Questions and Answers

Why do the tropics experience relatively consistent solar radiation throughout the year?

  • The Earth's elliptical orbit brings the tropics closer to the sun.
  • The tilt of the Earth's axis is constant in the tropics.
  • The consistent cloud cover in the tropics reflects solar radiation evenly.
  • The tropics are located in the center of the globe and do not tilt towards or away from the sun. (correct)

What is the average temperature typically observed in tropical rainforests?

  • 35°C
  • 25°C (correct)
  • 45°C
  • 15°C

Which of the following factors contributes most to the high temperatures in tropical rainforests?

  • Strong ocean currents.
  • High levels of industrial activity.
  • Proximity to volcanic activity.
  • Direct and consistent solar radiation. (correct)
