Weathering, Erosion, & Deposition

Front

What is acid rain?

Back

Acid rain is precipitation that contains high levels of sulfuric and nitric acids, often caused by pollution from factories. It can dissolve rocks and damage buildings.

Front

What is organic activity in weathering?

Back

Organic activity refers to the process of weathering caused by living organisms, such as plants and animals, which can break down rocks through biological processes.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through physical forces like freeze-thaw cycles.

Front

What is deposition?

Back

Deposition is the geological process where sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is thermal expansion and contraction?

Back

Thermal expansion and contraction is the process where rocks expand when heated and contract when cooled, leading to cracking and breaking.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is frost wedging?

Back

Frost wedging is a type of mechanical weathering that occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water, acids, or other chemicals.

Front

What role do plants play in weathering?

Back

Plants contribute to weathering through organic activity, where roots can grow into cracks in rocks, breaking them apart as they expand.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.
