Which of the
following statements about the gases in Earth’s atmosphere is NOT
true? a. | The largest percentage of gas in our current atmosphere
is nitrogen. | b. | Oxygen is the
second most common gas in our current atmosphere. | c. | Earth’s first atmosphere contained much more carbon dioxide than our
current atmosphere. | d. | All the gases in

Earth’s Atmosphere Surrounds Our
Planet | | | | |
How does the large presence of oxygen in Earth’s atmosphere provides
evidence that life exists here?a. | Because this gas is commonly released by volcanic
eruption | b. | Because this gas is the most common element in the
universe | c. | Because oxygen is released by living organisms called
plants | d. | Because this gas is released by living creatures called
animals |

The mixture of gases in Earth’s early
atmosphere contained much more carbon dioxide than our current atmosphere, and there was little
oxygen. Yet today’s atmosphere has about 22% oxygen.
Identify the process that altered the
mixture of gases in our atmosphere and increased the amount of oxygen.
a. | respiration from animals
(photosynthesis) | b. | volcanic venting
released millions of tons of carbon dioxide and water vapor in the air | c. | respiration from plants (photosynthesis) | d. | comets from space brought H2O (water) which released O (oxygen)
into the air |
|

|
Which gas in Earth’s atmosphere suggests
that there is life on Earth, and what evidence supports this?
a. | Oxygen, because this gas is released by plants which are
alive. | b. | Nitrogen, because this element is used to make
fertilizer for plants. | c. | Carbon dioxide,
because this gas is often released during volcanic eruptions. | d. | Hydrogen, because this is the most common element in the
universe. |

Millions of year’s ago, Earth’s
atmosphere was mostly carbon dioxide, water vapor, and ammonia.
Then photosynthesis significantly changed the
mixture of gases to form our current atmosphere.
Two-Part

the air. | b. | 1) sulfur from the atmosphere
2) release nitrogen into the air. | d. | 1) carbon dioxide
from the atmosphere
2) release oxygen into the
air. |
