What is oxidation in the context of weathering?

Back

A chemical weathering process where oxygen reacts with minerals, particularly iron, to form rust.

Front

What is gravity erosion?

Back

A type of erosion that occurs when rocks or soil move down a slope due to the force of gravity.

Front

What is wind erosion?

Back

A type of erosion that occurs when wind blows and carries away loose, weathered materials.

A type of erosion caused by glaciers that move and reshape the landscape as they advance.

Front

What is Horizon B in soil?

The soil horizon where clay and weathered rock accumulate, often referred to as the subsoil.

Front

What is Horizon O and A in soil?

The soil horizons where organic matter and microscopic bacteria live, rich in nutrients.

Front

What is the role of water in erosion?

Back

Water can erode soil and rock through processes like rainfall runoff, rivers, and ocean waves.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken materials to new locations.
