Which one of the following is not a cold current ?
- A.Western Australian Current
- B.Eastern Australian Current
- C.Benguela Current
- D.Peru Current
Correct answer
Explanation
The correct answer is B, Eastern Australian Current. It is a warm current that flows south along the east coast of Australia, carrying tropical water from the Coral Sea.
Ocean currents follow a simple pattern in each ocean basin: currents on the western side of an ocean, that is along the east coasts of continents, flow away from the equator and are warm, while currents on the eastern side of an ocean, along the west coasts of continents, flow towards the equator and are cold. The East Australian Current is part of the South Pacific gyre and is the western boundary current of that ocean. Cold currents along west coasts also help to create deserts there, such as the Atacama, the Namib and the Great Victoria Desert.
A is wrong: the West Australian Current flows north along Australia's west coast and is cold.
C is wrong: the Benguela Current off south-west Africa is cold and helps form the Namib Desert.
D is wrong: the Peru or Humboldt Current off South America is cold and rich in fish.
Exam tip: east coasts of continents get warm currents, west coasts get cold currents.

Radiation fog is associated with radiation cooling of the land at night. 3. Advection fog forms when moisture is blown over a cold surface and is chilled by contact. Which of the statements given above are correct ?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show answer
All three statements are correct descriptions of fog and its two main types. Fog forms when air near the ground cools to its dew point and its water vapour condenses on tiny dust and smoke particles, so it is in effect a cloud at or near ground level.
