The earth has three main climate zones because of the differences in latitude and distribution of sunlight.
Further Explanation:
The axis of the earth is tilt, due to which the sun strikes different region at different angle. The sun strikes the equator at almost vertical angle and maximum sunlight reaches the area around equator. The sunlight reaches the poles at a shallower anglethat is why they are coldest in comparison to the tropical region.
Justification for correct and incorrect
Amount of precipitation received: This option is incorrect.
The level of precipitation in the region determines the amount of rainfall the region will have.It occurs when a part of the atmosphere saturates with water vapor, and the water condenses and precipitates. If the region has higher precipitation then the level of rainfall will be high. It affects the climate of the region, not the whole earth.
Distribution of sunlight: This option is correct.
The axis of the earth is tilt, due to which the sun strikes different region at different angle. The sun strikes the equator at almost vertical angle, thus maximum sunlight reaches the area around equator. The sunlight reaches the poles at a shallower angle that is why they are coldest in comparison to the tropical region.
Ocean currents: This option is incorrect.
They are generated when the forces like the wind, the earth's rotation, gravitation of the moon, the salinity difference and temperature act upon the water. Thus, the current formation impact the climate of the region that are close to the oceans so, it does not influence the climate of the earth.
Prevailing winds: This option is incorrect.
The surface wind blows from a particular direction in a region is known as prevailing winds. Therefore, it does not divide earth into three different climate zone.
