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

Front

What is the force behind mass movements?

Back

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

Front

What is a slump in the context of mass movements?

Back

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

Front

Which soil particle is the largest?

Back

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

Front

Why does water expanding when it freezes contribute to weathering?

Back

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

Front

Are there minerals in soil?

Back

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

Front

What is weathering?

Back

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

Front

What is the difference between physical and chemical weathering?

Back

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

Front

What role does water play in soil formation?

Back

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

Front

What is mass movement?

Back

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

Front

What is creep in the context of mass movements?

Back

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