The term used to describe how to measure how reflective the surface is, is the surface albedo. Surface albedo represents the ratio of irradiance reflected to the irradiance recieved by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of a solar radiation reaching the Earth's surface.
The poles receive more direct sunshine so it has to do with the angle that the light hits. The Earth is round and when light hits it the light wraps around the earth. At the poles the light is very stretched and at the equator it is very direct hence it is hotter at the poles.
