6 - Chapter 5 Review - Weathering, Soil and Mass Movements

Gravity is the force that causes mass movements, pulling materials down slopes.

A slump is a type of mass movement where a large chunk of land falls down a curved slope all at once.

Sand is the largest particle in soil, larger than silt and clay.

When water freezes, it expands, which can crack and break rocks, leading to weathering.

Yes, soil contains various minerals that are essential for plant growth.

Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means.

Physical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering alters the minerals within the rocks.

Water helps to break down rocks and organic matter, contributing to the formation of soil.

Mass movement refers to the downward movement of soil and rock due to gravity.

Creep is a slow, gradual movement of soil and rock down a slope.
