Weathering: physical, chemical, and biological

In Class 11 Geography, this topic from the chapter “Geomorphic Processes” explains weathering as the breakdown and alteration of rocks at or near Earth’s surface without transporting the material. Students learn how physical weathering acts through temperature changes, pressure release, and frost; how chemical weathering involves processes such as solution, carbonation, oxidation, hydration, and hydrolysis; and how plants, animals, and microorganisms drive biological weathering. The topic also connects climate, rock type, relief, and time with soil formation and landscape development.
