Worked practice questions

Planetary winds are deflected to the right in which hemisphere?

  1. Northern
  2. Southern
  3. Both alike
  4. Neither one
Show answer and solution

Correct answer: A. Northern

1. The rotation of the Earth bends the path of the winds. 2. The bend is towards the left in the Southern Hemisphere. 3. In the Northern Hemisphere winds are deflected to the right. 4. So the answer is the Northern Hemisphere. _Source: syllabus Science, Ch 13 'Earth as a System: Energy, Matter, and Life'_

Large circular patterns of ocean currents are called:

  1. Bores
  2. Gyres
  3. Waves
  4. Tides
Show answer and solution

Correct answer: B. Gyres

1. The rotation of the Earth deflects moving water masses. 2. They end up travelling in huge closed loops. 3. These loops are called gyres. 4. So the answer is gyres. _Source: syllabus Science, Ch 13 'Earth as a System: Energy, Matter, and Life'_

The North Atlantic Drift is a current that carries:

  1. Dry air inland
  2. Ice to the poles
  3. Warm water north
  4. Cold water south
Show answer and solution

Correct answer: C. Warm water north

1. Ocean currents move heat around the planet. 2. This one reaches high latitudes from the equator. 3. The North Atlantic Drift brings warm water to high latitudes. 4. So the answer is warm water north. _Source: syllabus Science, Ch 13 'Earth as a System: Energy, Matter, and Life'_
