Questions and Answers

What is the primary role of ocean currents in transferring heat energy?

  • To warm up the poles
  • To transfer heat from temperate to tropical zones
  • To transfer heat from tropical to temperate zones (correct)
  • To cool down the equator region

    • How does unequal insolation impact the distribution of air temperature on Earth?

  • It leads to uniform air temperature worldwide
  • It results in warmer air at the equator and cooler air at the poles (correct)
  • It causes warmer air at the poles and cooler air at the equator
  • It has no impact on air temperature distribution

    • In the context of ocean currents, where do warm currents generally move?

  • Away from the poles towards the equator
  • Away from the equator towards colder poles (correct)
  • Towards the equator from the poles
  • Towards the equator from the equator

    • What is the effect of ocean currents on maintaining a balance of energy over Earth's surface?
