Changing the Shape of Land
Fun Facts
- Erosion usually happens very slowly. We can slow down or prevent erosion by using science.
- An example of erosion is when a river carries soil downstream and makes rocks in the river smoother over time.
- Erosion causes changes in the shape of the land over time and can cause major damage!
Why Do We Need To Know About Erosion
Learning about erosion helps us see how it affects farming and why it’s important for farmers to deal with it. When water changes the shape of the land, it can harm the soil used for growing crops. We can use plants to help because their roots hold the soil together and drink up some of the water. Plant science and caring for our environment work together to stop erosion.
Knowing about erosion helps in building things and planning land use. It shows why using certain materials, like rocks, can protect against erosion by wind. This information is useful for building strong buildings and for keeping beaches safe. It shows how understanding erosion can help us look after our environment better and make good rules for using land.
