Why does the length of day and night change with the seasons?

Answer 1

Because the earth is tilted at 23.5° and as it orbits the sun different parts of the earth are nearer to the sun, making it seem higher in the sky or lower in the sky. The closer you are to the the equator, the less of a difference there is in the length of the day throughout the year. By the December 21st, the northern hemisphere is tilted as far away as it can be, making the days shortest in the northern hemisphere and longest in the southern hemisphere. by June 21st, the northern hemisphere is tilted at the maximum towards the sun and the longest days are in the northern hemisphere.

Answer 2

The length of the daylight changes during the year because of Earth's tilt.

As the Earth orbits the sun, its tilt causes the northern and southern hemispheres to alternate between greater and lesser exposure to the sun.

As a hemisphere is tilted away from the sun, the length of a day becomes shorter. As it is tilted toward the sun, day lengths become longer.

The further you are from the equator (the higher your latitude) in either hemisphere, the more pronounced the effect. At the north and south poles there is a period each year when the sun does not set at all, and a period when it does not rise.

As the earth goes round the sun once a year, and it's at an angle, half the year the northern hemisphere is pointed towards the sun, and half the year the Southern Hemisphere is. If you lived on the equator you'd get much less change than if you lived on the north pole.

When a hemisphere is pointed towards the sun, more of it gets light, and thus in a given day more light is seen by any place on that hemisphere. The earth turns once every 24 hours, but the number of daylight hours a place gets during that time is determined by how far north or south it is, and where exactly the earth is in relation to the sun.

This is why Australians can have Christmas in summer! That's exactly it for people that don't know

Answer 3

In the summertime, days are the longest, and in the wintertime they are the shortest. It all has to do with the Earth's rotation around the sun. One side is angled closer, we feel the sunshine longer and thus we have summer. And of course the opposite is true for winter. Hope that helps :)

Answer 4

The length of night and day may very but, on the fall and spring equinox the length of night and day are equal. The day is 12 hours and night is also 12 hours long. In the winter the days are shorter and the nights are longer. In the summer that is different. The days are longer and the nights are shorter. So the length of night and day change everyday throughout the year. After the summer equinox the days slowly start to shorten and the night slowly grows. After the winter equinox the days slowly start to grow and the nights start to shorten slowly.

Answer 5

The earths tilt makes the sun get lower in the winter and taller in the summer. In the orbit of the sun the north hemisphere has different seasons then the south hemisphere.

Answer 6

Because it wants too is that so hard? <--- stupid? The Earth is at a tilt ths causes it to fall in and out of the suns light and heat.
