Summary
This document provides an introduction to the types of weathering. It discusses physical weathering processes like exfoliation and frost wedging, and chemical weathering processes such as carbonation, hydrolysis, oxidation, and hydration. Finally, the document covers biological weathering and the role of plants, animals, and microbes in breaking down rocks.

1 2 3 Express Describe how Perform simple appreciation for rocks undergo experiment on the importance of weathering weathering weathering in shaping the Earth’s landscape The breaking down or dissolving of rocks and minerals on the surface of the Earth. Exfoliation is when the outer layers of a rock peel off in thin sheets. Frost wedging happens when water gets into small cracks in rocks. This happens when rocks heat up and expand during the day, then cool down and contract at night. This occurs when plant roots grow into small cracks in rocks. This is where salt crystals form and grow in the cracks and pores of rocks. This is the mixing of water Acid rain with carbon dioxide to make carbonic acid. Carbon dioxide + water = carbonic acid Sulfur dioxide + water = sulfuric acid Nitrous oxide + water = nitrous acid The breakdown of rock by acidic water to produce clay. The breakdown of rocks that contain iron that react with oxygen and water. Hydration occurs when water is absorbed into the crystal structure of the minerals, causing it to expand. This occurs when plants, animals, and microbes contribute to rock breakdown. I hope you learn something new today!
