Explanation
The Indian Desert (Thar Desert) receives very low rainfall, generally less than 150 mm annually. Therefore, Statement 2 is correct.
Statement 1 is incorrect because streams formed during rainfall in desert regions are mostly ephemeral (temporary) and do not reach the sea. They usually disappear in sandy terrain or get absorbed.
Key Points
• The Thar Desert receives very low rainfall (<150 mm).
• Streams in this region are seasonal and temporary.
• Most water channels do not reach the sea.
• High evaporation and infiltration reduce surface flow.
Additional Facts
• The Luni River is a major river in the desert but does not reach the sea.
• Water resources in desert regions are extremely limited.
• Vegetation is adapted to arid conditions.
