What are the main two gases in the atmosphere?

• Nitrogen and Carbon Dioxide
• Nitrogen and Oxygen
• Oxygen and Helium
• Oxygen and Methane

Which gas makes up the largest percentage of the atmosphere?

• Nitrogen
• Oxygen
• Argon
• Carbon dioxide

What is the role of nitrogen-fixing bacteria in the soil?

• They convert nitrogen into oxygen
• They convert oxygen into nitrogen
• They convert nitrogen into a usable form for humans
• They convert carbon dioxide into nitrogen

How has the composition of the atmosphere changed over time?

• It has become richer in carbon dioxide and poorer in oxygen
• It has become richer in oxygen and poorer in carbon dioxide
• It has become richer in argon and poorer in nitrogen
• It has become richer in nitrogen and poorer in argon

What is the process of photosynthesis responsible for in relation to the atmosphere?

• Increasing atmospheric carbon dioxide levels
• Decreasing atmospheric oxygen levels
• Increasing atmospheric oxygen levels
• Decreasing atmospheric carbon dioxide levels

What is air pressure?

• The force that acts over a certain area
• The measure of the amount of oxygen in the atmosphere
• The measure of the amount of nitrogen in the atmosphere
• The force that causes gravity

Which tool is used to measure air pressure?

• Thermometer
• Barometer
• Hygrometer
• Anemometer

How does air pressure vary between sea level and mountainous regions?

• Air pressure is higher at sea level and lower in mountains
• Air pressure is lower at sea level and higher in mountains
• Air pressure remains constant regardless of elevation
• Air pressure is higher in mountains and lower at sea level

What is the primary source of atmospheric oxygen?

• Volcanic activity
• Algae and green plants
• Nitrogen-fixing bacteria
• Water vapor condensation

How does the presence of water vapor impact the composition of the atmosphere?

• It increases the levels of oxygen and decreases the levels of nitrogen
• It increases the levels of nitrogen and decreases the levels of oxygen
• It increases the levels of carbon dioxide and decreases the levels of oxygen
• It increases the levels of oxygen and decreases the levels of carbon dioxide
