A) always deflected from a straight path to the west in the Southern Hemisphere.
B) affected only by the pressure gradient and friction force.
C) always deflected to the right by the friction force.
D) apparently deflected from a straight path to the right in the Northern Hemisphere.

Question

Quizplus · Accepted Answer

This is known as the Coriolis effect, which causes objects and winds to appear deflected from a straight path to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The deflection occurs due to the Earth's rotation, which causes a moving object (or wind) to be deflected at a right angle to its direction of motion. The deflection is proportional to the speed of the object and the latitude of its location.
