Which of the following is NOT considered a trace gas in the atmosphere?

• Carbon dioxide (CO₂)

• Methane (CH₄)

• Argon (Ar)

• Neon (Ne)

If the amount of nitrogen in the atmosphere decreased significantly, which gas would then make up the largest portion of the atmosphere?

• Oxygen

• Argon

• Carbon dioxide

• Methane

Based on the pie chart, which statement best describes the composition of Earth's atmosphere?

• Oxygen is the most abundant gas, followed by nitrogen.

• Nitrogen is the most abundant gas, followed by oxygen.

• Argon is the most abundant gas, followed by trace gases.

• Trace gases make up more than half of the atmosphere.

Which organisms are responsible for converting atmospheric nitrogen into a form usable by our bodies?

• Nitrogen-fixing bacteria

• Fungi

• Earthworms

• Insects

Explain how the formation of oceans contributed to the change in the composition of Earth's early atmosphere.

• Oceans increased volcanic activity, releasing more CO₂.

• Oceans absorbed water vapor, making the atmosphere drier.

• Oceans allowed CO₂ to dissolve, reducing its amount in the atmosphere.

• Oceans produced oxygen, increasing its concentration in the atmosphere.

Based on the information provided, why do scientists believe the composition of the atmosphere changed after the first billion years?

• Because volcanic activity stopped completely.

• Because the cooling of the planet led to the formation of oceans, which absorbed CO₂.

• Because the sun became hotter, burning off the atmosphere.

• Because plants started producing oxygen immediately.

A scientist wants to study how air pressure changes in different locations. Which instrument should they use and why?

• Thermometer, because it measures temperature.

• Barometer, because it measures air pressure.

• Anemometer, because it measures wind speed.

• Hygrometer, because it measures humidity.
