With reference to soil erosion, consider the following statements: Gul...
Soil erosion is a natural process in which the top layer of soil is removed or displaced by wind, water, or other external forces. It is a significant environmental issue that can lead to the loss of fertile soil, reduced agricultural productivity, and increased sedimentation in water bodies. In the context of soil erosion, let's analyze the given statements:
1. Gully erosions are commonly found on dry and arid-levelled lands.
Gully erosion refers to the formation of deep channels or gullies in the landscape due to the concentrated flow of water. It typically occurs in areas with high rainfall intensity and poor vegetation cover. However, the statement incorrectly suggests that gully erosion is commonly found on dry and arid-levelled lands, which is not accurate. Gully erosion is more common in areas with higher rainfall and steep slopes, where the water flow is concentrated and the soil is easily eroded.
2. Sheet erosion is common on steep slopes.
Sheet erosion is the removal of a thin, uniform layer of soil from the land surface by rainfall or flowing water. It occurs when raindrops detach soil particles and transport them over the surface, leading to a gradual loss of topsoil. Steep slopes are more prone to sheet erosion as gravity accelerates the water flow, increasing the erosive force. Therefore, the statement accurately states that sheet erosion is common on steep slopes.
3. Ravines in India are found in Madhya Pradesh, West Bengal, and Tamil Nadu.
Ravines are deep, narrow gorges or valleys formed by the erosion of soil and rocks by water. They are typically found in arid and semi-arid regions with low vegetation cover and high-intensity rainfall events. While the given statement mentions some states where ravines are found, it does not provide a comprehensive list. Ravines can be found in various parts of India, including Rajasthan, Gujarat, Uttar Pradesh, and Bihar, among others. Therefore, the statement is partially incorrect.
In conclusion, statement 2 is correct as sheet erosion is indeed common on steep slopes. However, statement 1 is incorrect as gully erosion is more common in areas with high rainfall and steep slopes. Statement 3 is partially correct as ravines can be found in several states, not just the ones mentioned. Therefore, the correct answer is option D) 3 only.

With reference to soil erosion, consider the following statements: Gul...
- Wind and water are powerful agents of soil erosion because of their ability to remove soil and transport it.
- Wind erosion is significant in arid and semi-arid regions.
- In regions with heavy rainfall and steep slopes, erosion by running water is more significant. Water erosion which is more serious and occurs extensively in different parts of India, takes place mainly in the form of sheet and gully erosion.
- Sheet erosion takes place on level lands after a heavy shower and the soil removal is not easily noticeable. But it is harmful since it removes the finer and more fertile top soil. Hence statement 2 is not correct.
- Gully erosion is common on steep slopes. Gullies deepen with rainfall, cut the agricultural lands into small fragments and make them unfit for cultivation. Hence statement 1 is not correct.
- A region with a large number of deep gullies or ravines is called a badland topography. Ravines are widespread, in the Chambal basin (Madhya Pradesh). Besides this, they are also found in Tamil Nadu and West Bengal. Hence statement 3 is correct
