Question: What is the difference between weathering and erosion?

Answer: Weathering is the physical or chemical breakdown of rock. Erosion is the removal of weathered pieces of rock to another place

Question: What is the difference between mechanical and chemical weathering?

Answer: Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.

Question: How do water, air, and organisms cause chemical weathering?

Answer: Water, air, and chemicals released by organisms cause chemical weathering of rocks when they dissolve the minerals in a rock. They can also cause chemical weathering by reacting chemically with the minerals in the rock to form new substances.

Question: How do mechanical and chemical weathering work together to speed up the weathering process?

Answer: Mechanical weathering breaks rocks down into smaller pieces. This gives the rock a larger surface area for chemical reactions to take place. Chemical weathering weakens rock, making it easier for it to be broken down by mechanical weathering.

Question: erosion

Answer: the process in which wind, water, ice, or other things move pieces of rock and soil over Earth’s surface (related word: erode)
