उत्तर
During summer the North Pole continues to slant more towards the sun. Because of the tilt, it exposes a larger areas to sunshine. The Northern Hemisphere in this case has longer days and shorter nights. On 22 June, North Pole slants most towards the Sun, this is the longest day (the Summer Solstice) in Northern Hemisphere. The situation is exactly the opposite in Southern Hemisphere. On 22nd December is remains tilted most towards the Sun. So the days are longer and nights are shorter in the Southern Summer which is opposite of Northern Winter.
