The gas oxygen is necessary for living things. What evidence from the text supports this conclusion?

• Plants use carbon dioxide to make oxygen.

• Water vapor is nearly always present up to about 4% of the total volume.

• Oxygen is used by all living things and is essential for respiration.

• Nitrogen dilutes oxygen and prevents rapid burning at the Earth's surface.

Based on the text, what can you infer about how people can exist on Earth?

• People can exist on Earth because of tiny particles.

• People can exist on Earth because of moisture.

• People can exist on Earth because of outer space.

• People can exist on Earth because of its atmosphere.

What is the main idea of this text?

• Water vapor is almost always in Earth's atmosphere, but its contribution to the atmosphere's composition changes.

• Nitrogen is the most common gas in Earth's atmosphere, and its function is to dilute oxygen and prevent rapid burning.

• Earth's atmosphere extends many thousands of miles from Earth's surface, and it is held by Earth's gravitational pull.

• Earth's atmosphere is made of mostly nitrogen, oxygen, argon, carbon dioxide, and water vapor, and it is important for life on Earth.

What gas is most common in the Earth's atmosphere?

• Oxygen

• Carbon dioxide

• Nitrogen

• Argon

What is the role of carbon dioxide in the atmosphere?

• It is used in light bulbs and double-pane windows.

• It is used by all living things and is essential for respiration.

• It acts as a blanket that prevents the escape of heat into outer space.

• It dilutes oxygen and prevents rapid burning at the Earth's surface.

What percentage of the atmosphere can water vapor make up?

• Up to about 4%

• Up to about 6%

• Up to about 8%

• Up to about 2%

What is argon used for?

• To make proteins in living things

• In light bulbs, double-pane windows, and to preserve important documents

• In respiration by all living things

• To make oxygen through photosynthesis

How does nitrogen benefit the Earth's surface?

• By being used in light bulbs

• By contributing to the greenhouse effect

• By diluting oxygen and preventing rapid burning

• By acting as a blanket to keep the Earth warm
