FAQs on Soil Erosion And Conservation - 2 Class 5 Worksheet Science

1. What is soil erosion and why is it a problem?
Ans.Soil erosion is the process by which the top layer of soil is worn away, often due to wind, water, or human activities like farming. It is a problem because it can lead to loss of fertile land, reduced agricultural productivity, and increased sediment in rivers and streams, which can harm aquatic ecosystems.
2. What are some common causes of soil erosion?
Ans.Common causes of soil erosion include heavy rainfall, deforestation, overgrazing by animals, improper agricultural practices, and urban development. These factors can disturb the soil structure and make it more susceptible to being washed or blown away.
3. How can soil erosion be prevented?
Ans.Soil erosion can be prevented through various methods such as planting cover crops, using terracing on slopes, maintaining vegetation, practicing crop rotation, and building barriers like retaining walls. These practices help to hold the soil in place and reduce runoff.
4. What is the role of vegetation in preventing soil erosion?
Ans.Vegetation plays a crucial role in preventing soil erosion by providing ground cover that shields the soil from rain impact, reducing runoff, and stabilizing the soil with their roots. Healthy plant growth also improves soil structure and increases water retention.
5. What are the consequences of soil erosion on the environment?
Ans.The consequences of soil erosion on the environment include loss of soil fertility, decreased agricultural yields, increased pollution in waterways due to sediment runoff, and loss of habitat for wildlife. It can also contribute to climate change by releasing stored carbon from the soil.
