The Indian desert
Indian desert cover a large part of the country. Let us explore it more.
The great Indian desert
The desert lies towards the western margins of the Aravalli hills.
It lies mostly in Rajasthan, with some parts also present in Haryana, Punjab and Gujarat.
A sandy plain, the Thar desert is covered with sand dunes.
The Thar desert actually covers around 200000 square kilometer of area!
The Indus river borders the desert to the west.
Even with the Indus, water supply in this region is scarce, with the desert receiving around 150 mm of rainfall annually.
Streams do appear during monsoon, but they don’t have enough water to drain into the sea. Hence, they disappear.
Inside the region, the river Luni is the only large river.
The climate is arid, and vegetation cover is low due to less water.
The persistent high pressure at that latitude is why the climate is subtropical desert type.
In the north and northeast, the Punjab plains border the desert.
In the south, the Rann of Kutch borders the desert. Enough about what lies around it, let’s now see what’s inside!
The region’s sand ridges are called thul, from which the name Thar is derived.
Sometimes, sand dunes can also be crescent-shaped, these are called barchans.
The best place to see barchans is to visit Jaisalmer. It is one of the famous tourist attractions!
We can find fossils here also. Some of which were almost 180 million years old.
High and low sand dunes are separated by bhakars, which are low barren hills.
Some older dunes can even rise to over 500 feet high!
Due to wind erosion and sand deposition, the soil in the desert is generally infertile.
Only drought resistant trees or scrubs like acacia and the khejri tree are found here.
Species like blackbucks, gazelles, and partridges are found in the region.
We cannot forget about the camel, the ship of the desert.
The Indian desert is also known as the Thar desert.
It is a region with arid climate and low rainfall.
Average annual rainfall is about 150 mm here. Vegetation mostly includes scrubs and trees.
The desert lies mainly in Rajasthan, with some parts in Punjab, Gujarat, and Haryana.
