Which one of the following is not correct about Sargasso Sea?

  1. A.It is characterized with anticyclonic circulation of ocean currents.
  2. B.It records the highest salinity in Atlantic Ocean.
  3. C.It is located west of Gulf Stream and east of Canary Current.
  4. D.It confined in gyre of calm and motionless water.

Correct answer

C. It is located west of Gulf Stream and east of Canary Current.

Explanation

The correct answer is C. The location is reversed: the Sargasso Sea lies east of the Gulf Stream and west of the Canary Current, not the other way round.

The Sargasso Sea is in the North Atlantic and is the only sea with no land coast. Its boundaries are ocean currents of the North Atlantic Gyre: the Gulf Stream on the west, the North Atlantic Current on the north, the Canary Current on the east and the North Equatorial Current on the south. These currents turn clockwise around it, an anticyclonic circulation, leaving a calm, warm centre where floating Sargassum seaweed collects. High evaporation and little rainfall or river inflow give it the highest surface salinity of the Atlantic, about 37 parts per thousand.

Option A is wrong to pick because the clockwise gyre around it is indeed anticyclonic. Option B is wrong to pick because its salinity is the highest in the Atlantic. Option D is wrong to pick because it is a calm pool of water enclosed by the gyre.

Exam tip: Sargasso Sea = sea without a coast; Gulf Stream west, Canary Current east; highest Atlantic salinity.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude. Select the correct answer using the code given below.

  1. A.1 and 2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
