Space

2. This layer of the Atmosphere holds about 75% of earths gases and it has the most dense air.
5. A continent that is located below earth and it has really low tempature's and it is below the greatest Ozone hole
7. A type of gas that is damaging the earth's ozone layer and has chlorine in it.
10. A giant piece of rock that usually got pushed by a force outerspace and can sometimes land in planets harming living things or the planet itself.

13. A zone in the stratosphere made up of 3 gases that can react easily to any other gases and they all combine and make a force field that can trap highly extreme tempatures.
14. This layer of earth's Atmosphere is the furthest from earth and is outer space.
15. Layers of gases surrounding earths surface that make it livable for living things.
16. A machine made by humans that was invented to fly and it works with turbines and engines and rocket thrust and it is controlled by panels and flaps and usually can be used to transport goods or humans or even used for Aeriel combat.

1. This layer of the earth's Atmosphere is the coldest layer and is usually where asteroids burn up.
3. This layer of the earth's Atmosphere contains the ozone and is the same altitude aircraft fly in.
4. Weather is the tempature of a planet or when a natural event will occur.
6. A type of gas that any living thing needs to survive and breathe and it is made by plants or trees.
8. This layer of earth's Atmosphere is the hottest layer and this layer contains the northern/southern lights.
9. Damage in the ozone that is caused by other gases mixing up with the original gases of the ozone.
11. Machine made from Humans and it is used to view our earth from outerspace.
