Day and Night are caused by Earth's rotation on its axis.
Seasons are caused by the inclination of Earth's axis of spin to the plane of its orbit round the Sun and the progress of its orbit round the Sun.
-------------------------------------------------------------------------------
The earth's rotations cause day and night. The earth makes one complete rotation roughly every 24 hours. At any point in that rotation, an area of the globe is facing the sun. This is day. As the Earth continues to rotate, eventually this same point will rotate away from the sun. The absence of direct sunlight is what constitutes night.
The Earth's axis always remains pointing in the same direction as it revolves around the sun. As a result, the solar angle varies at a given place throughout the year. The variation in sun angle is the prime cause of our seasons.

∙ 10y agoThe lengths are all the same, but the earth is positioned differently because it rotates around the sun and it causes sunrise/sunset to be earlier or later depending on the time in the year.
Why do we have day and night?
We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles.
The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed.
How long does it take the Earth to turn around?
The Earth takes a whole day (24 hours) to makea complete turn.
Why is the Sun in the sky at some times and not at other times?
At any time half of the Earth faces the sun. This part has day. The other half of the Earth faces away from the Sun. It receives no light. It is dark and has night.
The sun is the source of light for day.
Why does the sun seem to move across the sky?
The Sun does not move. It seems to move across the sky starting in the east in the morning, moving toward the south at noon, and then toward the west as the day ends.
It is the Earth turning that makes it seem as though the Sun is moving.

When do the nights start drawing in?
Days start to get shorter after between Aug/Sept and longer in march/April
In which garden did Jesus fast for 40 days and nights before the last supper?
Jesus did not fast for 40 days and nights in a garden before the last supper. Jesus fasted 40 days in the desert/wilderness at the beginning of His ministry (Mark 1:12-13; Matt. 4:1-11; Luke 4:1-13). Jesus made His intercessory prayer (AFTER the Last Supper) in the garden of Gethsemane (John 14-18).
Why are there places on earth that experience polar days and polar nights?
i think because of the Earth's elliptical orbit, less sunlight reaches these places at the aphelion. =)
Earths length in days or years?
Earth days are normally rounded to about 24 hours, but in fact the time it takes for Earth to complete a full rotation (i.e. a day) is 23 hours, 56 minutes and 4 seconds. A year is approximately 365.24 days.
What would happen to both night and day if the earth took twice as long to spin on its axis?
Days and nights would be twice as long, obviously. The slower rotation would have impacts on the weather, much of which is driven by the Earth spinning. Days would be warmer and nights cooler, for example, because each spot on the Earth would have twice as long in the sunshine to heat up, with twice as long at night for heat to radiate away.
Can you predict seasons?
The seasons are already figured out . . . the seasons change on the equinoxes (days and nights of equal length) and on the soltices (days and nights are the most different in length)
How does the earths movement cause days and nights?
Because it tilts on its axis
What causes Earth''s rotation?
Days and nights, sunrises and sunsets.
What kind of seasons do they have in Alaska?
They have all 4 seasons, but due to its geographical location, both summer days and winter nights are long.
How will day and night be different if the earths axis was not tilted?
it would probably be the same nights and days
Which season has hot days and cold nights?
There are four different seasons. Fall is the season that has both hot and cold days.
What is the difference between the earth's rotation and the earths revolution. What causes the earth to have seasons. What causes the earth to have days and nights?
Those are three different questions; you would be better of asking them as three different questions on this site. The difference between rotation and revolution is that "rotation" refers to a movement of an object around its own axis; while "revolution" refers to a movement around an external object or axis - in this case, around the Sun.
Why do the longest days and nights occur?
They differ from the earths axis in relationship to its position during its one year revolution.
Does the rotating causes seasons?
No. Rotation (spin) causes days and nights. It is the tilt of the Earth as it revolves around the sun that causes the seasons, by changing the angle and duration of sunlight reaching areas of each hemisphere. Summer in the northern hemisphere is winter in the southern, and vice versa. Between these two extremes are spring and fall. Areas closer to the equator experience much less seasonal variation in daylight.

What is the measurement based on the earths orbit around the sun?
Tropical year from one spring to the next to govern seasons in 365.2422 days
How does the tilt of the earth affects the seasons and daylight length?
Our days are longer and our nights are shorter (more of the Northern Hemisphere is exposed to the light of the Sun for a longer period of time, creating the long days and shorter nights)
