once, that is what determines a day
First understand that night is caused when a point on a planet rotates with the planet so that it is not pointing towards the sun (it rotates into the shadow of its planet). When it is pointing towards the sun it is day!On Earth as the planet rotates once on its axis every 24 hours, a point on its surface will be in shadow for 12 hours at a time and in daylight for the other 12 hours.------------------------------------------------------------When the Earth spins around on its axis, it creates night and day on Earth. This movement makes it look like the Sun is moving across the sky. The Sun rises in the east and sets in the west, turning day into night.Most places on Earth have some amount of day and night every 24 hours. On Earth, the length of day and night usually changes with the seasons.When your location on Earth is facing toward the sun, it is day. When your location is facing away from the sun, it is night.Only the half of the rotating Earth that faces the Sun is illuminated at any given time.
because that is how long the earth takes to make 1 full rotation on its axis
True
Earth day lasts 24 hours! During those 24 hours you are supposed to turn your lights off for 1 hour!
On Earth, 24.
The earth makes a full rotation every 24 hours (a day).
An earth day is divided into 24 hours.
9.9259 hours Jupiter has the fastest rotation of any planet in the solar system.
As many as we might want if we ever start living there. Hours are made up by people.
27 hours
16 hours or 0.67125 earth days
Haumea makes a complete rotation in just 3.9155 hours, making its day very short compared to Earth's.
One earth day is 24 hours no matter where you are.
a complete rotation of earth on its axis takes about 24 hours, this is the length of a day.
The Earth makes a complete revolution about every 24 hours, giving us a day and a night.
24 hours.
