Consider the following statements : 1. The Red Sea receives very little precipitation in any form. 2. No water enters the Red Sea from rivers. Which of the statements given above is/are correct ?
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Correct answer
Explanation
The correct answer is C, both 1 and 2. The Red Sea lies in a hot desert belt, gets very little rain and has no permanent river flowing into it.
The Red Sea is a narrow inlet of the Indian Ocean between north-east Africa and the Arabian Peninsula, joined to the Gulf of Aden through the Bab-el-Mandeb strait and to the Mediterranean through the Suez Canal. It is bordered by the Sahara and Arabian deserts, so rainfall averages only a few centimetres a year, while evaporation is very high. No perennial river drains into it; only short seasonal streams, called wadis, flow after rare storms. Heavy evaporation with almost no fresh water coming in makes it one of the saltiest seas connected to the open ocean, with salinity of about 40 parts per thousand.
A is wrong because statement 2 is also true. B is wrong because statement 1 is also true. D is wrong because both statements are correct.
Exam tip: Red Sea: no permanent rivers, little rain, high evaporation, salinity about 40 parts per thousand.

- A.Clouds which do not extend beyond the freezing level
- B.Clouds which extend beyond the freezing level
- C.All types of clouds
- D.Cirrocumulus cloud
Show answer
Collision-coalescence is the way rain forms in warm clouds, whose tops stay below the level where water freezes. In such clouds all droplets are liquid.
