The Indian desert lies towards the western margins of the Aravali Hills. The main features of the Indian desert are:
- It is an undulating sandy plain covered with sand dunes.
- This region receives very low rainfall below 150 mm per year.
- It has arid climate with low vegetation cover.
- Streams appear during the rainy season. Soon after they disappear into the sand as they do not have enough water to reach the sea.
- Barchans (crescent-shaped dunes) cover larger areas but longitudinal dunes become more prominent near the Indo-Pakistan boundary.
