Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The deflection of prevailing winds and ocean currents in the Northern Hemisphere is called
A
eccentricity
B
refraction
C
the Coriolis effect
D
the Doppler effect
Explanation: 

Detailed explanation-1: -Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.

Detailed explanation-2: -What is the Coriolis effect? The Earth’s rotation means that we experience an apparent force known as the Coriolis force. This deflects the direction of the wind to the right in the northern hemisphere and to the left in the southern hemisphere.

Detailed explanation-3: -The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect-a force that results from the rotation of the Earth-deflects them. The currents then bend to the right, heading north.

Detailed explanation-4: -The force, called the “Coriolis effect, ” causes the direction of winds and ocean currents to be deflected. In the Northern Hemisphere, wind and currents are deflected toward the right, in the Southern Hemisphere they are deflected to the left.

Detailed explanation-5: -The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars. Winds in the upper levels will blow clockwise around areas of high pressure and counterclockwise around areas of low pressure.
