The atmosphere is made of a mixture of gases , mostly and that wrap around the planet . 2 . Those gases us by blocking out dangerous rays from the sun . 3 . The earth's atmosphere has layers . - - - - - 4 . Gases become the higher up you go . 5 . The troposphere is the layer . The troposphere is known as the layer . 6 . Above the troposphere is the , where temperatures with altitude . 7 . The stratosphere goes from - 60 C at the bottom and warms to about ( 0 C ) at the top . This happens because the stratosphere is heat from above by the sun's radiation . 8 . The is also found in the stratosphere . Ozone is a that absorbs harmful rays and protects us from too much solar radiation . 9 . The atmosphere reaches its temperature of - 90 C in the . 10 . The is the layer of the atmosphere . The air so that not much solar radiation can be absorbed and temperatures climb to almost 2000 C . 11 . The sky is blue because the gases in our atmosphere blue light and it appears to be .
