Questions and Answers

What is the primary reason for the unequal heating of Earth's surface?

  • Altitude variations across the globe
  • Variation in the reflective properties of the surface
  • Humidity levels in different climate zones
  • Differences in the angle of the Sun's rays hitting the Earth (correct)

How does insolation vary with latitude?

  • It increases towards the poles
  • It decreases towards the equator
  • It remains constant globally
  • It varies significantly, being higher near the equator and lower near the poles (correct)

What effect does the oblique angle of the Sun's rays near the poles have on energy absorption?

  • Creates a greenhouse effect increasing energy retention
  • Has no impact on energy absorption
  • Decreases absorption due to a larger spread of energy (correct)
  • Increases absorption due to better distribution of energy
