ATMOSPHERE
The earth’s atmosphere is a mystery to me,
And no life on this planet would there ever be,
If we did not have this awesome, magical and gaseous shield,
A burnt wasteland would there be, rather than a beautiful field.
Earth’s atmosphere goes up for many miles,
Which causes air pressure like molecules in a pile.
At sea level, you have the most molecules of air.
As you go higher up, air molecules become more spare.
The atmosphere protects us from radiation(1)
and meteorites.
Thank heavens for this or a lifeless planet would be our plight.
Nitrogen and oxygen(2) are the two
main gases in which the atmosphere is comprised.
Scientists are still not exactly sure how the atmosphere formed
so they must theorize.
Weather is generally caused by temperature and pressure change,
Occurring ten to twenty kilometers from the surface do these
forces range
The earth’s atmosphere was formed as the earth cooled.
There was as yet no life and no humans around to rule.
Slowly plants came around and using carbon dioxide gas,
Fortunately had no use for the oxygen part and let it pass.
Breathe in that waste product which is given off by plants.
It’s called free oxygen, and life to animals does it freely
grant.
Now exhale, and comes from your lungs carbon dioxide gas,
Which plants use in photosynthesis, just like the outside grass
To produce the energy it needs to make its very own food,
Working along with water and sunlight, how clever and shrewd.
It’s a circular relationship, opposite but can you also
relate,
How one depends on the other, nature’s plan and our fate.
1: Radiation-Energy transmitted by waves through space.
2: Nitrogen and Oxygen-The atmosphere is about 75% nitrogen
and about 20% oxygen. It also contains water vapor, ozone, neon, helium, carbon dioxide, argon, methane krypton, and nitrous
oxide, all in tiny amounts. (With the exception of water vapor.)
