Which of the following are warm ocean currents?

  1. A.Kuroshio and California Current
  2. B.North Atlantic Drift and Brazil Current
  3. C.Canaries and Benguela Current
  4. D.West Wind Drift and Falkland Current

Correct answer

B. North Atlantic Drift and Brazil Current

Explanation

The correct answer is B, North Atlantic Drift and Brazil Current. Both the North Atlantic Drift and the Brazil Current carry warm water from low latitudes towards higher latitudes.

As a rule, currents that flow from the equator towards the poles are warm, and those that flow from the poles towards the equator are cold. The Brazil Current flows south along the east coast of South America. The North Atlantic Drift is the extension of the Gulf Stream; it carries warm water to north-west Europe and keeps ports such as those of Norway free of ice in winter. Cold currents usually run along the western coasts of continents in the tropics, where they help form deserts.

A is wrong because the Kuroshio is warm but the California Current is cold. C is wrong because the Canaries Current off north-west Africa and the Benguela Current off south-west Africa are both cold. D is wrong because the West Wind Drift around Antarctica and the Falkland Current off Argentina are both cold.

Exam tip: warm on the east coasts (Gulf Stream, Kuroshio, Brazil), cold on the west coasts in the tropics (California, Canaries, Benguela, Peru).

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.
