Answer: 

Introduction:

Deltas are landforms that occur at the mouth of rivers where they meet a body of standing water, sea or lake. They are typically formed when the river deposits sediment as it flows into the standing water, creating a fan-shaped pattern of land.

Body:

Western Ghats no deltas due to several reasons:

• Steep Gradient: The rivers of the western Ghats have a steep gradient, which means that they flow rapidly and do not deposit sediment as readily as rivers with a gentler gradient.
• Short Distance: The distance between the western Ghats and the Arabian Sea is relatively short, so the rivers do not have enough time to deposit sediment and form a delta.
• Rocky Terrain: The terrain around the rivers in the western Ghats is often rocky and hilly, which makes it difficult for sediment to accumulate and form a delta.
• Wave Action: The Western Ghats are exposed to high wave action, which means that the sediment deposited at the mouth of the rivers is quickly eroded by the waves. This leads to the formation of beaches instead of deltas.

Conclusion:

The absence of deltas in Western Ghats rivers could be due to the steep gradient of the rivers, their relatively short length, and the fact that they often flow into estuaries rather than directly into the sea. Other factors such as high rainfall, fast-flowing water, and steep topography may also contribute to the lack of delta formation in this region.
