There is more sunshine at the equator than at the poles. At the equator, the sun stands overhead, while in the polar regions it always makes an angle with the zenith, so the absorbed radiation energy per square metre is lower than at the equator. Furthermore, the sun does not shine (does not come above the horizon) for at least one day a year north of the Polar Circle (or south of the Polar |Circle in the Southern Hemisphere). The number of days with no sun above the horizon increases towards the poles to 182.

The Frigid Zone experiences colder temperatures compared to other zones due to the inclination of the earth's axis, which results in the area receiving oblique rays of sunlight during the winter. The coldest zone of the Earth is known as the Frigid Zone. It receives very less heat because the rays of the Sun are very slanted here. The North Frigid Zone lies between the Arctic Circle and the North Pole, while the South Frigid Zone lies between the Antarctic Circle and the South Pole. Because it is the farthest from the equator, the Frigid Zone is the coldest zone and because of the nearness to the equator, the Torrid Zone is the hottest zone. Complete Answer: Geographical zones include the five primary latitude regions of the surface of the Earth, separated by the major latitude circles. Due to the spherical shape of the Earth, sunlight falls on different parts at different angles. Direct and focused sun rays falls on the equator and hence, the regions here are hotter and warmer. The Polar Regions receive diffused sun rays, which is why the areas there are colder.The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles. An explanation for why Polar Regions are colder than equatorial regions is that: Sunlight strikes the Polar Regions at an angle and spreads out over a much larger area. Because the Earth is nearly round, the equator receives direct light, and the poles receive slanted light, with a gradation in between. Due to the differential heating of the Earth's surface (unequal heating of all regions), it is always warmer at the equator than at the poles.
