Soil erosion is the removal of the top layer of soil by running water, brings on human activities is known as soil erosion. Human activities responsible for soil erosion are: 1.Deforestation: Cutting down of trees in forest and cleaning land for agriculture, Roads, industries and human habitation is one of the chief causes of soil erosion.
Name the following: When heavy rainfall washes away the topmost layer of the soil Is this a) erosion, b) leaching or c) sheet erosion. Asked by ammugrade10 | 18 August, 2022, Aug:%i:Thursday. ANSWERED BY EXPERT. CBSE VII - Science. Explain how soil pollution and soil erosion could be prevented.
Types of Soil Erosion : (a) Gullies : The running water cuts through the clayey soils and makes deep channels/gullies. The unfit land caused by gullies is called bad land or ravines. (b) Sheet erosion : Water flows as a sheet over large areas down a slope. The top soil is washed away. This process is known as sheet erosion.
Answer: researcher. Explanation: Based on the context provided, Michelle's job role is likely that of a Researcher or a Data Scientist working in the field of scientific research, particularly focused on soil erosion.
The following are five important measures taken to prevent soil erosion and ensure soil conservation: Terrace Farming - On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. Terrace farming is practiced with successful results in Japan, South-East Asia and the USA.
Human activities such as deforestation leads to cutting of trees which causes soil erosion as roots binding the soil gets removed. And natural forces such as tsunami, tornado, high wind velocity and local water bodies cause gully erosion and sheet erosion which leads to removal of thin sheet of soil (in gully erosion by creating gullies and ...
Soil erosion is a natural process that occurs as a result of the hydrologic cycle. When rainwater falls, it flows downhill as runoff toward an accumulation of water. As it flows, the water can carry away the topsoil of a field. Topsoil is the top layer of soil that contains a high concentration of nutrients to support plant growth.
Overgrazing often results in soil erosions, the destruction of vegetation and other problems related to these processes. Overgrazing can reduce ground cover, enabling erosion and compaction of the land by wind and rain. Overgrazing is also one of the leading cause of climate change. Also overgrazing cause- tramping, urination, defecation and ...

ASSERTION (A): Ploughing along the contour lines decelerate the flow of water down the slopes. This is called Contour Ploughing. REASON(R): Terrace cultivation restricts erosion. This type of agriculture practice is done in Western and Central Himalayas. * 1 point a. Both (A) and(R) are true and (R) is the correct explanation of (A). b.
