what would happen to the amount of insolation the earth recieves if the earth's rotation was twice as fast?

Answer 1

No change at all. Rotation is irrelevant to insolation

Answer 2

If the earth was rotating twice as fast we would have shorter days and nights, about 6 hours each. Total insolation not affected.

Answer 3

Well, the reason winds blow approximately parallel to isobars is because the Earth rotates.Near the equator you only get weak wind systems that are short-lived, because the Earth's surface there is almost parallel to the axis of rotation. My guess is that if Earth's rotation was faster, you'd get stronger winds round high and low pressure systems and these systems would last longer. This wouldn't make much difference to anticyclones because winds around them are light and weather in the middle is clear. But you'd get more strong long-lasting tropical storms and mid-latitude depressions, so I'd guess you'd get more cloud cover.

Answer 4

It did rotate swifter some time past. The day became purely extremely longer than 6 hours long by capacity of standardized time quickly after the the Earth became formed (in all likelihood after the effect that resulted interior the formation of Moon.) throughout the Devonian era, the day became something like 18 hours and 18 to 22 minutes long. there is fossil information for this. some sea creatures make a layer of aragonite on the interior of their shells on a daily basis. the a number of layers could be dated by capacity of examining the share of O sixteen ions to O18 18 ions in each layer of aragonite, alongside with any radioactive make certain and daughter isotopes which have been given included into the aragonite crystals on the time they formed. whilst aragonite is placed under adequate stress (from overlying sediments), aragonite crystals cave in into extra good calcite crystals.

Answer 5

The effect of the insolation would be more evenly distributed; ie, high temps would be lower and low temps higher.
