What is a rockslide?

Back

A rockslide is a type of mass movement that involves the sudden and rapid movement of a large amount of rock and soil down a slope.

What is a slump?

Back

A slump is a type of mass movement where a section of soil or rock moves down a slope along a curved surface.

Front

What is soil structure?

Back

Soil structure refers to the arrangement of soil particles and the spaces between them, which affects water movement and root growth.

Front

What is columnar soil structure?

Back

Columnar soil structure is typically found in arid regions and is characterized by vertical columns of soil.

Front

What is chemical weathering?

Back

Chemical weathering is the process by which rocks are broken down by chemical reactions, altering their composition.

Front

What is frost wedging?

Back

Frost wedging is a physical weathering process where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller particles, leading to soil formation.
