Basics Of Soil Science

Step 1: Estimate the typical annual rainfall for each region.
- C. Kutch in Gujarat: This is an arid, desert region. It receives very low rainfall, typically less than 400 mm annually.
- A. Karnataka Plateau: This is a rain-shadow region, east of the Western Ghats. It receives moderate rainfall, typically ranging from 500 mm to 1000 mm.
- D. Eastern Coastal Plain: This region receives rainfall from both the Southwest and Northeast monsoons. The annual rainfall is significant, generally in the range of 1000 mm to 1500 mm.
- B. West Coast: This region lies on the windward side of the Western Ghats and receives extremely heavy orographic rainfall from the Southwest monsoon. It is one of the wettest parts of India, with annual rainfall often exceeding 2500 mm to 3000 mm.
Step 2: Arrange the regions in increasing order of rainfall. Based on the estimates, the correct order is:
Kutch in Gujarat Karnataka Plateau Eastern Coastal Plain West Coast. This corresponds to the sequence C, A, D, B.
