Question

Consider the following statement:

The source of Waterfall A is Place B.

With the help of the above statement alone, choose the favourable climatic conditions with respect to rainfall in the Place B such that the Waterfall A is perennial.

• A. B needs to receive less rainfall.
• B. B needs to receive frequent rainfall.
• C. B needs to receive a lot of rainfall.
• D. B needs to receive scattered rainfall.

Answer 1

Answer: (B), (C)

The correct options are
B B needs to receive frequent rainfall.
C B needs to receive a lot of rainfall.

Perennial waterfalls are the ones which flow throughout the year. For perennial waterfalls to stay perennial, the sources of water need to be continuous. Considering rainfall to be the source of water in this case, the waterfall must receive a large amount of rainfall regularly.
