Geography [1 Mark Question Answer]

The factors responsible for ocean currents are the rotation of the earth, the difference in salinity, temperature, and the prevailing winds.

Salinity is the amount of sodium in the oceanic water. It is 35%.

By meeting the warm and cold currents, a large amount of fog is created, which controls the temperature conditions in the fishing regions of the meeting grounds.

The Gulf Stream is a powerful warm ocean current affecting the climate of the eastern coast of North America and the western coast of Europe and it is an important source of tidal energy.

Tides are mainly caused by the centrifugal and centripetal forces of the earth and the moon.

Tides are the rise and fall of seawater due to the gravitational forces of the sun and the moon.

High temperature near the equatorial belt and landlocked seas lead to higher salinity or higher density of ocean water.

The North Atlantic Drift: It is the eastern extension of Gulf Stream to Europe as a warm current.

The Pacific coast of North America affected by the warm Kuroshio current are the famous fishing grounds of salmon fish mainly shared by Canada.

The Western coast of Norway is not frozen in winter due to the warm effect of Gulf Stream or the North Atlantic Drift touching the coast.

Due to the cooling effect of Labrador current keeps these coasts comparatively cold.
