Solar shock is the heat energy received by the sun's rays from the earth's surface and atmosphere.
Temperature is the amount of heat that the sun receives from the earth's surface and the atmosphere.
In the tropics the temperature stays high as the sun's rays are perpendicular to the temperature.
While in the polar, region, the temperature feels low as the sun's rays are diagonal.
The climate of a region can be determined from sun exposure and temperature whether it is hot, cold, even or uneven.
