Temperatures and Seasons
The relationship between temperatures and seasons forms a sinusoidal graph because the function never stops and will continues to go on during the lifetime of the earth. They are tightly connected to each other because of how the earth and the sun are positioned. We all know that the earth rotates around the sun for 365 days in a cycle, and the tilted angle (23.5 degrees) earth make the concentration of sun radiation varies on the surface of the earth, by any means the phenomenon creates four seasons on earth. Seasons are basically the different changes between temperatures, and because the earth is titled the south and north hemisphere received different amount of sunlight during each season. The area where the radiation is concentrated on would experience summer and at the same time the other hemisphere would experience winter because the same amount of sunlight that is distributed on a huger area of the surface, so the energy gets weaker.
