The climate in the polar regions is the result of a self-reinforcing process. Because so little solar energy is received, the water freezes to ice, which then, like a mirror, reflects the small amount of radiation that does arrive. A multi-layered, complex wind system, which plays a decisive part in the weather and climate on our planet, is driven by differences in temperature and pressure between the warm and icy regions.
It is warmer near the equator because sunlight hits Earth's surface most directly near the equator. Near the poles, sunlight arrives at a steep angle, so it must spread out over a greater area. Earth has seasons because the Earth's axis is tilted as it revolves around the sun
