Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What causes ocean currents in the Northern Hemisphere to curve to the right?
A
Earth’s orbit around the Sun
B
Earth’s spinning on its axis
C
Earth’s magnetic field
D
Earth’s force of gravity
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: -Circulating wind and ocean currents distribute energy and matter all around the globe. Surface currents are primarily driven by wind and Earth’s rotation. Earth’s rotation causes the pathway of both air and water to appear to curve rather than travel in a straight line. This is known as the Coriolis effect.

Detailed explanation-3: -The Earth’s rotation causes the ocean currents to turn in a process known as the Coriolis effect . Because of the Coriolis effect, ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Detailed explanation-4: -This apparent deflection is the Coriolis effect. Fluids traveling across large areas, such as air currents, are like the path of the ball. They appear to bend to the right in the Northern Hemisphere. The Coriolis effect behaves the opposite way in the Southern Hemisphere, where currents appear to bend to the left.

Detailed explanation-5: -The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere. The currents curve left in the Southern Hemisphere (Figure below). The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.
