Questions and Answers

Why does a ball thrown from the equator towards the North Pole appear to drift east?

  • Because of the Coriolis Effect pushing the ball eastward
  • The gravitational pull of the poles affecting the ball's path
  • Due to the Earth's rotation causing the ball to move faster relative to the ground (correct)
  • Frictional forces acting on the ball

What is responsible for creating strong winds in the tropics known as the Trade Winds?

  • Polar Cell
  • Coriolis Cell
  • Ferrel Cell
  • Hadley Cell (correct)

At what latitudes do the winds at the surface may blow either east or west in the Ferrel Cell?

  • 0-30 degrees
  • 30-60 degrees (correct)
  • 60-90 degrees
  • 90-180 degrees
