Weathering

The process of breaking down rocks, soil, and minerals through natural elements like wind, water, and biological activity. 

Erosion

The movement and transportation of weathered materials by wind, water, or ice. 

Mechanical weathering

Physical breakdown of rocks without altering their chemical composition. 

Chemical weathering

Decomposition or alteration of rocks through chemical reactions, often involving water or acids. 

Biological weathering

Breakdown of rocks caused by living organisms such as plants, animals, or microbes. 

Minerals

Naturally occurring inorganic substances that form rocks.

Sediment

Wind Erosion

The removal and transport of soil or sand by wind.

Water Erosion

The wearing away and movement of soil or rock by flowing water. 

Ice Erosion
