Which statement correctly describes the chemical makeup of Earth's atmosphere?

• oxygen is present in larger quantities than nitrogen

• argon is the least abundant gas in the atmosphere

• water vapor is the most abundant gas in the atmosphere

• carbon dioxide is present in trace amounts compared to nitrogen

Which gas is the most abundant gas in Earth's atmosphere?

• carbon dioxide

• nitrogen

• oxygen

• water vapor

Which trait is common in gases that contribute to Earth's greenhouse effect?

• the ability to trap heat

• a tendency to lose electrons

• a tendency to exist as diatomic molecules

• the ability to bond with multiple other elements

Some research has shown that the burning of fossil fuels contributes to an effect called global warming, which scientists believe is changing the chemical makeup of Earth's atmosphere. Use of which invention would help lower this effect?

• electric car

• digital camera

• high-speed internet

• battery-powered radio
