Question

1 . The atmosphere is made of a mixture of gases , mostly [blank_start]nitrogen[blank_end] and [blank_start]oxygen[blank_end] that wrap around the planet .

2 . Those gases [blank_start]protect[blank_end] us by blocking out dangerous rays from the sun .

3 . The earth's atmosphere has five layers .
- [blank_start]Tropo[blank_end]sphere
[blank_start]- Strato[blank_end]sphere
- [blank_start]Meso[blank_end]sphere
- [blank_start]Thermo[blank_end]sphere
- [blank_start]Exo[blank_end]sphere

4 . Gases become [blank_start]thinner[blank_end] the higher up you go .

5 . The troposphere is the lower layer . The troposphere is known as the [blank_start]weather[blank_end] layer .

6 . Above the troposphere is the stratosphere , where temperatures [blank_start]increase[blank_end] with altitude .

7 . The stratosphere goes from - 60 C at the bottom and warms to about 32 ( 0 C ) at the top . This happens because the stratosphere is heat from above by the sun's [blank_start]solar[blank_end] [blank_start]radiation[blank_end] .

8 . The [blank_start]ozone[blank_end] layer is also found in the stratosphere . Ozone is a gas that absorbs harmful [blank_start]UV[blank_end] rays and protects us from too much solar radiation .

9 . The atmosphere reaches its coldest temperature of - 90 C in the [blank_start]mesosphere[blank_end] .

10 . The Thermosphere is the [blank_start]warmest[blank_end] layer of the atmosphere . The air so thin that not much solar radiation can be absorbed and temperatures climb to almost [blank_start]2000[blank_end] C .

11 . The sky is blue because the gases in our atmosphere [blank_start]reflect[blank_end] blue light making the sky appear as such.
