Class 5 Science Chapter 4- Soil Erosion and Conservation @worldofworksh...
1. What is Soil Erosion? Soil erosion is when the top layer of soil, which is full of nutrients and helps plants grow, gets worn away. This can happen because of water, wind, or even human activities like farming and construction. Imagine soil as a blanket that covers the earth. When this blanket is removed or damaged, plants can’t grow well, and the land can become barren. 2. Causes of Soil Erosion Water: Heavy rain can wash away soil, especially on slopes. Rivers and streams can also carry soil away. Wind: In dry areas, strong winds can blow loose soil away. Human Activities: Cutting down trees (deforestation), overgrazing by animals, and poor farming practices can disturb the soil and make it more prone to erosion. 3. Why is Soil Erosion a Problem? Loss of Fertile Land: Erosion removes the topsoil, which is the most fertile part of the land, making it harder for plants to grow. Water Pollution: Soil that is washed away can end up in rivers and lakes, causing pollution and harmi...
