Objects and wind moving over distance and time on Earthʹs surface are
A)always deflected to the right by the friction force.
B)always deflected from a straight path to the west in the Southern Hemisphere.
C)apparently deflected from a straight path to the right in the Northern Hemisphere.
D)affected only by the pressure gradient and friction force.

Question

Quizplus · Accepted Answer

This is known as the Coriolis Effect, which causes objects and wind to appear deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is caused by the rotation of the Earth. The pressure gradient and friction force also play a role in the movement of objects and wind on Earth's surface. Option A and B are incorrect as there is no universal deflection to the right or west respectively. Option D is incorrect as it does not account for the Coriolis Effect.
