#Day 4 Question 3

What are the major factors that cause soil erosion?

Thank You.​

Answer 1

Explanation:

The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away

Major causes of soil erosion are as follows⤵

1. Deforestation for Agriculture is One of the Top causes of Soil Erosion-

The increasingly high demand of a growing population for commodities such as coffee, soybean, palm oil or wheat is clearing land for agriculture. Unfortunately, clearing autochthonous trees and replacing them with new tree crops that don’t necessarily hold onto the soil increases the risks of soil erosion.

2. Soil Erosion is also caused by Overgrazing, which causes Floods too-

Overgrazing is caused by intensive cattle raising. As plants don’t have the recovery period they need, they end up being crushed and compacted by cattle. In this process, topsoil sediments are transported elsewhere. As for the remaining soil, it can lose its infiltration capacity, which means more water getting lost from the ecosystem and a harder time for new plants to grow.

3. Agrochemicals cause Soil Erosion and Degradation-

The use of chemicals under the form of pesticides and fertilizers on (often) monocultural crops is a very usual way of helping farmers improve their yields. However, the excessive use of phosphoric chemicals ends up causing an imbalance of microorganisms in the soil moisture, stimulating the growth of harmful bacteria. As the soil gets degraded, the risk of erosion increases and the sediments sweep (via the actions of water and wind) into rivers and nearby regions, possibly contaminating nearby ecosystems.

4. Construction and Recreational Activities-

Setting up buildings and roads also have their share of responsibility when it comes to soil erosion as they don’t allow for the normal circulation of water. Instead, it runs off to flood nearby lands, speeded up erosion in these areas. Moreover, motor-based activities such as motocross also have the potential to disturb ecosystems and change (even if at a smaller scale compared with other causes) and erode the soil.
