What factors contribute to the uneven heating of the earth by the sun?

Answer 1

Earth has a tilted axis. As the Earth revolves around the sun, either the Northern or Southern Hemisphere is aimed more directly at the sun. This means a higher consentration and thus, insolation (see insolation).

Answer 2

We have several factors to consider here. First, the earth spins on its axis once every 24 hours, bringing us day and night. Logically, during the day, the sun is shining on the surface and the earth is heated. At night, the sun is not shining on the surface and the earth cools. Thus, we have daily changes in the amount of light reaching surface, resulting in daily changes in the amount of heat reaching the surface. Second, because the earth is a globe, the sun's rays strike the surface of the earth at the equator more directly than at the polar regions resulting in differences in the amount of light reaching the surface of the earth, and hence, the equator heats up more quickly than the polar regions. Third, the earth's axis is slightly tilted, and the tilt of the axis combined with the revolution around the sun each year, brings seasonal changes in the amount of sunlight striking the surface of the earth. For example, when the Northern Hemisphere is at a point in our revolution around the sun where it is tilted towards the sun, the rays fall more directly on the surface bringing summer temperatures. Six months later, the revolution around the sun brings earth to a point where the Northern Hemisphere is tilted away from the sun; the rays fall less directly on the surface causing cooler, winter temperatures. .
