Amazing facts

1.Hottest place on Earth--
you might have guessed Death valley.True enough on many days. But El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured.But In Death Valley, it got up to 134 Fahrenheit on July 10, 1913.So, death valley could not become the hottest place on earth but El Azizia in libiya could become the hottest place on earth.
2.the coldest place around here?
Far and away, the coldest temperature ever measured on Earth is-129 Fahrenheit (-89 Celsius) at Vostok, Antarctica, on July 21, 1983. think of the coldest place of the earth. so you could now know both coldest and hottest place on earth.
3.Can rocks grow?
Yes,observing the process is less interesting than watching paint dry.It takes too much time so you can not observe it as you can your nail growth. Rocks called iron-manganese crusts grow on mountains under the sea. The crusts precipitate material slowly from seawater, growing about 1 millimeter every million years. Your fingernails grow about the same amount every two weeks. great amazing fact.
4.How much space dust falls to Earth each year?
Estimates vary, but the USGS says at least 1,000 million grams, or roughly 1,000 tons of material enters the atmosphere every year and makes its way to Earths surface. One group of scientists claims microbes rain down from space, too, and that extraterrestrial organisms are responsible for flu epidemics. There's been no proof of this, and I'm not holding my breath.It is one of the great amazing fact.

5.We can produce laser light a million times brighter than sunshine. believe or not but 60-65 million years ago dolphins and humans shared a common ancestor.
7.Polar Bears are nearly undetectable by infrared cameras, due to their transparent fur.
