep?

Back

A slow, gradual movement of soil and rock down a slope, often imperceptible over short periods.

Front

What is a landslide?

Back

A sudden and fast movement of a large amount of earth material down a slope.

Front

What is the composition of silt loam soil?

Back

20% Sand, 70% Silt, 10% Clay.

Front

What role does gravity play in mass movement?

Back

Gravity is the primary force that drives all types of mass movement.
