What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical changes in their composition, often involving reactions with water, acids, or gases.

Front

What type of rock is formed from heat and pressure?

Back

Metamorphic rock is formed from existing rocks that change due to heat and pressure.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is deposition?

Back

Deposition is the process where sediment is laid down or dropped off in a new location after being transported.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks in place, while erosion involves the movement of those broken materials to a new location.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often transported by water, wind, or ice.

Front

What role does water play in weathering?

Back

Water can cause both chemical and mechanical weathering; it can dissolve minerals and also freeze and expand in cracks, breaking rocks apart.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including the processes of igneous, sedimentary, and metamorphic rock formation.
