Why do areas with low latitudes have warmer air than areas at high latitudes

Latitude denote the location of a place north or south of the equator. The reason why areas with low latitudes have warmer air than areas at high latitudes is the fact that different latitudes on Earth receive different amounts of sunlight. This defines the climate in the region.  So, areas at high latitudes  (farther away from the equator) have sharper angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. This is the reason why there the ar is colder.
