If the Earth's period of rotation became faster how would it affect the # of hours of daylight? Why?

Answer 1

I don't understand what you mean by the period of rotation becoming faster. Period is measured in units of time. For example, how long it takes for one rotation. Faster implies a greater speed or rpm. Saying a faster period makes no sense.

Anyhow, changing the earths rotation speed would have no affect on the number of hours of daylight. A faster rotation would mean shorter days (by days I mean the time that the sun is up). But the length of the night would be shortened by the same factor. So, the next day will arrive sooner. It will all average out to be the same in the end.

Oh, and this is all assuming you continue to use our current definition of a day. If you change the definition of a day to match the new rotation speed then you WILL have fewer hours of daylight in each day. But that will be because you redefined the day not because the rotation rate changed.

Answer 2

If Earth's rotation period were to speed up, it would depend on how much faster it sped up on how much of a difference in made in daylight hours. For example, at the equator there is equal amounts of daylight and darkness. There is 12 hours of each totaling to a 24 hour day. The true rotation of the Earth is 23 hours 56 minutes and 4 seconds--this is why we have daylight savings time and leap years (which has to do more with orbital period than rotation). Over time during the summer, the days get longer. BUT back to the equator example. If the day was cut in half so that there were only 12 hours a day. There would technically be only 6 hours of daylight and 6 hours of darkness at the equator. If you knew the true hours of day and night in the location you are talking about and how much the 24 hour day is cut then you could figure it out for that area.

It would change the hours of daylight because the Earth will be spinning faster on its axis, which means any one fixed point will pass by faster....which means less day light!

Answer 3

You would have less hours in the day and night the time change would not be the same between day or night .using a percentage formula you could figure out how much time difference between day and night. for example if the earth moved 10 percent faster you would lose 10 percent of the night and 10 percent of the day. if you are not on the equator there is a difference in daylight time and night time (time).if you are on the equator their would be equal time change between the two.

Answer 4

The length of the day would be cut shorter so it would be less than 24 hrs. This happens because if the Earth spins faster, it makes it take less time for the Earth to rotate one full rotation and the time that it is dark and the time that it is light out would be decreased.

Answer 5

well the earth is 24,000 miles in diameter and spins at bout 989 miles an hr well that equals the 23 hrs and 56 minutes in a day andif u sped that up the days wood go faster do to day light is controlled by how fast earth spins

Answer 6

Probably would have no effect on the number of hours because we would simply reduce the length of an hour so as to keep 24 hours in a day.

Answer 7

It would affect it in that daylight would be less per day but it would average out over two days.
