If the Earth spun faster,
one obvious change we would notice would be shorter days and nights.
If the Earth spun 100 mph faster than its current rate, our days
would only be 22 hours long. It would also be colder in the Eastern
and Western hemispheres, because these regions would have less time
to warm up with the sunlight. However, most changes would be noticed
around the Earth's equator. The equator is the fastest spinning
section of the Earth, rotating at a speed of 1,037 mph. Regions
further north, such as Chicago, rotate at a slower pace of 750 mph.
If the Earth's rotation increased by just 1 mph, the ocean levels
would rise about 2 inches, though it might take a few weeks to notice
this as the waters from the poles moved to the center. We would also
notice faster spinning hurricanes in this region, making them even
more powerful destructive forces. What else might happen at the
equator?
