The atmosphere is
extremely thin here. The
upper part of this layer is
the beginning of true
space. Some manmade
satellites orbit the Earth
within this layer.
The air is very thin here,
but very hot – thousands
of degrees hot! It is
heated by the Sun’s
energy. Both the space
shuttle and the
International Space
Station orbit in the
middle-to-upper part of
this layer. Also, the
Aurora Borealis (northern
lights) occurs in this layer.
This is the coldest layer.
Temperatures are as low
o o as -90 C (-130 F).
Although the air is thin, it
is still thick enough to
burn up meteors
escribe why there are different layers in the atmosphere what are the charecterestics of them which one has the ozone layer which layer is the coldest which is the hottest which one holds the aurora borealis
