Which of the following statements is/are correct?
1. The Indian Desert extends east of the Aravali range.
2. The region has low annual precipitation.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer – Only 2.
Explanation:
- Statement 1 (Incorrect): The Indian Desert (Thar Desert) is situated to the west of the Aravalli Range, not to the east. The Aravalli Range acts as a water divide and obstructs the monsoon winds; consequently, rainfall is extremely scarce in its western region, leading to the formation of the desert.
- Statement 2 (Correct): Annual rainfall in this region is very low (typically less than 150 mm). Due to low precipitation and high evaporation, the climate here is arid, and vegetation is sparse.
Additional Facts:
- Luni River: This is the most prominent—and the only major—river in this desert region, which eventually disappears into the Rann of Kutch.
- Barchans: Crescent-shaped sand dunes, known as 'Barchans,' are found here. These can be observed in abundance near Jaisalmer.
- Minerals: This region is rich in minerals such as gypsum, marble, and copper.
