Let’s Begin…
Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special? Brian Jones details the dizzyingly wide array of ways that spinning affects our lives.
Billions of years ago, the spin of the Earth was much faster than it is now; in the time of the dinosaurs, the day was much less than 24 hours long. Suppose the earth spun twice as fast, so a day was 12 hours long. What changes would this make in the Earth’s weather?
