The Hottest and Coldest place on Earth

I've read an interesting fact from a small article in a science magazine and this person asked a scientist where is the hottest and coldest place on Earth and here's an extract:
"The most frigid spot know on earth’s surface is at the Vostok Ice station in Antarctica, where in 1989 the temperature hit -128.6 Fahrenheit. It was so cold that when scientists there poured water from the kettle, the water froze before it hit the ground. At the other extreme is El Azizia, Libya, where the hottest temperature recorded was 136 Fahrenheit in Sept 1922. High in the atmosphere or deep underground, temperatures are even more extreme. In the noctilucent clouds that form 50 miles above the north and south poles, temperature fall to as low as –220 Fahrenheit. And in the Earth’s solid iron core, 4000 miles beneath us, temp may reach 13,000 F hotter than the surface of the sun." Cool.
