Question

a. natural springs in the desert.
b. melting ice in the mountains.
c. rain-fed streams in the plateau.
d. large lakes in the northern plain.

1. how has the location of the himalaya mountains benefited india?

a. roads for trade routes
b. consistent water supply
c. protection from enemies
d. prevention of earthquakes

Explanation:

• For question 9: The Indus, Ganges, and Brahmaputra rivers originate in mountainous regions. Melting ice in the mountains (such as the Himalayas) is a major source of water for these rivers. Natural springs in the desert (A) are not relevant as these rivers are not in desert - like water - scarce regions. Rain - fed streams in the plateau (C) are not the primary source compared to glacial melt. Large lakes in the northern plain (D) are not the main source of these major river systems.
• For question 10: The Himalaya Mountains act as a natural barrier. They provide protection from enemies (C) as they are difficult to cross. While they do contribute to the water supply (B) through glacial melt, the most significant and well - known benefit in a historical and strategic sense is protection. They are not known for providing roads for trade routes (A) in a straightforward way, and they do not prevent earthquakes (D).

Answer:

1. B. melting ice in the mountains.
2. C. protection from enemies.
