Our Earth:Some interesting questions and answers

ByJames Ron Leigh

Usually printed in 3 - 5 business days
Here is an informally presented collection of questions and answers, all related to Our Earth. Why do we always see the same man-in-the-moon face? At the coast, how far you should be able to see? Still at the coast, you look at the times of high tides. You notice that there are two high tides every 24 hours. The sun exerts a huge gravitational pull on earth, far greater than that from the moon, so why is the moon the main raiser of tides? How far below your feet is sea-level when you are on top of Mount Everest, 29035 feet (8850 metres) above sea level. Above which sea level is it measured? Other topics include: •Why do you weigh less on the equator than at the North Pole ? •Why are there TWO tides per day, although the moon passes overhead only once per 24 hours ? •Why does the moon always show the same face to us? •How do sundials work ? In this concise book, twenty topics that might already have intrigued you are discussed and explained in simple terms.
