The tropics always receive intense direct sunshine, The poles receive little or no sunlight, during summer and winter, respectively. If you point a flashlight directly down the light is concentrated in a circle but if you shine it at an angle with the floor the same amount of light (photons) is spread out in a long elipse over a larger area providing less "heat" (photons) per square yard (of earth). The poles spread out the available light. The poles can warm up during their summers because the sun shines 24 hours a day but not very high in the sky. Fortunately enough heat to melt the ice caps is not available and the white ice and snow reflect the meager heat into space.

Even when the World tilts on it's axis, the Equator still remains closer to the Sun than the Poles do and the Tropics are therefore warmer

The tropics tend to be on the Equator, this is closer to the sun than the poles and so receives more direct sunlight and therfore is a hotter region.

The tropics are closer to the equator, than they are to the poles.

the tropics are closer to the equator, where the poles are at each end of the earth, where sunlight is at its furthest, this never alters due to the earths acssis.

Because of the angle that sunlight hits at each place. At the equator it's roughly 90º, while at the pole it's much, much less.

Sunlight strikes the earth at a steeper angle there and hence delivers more energy to the earth's surface.
