Why don't all places on earth receive the same amount of direct sunlight at the same place?

Axial tilt of the earth and the rotation around the sun.

Explanation:

The rotation of the earth has profound impact on the climate and the weather patterns of the place as the Coriolis force plays a dominant role in the suns rays to reach the pars of the earth thus don't get the same type intensity as the wavelength are deflected and are narrower in the poles and the thus the tropics experience most of the sunshine. The temperate zones are thus classified as the zones of the mid-latitudes as the have temperature inversion and thus they experience the tropical and the temperate storms and the formation of the seasons is directly related to this. Hence the place on the earth have variation the patterns of the sun's rays that fall on them in the tropics, temperate and the polar zone a s one side faces the sun and the other side has night and similarly the northern side has summer in the month of June while the southern side has winter.

B. to study the spatial patterning of forests and forests fires and plan for better use of fire fighting resources in the u.s.

Don't depend on this but logically i think c
