Suppose the earth began to rotate twice as fast what will happen?

Answer 1

- Days would be 12 hours long instead of 24 hours.

- Light and dark would each be nominally 6 hours long instead of 12 hours.

- Instead of staying up for 12 hours and then relaxing for 12 hours as we do now,

I think the same evolutionary influences of defense from predators and visually

finding our way around would still have synchronized us with light and dark, and

we would work for 4 hours, sleep for 4 hours, and drink beer and go to movies for

the other 4 hours, every day.

- I'm not sure what caused our feeding cycle to be what it is. If the Earth spun

twice as fast, we might have a system where our meals are 2 hours apart during

our waking time instead instead of 4 hours. Or, if that was taking too much time

away from all the other things we had to get done during a day, then we might be

on a system of only 2 meals a day, like many of our animals are now. Either way,

my dogs would probably expect their bowls to be full every 6 hours instead of

every 12 hours.

- As you can tell, I'm a little thin on the biological aspects. I'm wondering whether

all this frantic activity, like only getting 2 hours to let a meal settle, and going to bed,

getting up, bathing and shaving every 12 hours, might wear us out sooner, and there

might be fewer years in our normal human lifetime.

- High- and low-pressure weather systems would spin faster, and

there would be more wind on Earth.

- The moon would take about 54.6 days to orbit around Earth instead of 27.3 days.

- The moon would take about 59.1 days to go through all its phases instead of 29.5 days.

- Each season would be about 180 days instead of 90 days.

- There would be about 7301/2 days in a year.

- I think we would need a Leap Year every other year instead of every 4 years.

- If we still wanted our months to roughly match the motions of the moon, then

we would need calendars with 56 to 62 days in each month, but we could still

get along with only 12 months.

- High- and low-tides would come 3 hours apart instead of 6 hours apart.

Answer 2

All stalagmites and stalagtites will break off, The East coasts of the Americas and Asia will be flooded, the Great Barrier Reef might well disintegrate and watch out for those winds...

Answer 3

day would be over sooner

Answer 4

No.
