What planet has the greatest similarity between the length of its day and the length of its year?
Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.
How earth tilts and orbit causes season and how it effects day length?
Earth's tilt at the 23.5 causes unequal temperatures depending on were the earth is in its orbit around the sun. Because of the tilt when it's winter for the northern hemisphere, it is summer down in the southern hemisphere. When it is spring for the north, it is fall in the south and so on. Earth's tilt does not rotate as the earth does. So when the Solstices happen (depending on where you live, northern or southern) creates the longest day and longest nights or it will create the shortest day and the longest night. The equinox's that happen in spring and fall are the only days that both day and night are the same(ish).
Is the length of the day the factor that governs the seasons?
The length of the day is not the reason but is a result of the season. The reason for seasons to take place is the inequality of distance between sun and earth with time. We all know that earth rotates around sun. But it won't rotate in a perfect circular path. The orbit of earth is an oval in shape. Hence, some times it will be closer to sun and some times farther. When it is closer, most of the area on earth is covered by sun. Hence, we have more day time (or length of the day) during summer. In a similar manner, as less area is covered by sun, the length of the day is less in winter.
How does gravity affect length of day?
It doesn't. For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
How do sloes and equinoxes relate with seasons?
An equinox is the time when the day and night are of equal length in a day. It is also the time that the Sun is directly overhead at Earth's equator at noon. A solstice is the time when the day and night are the most different in length of time than any other time of the year. It is also the time that the Sun is farthest from being directly above the Earth's equator at noon.
What would happen to the length of the day if you had no atmosphere?
Nothing - the length of 'day' on any planet - is the time it takes to revolve once on its axis. Relating to the Earth - that's approximately 23 hours 56 minutes.
What would happen to the length of the day if earth took 40 hours to rotate?
In that case, the length of the day would also be approximately 40 hours.
What would happen to the length of a day if the rotations sped up?
It takes 24 hours (the length of one day) for the Earth to rotate once. If the rotation sped up, the length of a day would shorten.
What is the length of day on earth?
the length of day on earth is 24 hours
If there were no atmosphere what will happen to length of day?
Sunlight bounces around in the atmosphere, extending the length of the day both in the morning (before sunrise) and after sunset, roughly 30 minutes or so. Without an atmosphere it would be pitch black as soon as the sun set far enough for light to extinguish from any mountain slope eastward of you--the total day would be about an hour shorter.
What would happen if the time of the earth's rotation were different from what it is?
A day would be a different length than 24 hours.
What planet's length of its day is close to the length of Earth's day?
Mars
Difference between Mars and earth?
Mars is a cold, dry planet with a thin atmosphere, while Earth has a moderate climate, liquid water, and a thick atmosphere. Earth has a diverse range of life forms, while Mars has no known life. The length of a day on Mars is slightly longer than a day on Earth.
What is the length of days does earth have?
The earth day is Approximately 24 hours in Length.
What is the length of on day on the moon?
The length of a "day" on the moon is 29 Earth days.
Is earth day the same around the world?
If you mean the length of the day, yes - that is the same around the Earth. The Earth rotates as a rigid body. If by day length you mean hours of sunlight. On the same lines of latitude day length will be the same, but due to the wobble in the rotation of the earth, day length is different along lines of longitude.
What controls the length of a day?
The length of a day is primarily controlled by the rotation of the Earth on its axis. The Earth takes approximately 24 hours to complete one full rotation, which determines the length of a day. Variations in the Earth's rotation speed can result in minor changes in the length of a day.
