Geography 8 Class Notes
Chapter: Weathering, Erosion, and Mass Wasting
1. Fill in the Blanks
1. Rainwater that is slightly acidic dissolves limestone through the process of carbonation.
2. Yellowish-brown rust on iron-rich rocks is formed by oxidation.
3. Frost action is most common in areas with fluctuating temperatures.
4. Chemical weathering is fastest in warm and wet climates.
5. Plants break rocks apart through biological weathering.
6. The process of rock layers peeling off like onion layers is called exfoliation.
2. Conceptual Questions
Q1. What is Weathering?
Answer: Weathering is the process where rocks are broken down into smaller pieces by natural
forces like wind, water, temperature changes, and living organisms. It happens on the spot
without moving the rock particles elsewhere.
Q2. What is Physical Weathering? Explain its main types.
