Explanation: The Deccan Plateau is a significant geographical feature in the southern part of India, bounded by the Eastern and Western Ghats. The Eastern Ghats run along the eastern coast of India, while the Western Ghats run along the western coast. These mountain ranges play a crucial role in the climate and topography of the region.
The Deccan Plateau is characterized by a drier climate compared to the Eastern and Western Ghats. This difference in climate is primarily due to the orographic effect of the Western Ghats. The Western Ghats act as a barrier to the moisture-laden winds from the Arabian Sea, causing them to rise and cool, leading to significant precipitation on the windward side. This results in a wetter climate on the western side of the Ghats, which is evident in the dense forests and high biodiversity of the Western Ghats.
In contrast, the Deccan Plateau, being an inland region, does not receive as much rainfall. The plateau's climate is influenced by its distance from the coast and the rain shadow effect created by the Western Ghats. As a result, the Deccan Plateau experiences a drier climate, with less dense vegetation and a different ecosystem compared to the Ghats.
The Eastern Ghats, while not as high as the Western Ghats, also contribute to the climate of the eastern coast of India. However, the impact of the Eastern Ghats on the climate is less pronounced compared to the Western Ghats due to their lower elevation and the fact that they are not as effective in blocking moisture-laden winds from the Bay of Bengal.
In summary, the Deccan Plateau's drier climate is a result of its inland location and the orographic effect of the Western Ghats, which causes significant precipitation on the western side of the Ghats, leaving the Deccan Plateau with a drier climate. This understanding of the geographical features and their impact on climate is crucial for comprehending the diverse ecosystems and climatic zones in India.
