Atmospheric Gases

If this layer is too thin, UV radiation from the sun would reach earth and could destroy or damage plant and animal cells.

• carbon dioxide

• ozone

• oxygen

If we have too much of this gas, we won't get enough UV radiation to make vitamin D. This means that we wouldn't have strong bones and our bones would break easily.

• ozone

• oxygen

• carbon dioxide

• ozone

• oxygen

If the concentration of this gas is too high, there's a danger that things can spontaneously burst into flames.

• carbon dioxide

• ozone

• oxygen

If the amount of this gas continues to increase, Earth might become too hot to live on.
