Deccan plateau comes under area ofa)inadequate rainfall.b)high rainfall.c)medium rainfall.d)low rainfall.Correct answer is option 'D'. Can you explain this answer?

Question

Answer

There is heavy rainfall on the western coast of India but very little in the Deccan because the Deccan plateau is situated in the rain shadow of the Western Ghats. The Deccan Plateau to the east of the Western Ghats receives significantly less rainfall than the coasts. As the summer (wet) monsoons approach the West Coast of India, they rise up the western Ghats (mountains) and the air cools. This cool air is less able to hold moisture and it is released as rainfall.

Answer

(Correct Option:- D, Low Rainfall)

There is heavy rainfall on the western coast of India but very little in the Deccan because the Deccan plateau is situated in the rain shadow of the Western Ghats. The Deccan Plateau to the east of the Western Ghats receives significantly less rainfall than the coasts. As the summer (wet) monsoons approach the West Coast of India, they rise up the western Ghats (mountains) and the air cools. This cool air is less able to hold moisture and it is released as rainfall.

Answer

The Deccan Plateau receives low rainfall because it is located in a rain shadow region, which is an area of land where mountain ranges block rainy weather:
Rain shadow
The Western Ghats block moisture-laden winds from the Arabian Sea, causing the leeward side of the plateau to receive less rainfall.
Interior location
The plateau's interior location results in dry air masses, which limits rainfall.
Other factors
Other factors that contribute to the low rainfall include the plateau's distance from the coast, rugged topography, disrupted wind patterns, and seasonal variations in rainfall.
Elevation
The plateau's elevation of about 2,000 feet above sea level makes it drier than the rest of India.

Answer

Deccan plateau comes under the area of low rainfall.

The Deccan plateau is a vast elevated region in southern India, covering an area of about 1.9 million square kilometers. It is characterized by its flat-topped plateaus, basaltic lava flows, and rugged topography. The region experiences a predominantly dry climate, with low rainfall throughout the year.

Reasons for low rainfall in the Deccan plateau:
1. Rain Shadow Effect: The Deccan plateau is located in the rain shadow region of the Western Ghats. The Western Ghats act as a barrier to the southwest monsoon winds, causing them to rise and release moisture on the windward side, which receives heavy rainfall. As a result, the leeward side, which includes the Deccan plateau, experiences significantly lower rainfall.

2. Distance from the coast: The Deccan plateau is located at a considerable distance from the coast. Coastal regions generally receive higher rainfall due to the influence of maritime air masses. However, as the Deccan plateau is located far inland, it does not benefit from the moisture-bearing winds from the Arabian Sea.

3. Topography and wind patterns: The Deccan plateau is characterized by its elevated topography, with numerous hills and plateaus. This rugged terrain disrupts the normal wind patterns, leading to less moisture-laden winds reaching the plateau. The absence of significant water bodies also contributes to the low humidity levels and reduced rainfall in the region.

4. Intermontane valleys: The Deccan plateau is interspersed with intermontane valleys, which are low-lying areas between mountain ranges. These valleys act as rain shadows, preventing moisture-bearing winds from reaching the plateau and resulting in reduced rainfall.

5. Seasonal variations: The Deccan plateau experiences distinct seasons, with a hot and dry summer followed by a relatively cooler and drier winter. The monsoon rains are limited and erratic, with most of the rainfall occurring during the months of June to September. This limited duration and variability of rainfall further contribute to the overall low rainfall in the region.

In conclusion, the Deccan plateau comes under the area of low rainfall due to its location in the rain shadow region, distance from the coast, rugged topography, disrupted wind patterns, presence of intermontane valleys, and seasonal variations in rainfall.
