Lucky's life has always been about skiing. World slalom champion and long-time coach, he will give you hands-on advice and make you a skiing pro! Improve your skiing with me at my private training site in Central Florida. I concentrate on teaching techniques that can be used long after you have left here, so that you can continue to improve on your own.
The lowest layer of Earth's atmosphere is called the troposphere, which begins at the surface and extends to an average altitude about 17 to 20 kilometers (55,000 to 65,000 fe â¦ et).
The mesosphere is a layer of Earth's atmosphere. The mesosphere is above the stratosphere layer. The layer above the mesosphere is called the thermosphere. The mesosphere starts at 50 km (31 miles) above Earth's surface and goes up to 85 km (53 miles) high. As you get higher up in the mesosphere, the temperature gets colder. The top of the mesosphere is the coldest part of Earth's atmosphere. The temperature there is around -90Â° C (-130Â° F)! The boundaries between layers in the atmosphere have special names. The mesopause is the boundary between the mesosphere and the thermosphere above it.
