Statement Analysis:
1. Gully erosions are commonly found on dry and arid-leveled lands.
- This statement is incorrect. Gully erosion is actually more commonly found in areas with high rainfall and poor soil management practices. It occurs when water flow concentrates in narrow channels, causing deep cuts in the soil.
2. Sheet erosion is common on steep slopes.
- This statement is correct. Sheet erosion occurs when thin layers of soil are removed uniformly from the surface of the land. Steep slopes are more prone to sheet erosion due to the increased speed of water flow.
3. A region with a large number of deep gullies or ravines is called a badland.
- This statement is correct. Badlands are regions characterized by severe erosion, typically with deep gullies, ravines, and barren land. These areas are usually unsuitable for agriculture and other human activities due to the extensive erosion.
Conclusion:
The correct statement among the given options is option B, which is "3 only." Gully erosion is not specific to dry and arid-leveled lands, but rather associated with poor soil management practices and high rainfall. Sheet erosion is indeed common on steep slopes, while badlands are regions with significant erosion features like deep gullies and ravines.

With reference to soil erosion, consider the following statements:1. G...
- 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, cutting the agricultural lands into small fragments and making 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. Ravines are widespread in the Chambal basin. Besides this, they are also found in Tamil Nadu and West Bengal. Hence statement 3 is correct.
