Weathering and Erosion Quiz

Chemical or physical process that breaks down rocks into smaller pieces

• Erosion

• Chemical Weathering

• Subduction

• Weathering

Mechanical weathering process that occurs when water freezes in the cracks of rocks and expands, causing the rock to break apart

• Ice Wedging

• Rust

• Acid Precipitation

• Humus

The grinding away of rock by other rock particles carried in water, ice, or wind

• Differential Weathering

• Weathering

• Abrasion

• Top Soil

Rain, sleet, or snow that contains a high concentration of acids

• Condensation

• Subsoil

• Leaching

• Acid Precipitation

A chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust

• Acid Rain

• Abrasion

• Oxidation

• Metamorphism

The process by which softer, less weather resistant rocks wear away and leave harder, more weather resistant rock behind

• Mechanical Weathering

• Weathering

• Abrasion

• Differential Weathering

Process by which weathered rock and soil are moved from one place to another.

• Erosion

• Weathering

• Differential Erosion

• Differential Weathering

Removal of dissolved materials from soil by water moving downwards

• Leaching

• Permeability

• Abrasion

• Weathering

A fan-shaped mass of material deposited at the mouth of a stream

• Omega

• Delta

• Artemis

• Beta

The breakdown of rock into smaller pieces by physical means

• Weathering

• Mechanical Weathering

• Chemical Weathering

• Rust
