The change between day and night is caused by the rotation of the Earth on its axis. ... The changing lengths of days and nights depends on where you are on Earth and the time of year. Also, daylight hours are affected by the tilt of the Earth's axis and its path around the sun.

Why is the length of day and night different?
Rotation of the Earth causes night and day to alternate. Since we learned that the Earth's axis is tilted and hence the equator is not facing the Sun directly, different places on Earth would experience unequal length of days and nights—not exactly 12 hours of day and 12 hours of night all the time.
What causes longer day and shorter night?
Northern Hemisphere dwellers, or most of the Earth's population, have probably all noticed longer days and shorter nights in the summer and the opposite in winter. This phenomenon occurs because the Earth's axis is not straight up and down at a 90 degree angle, but it is instead tilted a bit.
What causes variations in the length of daytime?
The correct answer is revolution of the earth on tilted axis. The number of hours of daylight, i.e. day length, on any particular day of the year differs from place to place. ... As we know, day and night are the consequence of the earth's rotation on its axis. But, the axis is tilted 23.5 degrees.
How is the length of the day and night during that time?
It takes 24 hours for the Earth to turn all the way around (rotation). That makes one day and one night. At any moment, half of the world is in daytime and half is in nighttime.
What causes day and night rotation or revolution?
Each planet rotates, or spins, on its axis. The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. ... Because of this direction of rotation, we see the sun rising every day in the east and setting in the west.
Why is December 21 so important?
In the Northern Hemisphere, December 21 is often the shortest day of the year and is sometimes regarded as the first day of winter. In the Southern Hemisphere, December 21 is often the longest day of the year and occurs during the southern summer.
Is it shorter days and longer nights 2021?
Meanwhile, the Southern Hemisphere is having short nights and long days. The 2021 December solstice moment – when the sun reaches its southernmost point in the sky – will happen on Tuesday, December 21, 2021, at 15:59 UTC (9:59 a.m. CST; translate UTC to your time). ... It shows the path of the sun during that time period.
Which country has 24 hours daylight?
76 days of midnight sun between May and July greets travelers in Northern Norway. The further north you go, the more nights of midnight sun you get. During the summer months, you can experience up to 24 hours of sunlight above the Arctic Circle, which means more time to enjoy the sights and make new discoveries.
What are the causes of variation of sunlight at different places?
The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation. Places that get more solar energy have more heat.
What are the causes of variation of sunlight at different places Class 9?
The variation in duration of sunlight at different places is due to differences in latitude, altitude, season and duration of the day.
What causes twilight and dawn?
Twilight and dawn are caused because of 'scattering of sunlight' off the atmosphere. Twilight and dawn are periods when little light is visible in the sky. EXPLANATION: Twilight is time period between sunrise and dawn or between sunset and dusk.
What causes day and night Upsc?
Days and nights occur due to rotation of the earth. The circle that divides the day from night on the globe is called the circle of illumination. Earth rotates on a tilted axis. Earth's rotational axis makes an angle of 23.5° with the normal i.e. it makes an angle of 66.5° with the orbital plane.
How are seasons caused?
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. ... Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun.
What are the causes of rotation?
Earth rotates because Sun attracts the earth and thus pulls earth towards it secondly due to earths revolution around sun it tends to go away from sun in direction of the tangent hence a rotational force (torque) acts on earth and it tends to rotate.
