FAQs on Weathering and Erosion Video Lecture - Science (Curiosity) Class 7 - New NCERT
| 1. What is the difference between weathering and erosion? |  |
Ans. Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological processes, while erosion involves the movement of these broken-down materials from one location to another, often by wind, water, or ice.
| 2. What are the types of weathering? | |
Ans. There are three main types of weathering: mechanical (or physical) weathering, which breaks rocks into smaller pieces without changing their composition; chemical weathering, which alters the minerals within the rocks through chemical reactions; and biological weathering, which is caused by living organisms, such as plants and animals, that contribute to the breakdown of rocks.
| 3. How does erosion impact the environment? | |
Ans. Erosion can significantly impact the environment by removing fertile soil, which can lead to decreased agricultural productivity. It can also cause sedimentation in rivers and lakes, affecting water quality and aquatic habitats. Additionally, erosion can lead to the formation of landforms such as valleys and canyons.
| 4. What natural forces contribute to erosion? | |
Ans. The main natural forces that contribute to erosion include water (from rivers, rain, and waves), wind, ice (from glaciers), and gravity. Each of these forces can transport soil and rock materials, reshaping the landscape over time.
| 5. How can we prevent erosion? | |
Ans. Erosion can be prevented through various methods, such as planting vegetation to stabilize soil, using barriers like silt fences, creating terraces on slopes, and practicing sustainable land use. These methods help reduce the impact of wind and water on the soil and maintain the integrity of the land.
