1

The oxygen we breath contains ______ ______ ____ bonded together

2 oxygen atoms

2

ozone molecule consists of

1 oxygen atom

3

ozone is ________ if we breath it

harmful

4

what does ozone do in the stratosphere and why is it important to us

protects life by absorbing harmful UV rays from the sun

5

stratospheric ozone is destroyed by man made and natural

pollutants

6

describe why lack of ozone is bad for life on earth

will give us UV rays, cancer, and global warming

7

we live in the

troposphere

8

list of layers of atmosphere, ground-up

troposphere, stratosphere, mesosphere, thermosphere, exosphere

9

How does temperature change in each layer
as altitude increases?

decrease in temperature = density of the air molecules

10

Oxygen molocule we breathe

o2

11

Oxygen molocule in ozone

o3

12

are regions in the stratosphere
where little ozone remains

ozone holes

13

ozone holes develop annually in the _____ regions

polar

14

____ ______ concentrate the ozone-destroying
chemicals in the polar region.

air currents

15

accelerate the reactions that destroy
ozone

ice particles

16

years where the polar ozone holes have grown larger

1980’s-2015

17

years where the polar ozone holes have begun to repair
with warmer winter temperatures and reduced
pollution

2016-2018

18

inject volcanic gases high
into the atmosphere.

explosive volcanic erruptions

19

One of these volcanic gases,____ _____, has an effect on
ozone.

sulfur dioxide

20

sulfur dioxide's _______ reflect some _____ _______ back into
space, causing the Earth’s surface to ____ — an effect
that typically lasts for _____.

aerosols, solar radiation, cool, years

21

also hasten the depletion of the ozone

aerosols

22

What happens to heat from the sun

Heat hits the ground and some bounces back

23

What do Greenhouse gases do?

They trap the heat that is bouncing back

24

What would happen if we didn’t have GHG?

The Earth’s average temperature would be below
freezing.

25

What happens if we have too much of the gasses?

The Earth’s temperature skyrockets!!

26

With just the right amount of gasses, the planet is ____ enough to
support life over most of its surface.

warm

27

What are the Greenhouse gases?

water vapor , carbon dioxide,
ozone, methane, and nitrous oxide.

28

(most important) ghs

water vapor

29

earths atmosphere is

0.04% carbon dioxide

30

Most of the carbon is trapped in _____ and _____ _______

rocks and organic
matter.
