What is weathering?
Weathering is the process by which rocks are broken down into smaller pieces by physical, chemical, or biological means.
What is erosion?
Erosion is the process that transports rock materials from one location to another, typically by wind, water, or ice.
How does weathering differ from erosion?
Weathering involves the breakdown of rocks in place, while erosion involves the movement of rock particles to new locations.
What is physical weathering?
Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.
What is chemical weathering?
Chemical weathering involves the breakdown of rocks through chemical reactions, often involving water and gases.
What is biological weathering?
Biological weathering is the breakdown of rocks by living organisms, such as plants, animals, and microbes.

How does water contribute to erosion? | Water contributes to erosion by carrying rock particles downstream in rivers and streams. |
What role does wind play in erosion? | Wind can transport small rock particles over long distances, contributing to erosion. |
How does ice cause erosion? | Ice causes erosion through processes like glaciation, where moving glaciers grind and carry away rock material. |
What is the main outcome of erosion? | The main outcome of erosion is the redistribution of rock materials, which can lead to the formation of new landforms. |
