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.
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
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 :)
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.
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.

What is autumnal equinox length of day?
During the two equinoxes in spring and fall, the days and nights are of equal length. This is because of the position of the earth in its orbit around the sun.
Does the equinoxes occur during summer and winter?
There is no such things as summer and winter equinoxes. You have spring and autumn equinoxes, when the amount of daylight and darkness are equal. In summer and winter you have solstices, when you have the longest and shortest days in terms of the amount of daylight. The equinoxes are when the Equator transits the Ecliptic making the Sun appear as if it is moving either North or South depending on what part of the Ecliptic the Earth is in relative to it's rotation around the Sun. March and September. Called the Spring and Autumn equinoxes and when one hemisphere is in the Spring Equinox, the other is in the Autumn Equinox. Same point on the Ecliptic. "Beware the Ides of March."
Where does a crime laboratory analyst work?
a crime lab works during the day and the night !!!!!!!!!!!!!!!! a crime lab works during the day and the night !!!!!!!!!!!!!!!! a crime lab works during the day and the night !!!!!!!!!!!!!!!!
How do day and night appear explain?
In the day, the sun is up. In the night, the sun is down.It all has to do with the Earth's rotation
What is the purpose of leap day?
keep the calenders ans seasons in sequence over the centuries
What if the earth wasent tilted?
There would be no seasons, and no change in the length of day and night, anywhere on Earth.
Is NOT a direct result of Earth's rotation?
The change in seasons is not a direct result of Earth's rotation. Seasons are caused by Earth's axial tilt and its orbit around the Sun. Earth's rotation affects the length of a day and the creation of day and night, but not the change in seasons.
What will happen if the earth axis becomes vertical?
There would be no seasons, and the length of day & night would be exactly 12 hours each.
What are the results of revolution?
the different seasons and the length of day and night varies from place to place
What are the results Earth's revolution?
the different seasons and the length of day and night varies from place to place
When do the winter Daylight Saving Time begin in Hawaii?
Hawaii does not do Daylight Saving Time- it is so far South, that changing seasons makes little change to length of day/night.
Does the length of day and night stay the same during the year?
No, the length of day and night varies throughout the year due to the tilt of the Earth's axis as it orbits the sun. This results in the changing seasons and varying lengths of daylight and darkness.
When the seoson change some plants Respond to changes in what?
The length of day and night
What would happen to earth if it is flat?
No change in day or night, or any change in seasons, these occur because of Earth spherical property
How will the length of day and night change if the sun increases in size?
If the sun increases in size but nothing else changes, then there will be no change in the lengths of day and night. However, the gravitational and tidal effects of changes in the sun's size is likely to affect the earth's rotational period and its orbit.
What is the reltionship between day and night and seasons?
The relationship between day and night and seasons is that the length of daylight and darkness determines the changing of seasons. In areas where days are longer than nights, it is typically warmer, indicating summer. Conversely, when nights are longer than days, it is generally colder, signifying winter. The tilt of Earth's axis also plays a significant role in the changing seasons.
What is length of the day in a autumnal equinox?
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
