What are 4 things that cause erosion?
Liquid water is the major agent of erosion on Earth.
Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion..

What are the main causes of soil pollution?
Illegal dumping of the solid wastes, polluted water absorbed by the soil, use of chemical fertilizers and pesticides, dumping of minerals, oils, and radioactive wastes are the major causes of soil pollution (Cachada et al. 2018). Soil fertility is severely affected due to the above-mentioned factors.

What is Soil Erosion very short answer?
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

What causes wind class 9?
Ans: The uneven heating of the earth’s surface is the main cause for the winds. On being heated more the air raises up and hence low pressure is created. Hence, the air in high pressure occupy the low-pressure region causing the wind.
What is soil erosion Class 7?
The removal of fertile top soil land by wind or water is called soil erosion. Soil erosion occurs easily in those areas of land which are not covered by vegetation (trees and other plants) or have very little vegetation. The cover of vegetation softens (or reduces) the effect of heavy rains on the soil. …
What are the control measures of soil pollution?
Recycling and Reuse of wastes: To minimize soil pollution, the wastes such as paper, plastics, metals, glasses, organics, petroleum products and industrial effluents etc should be recycled and reused. Ex: Industrial wastes should be properly treated at source. Integrated waste treatment methods should be adopted.
