Why doesn't water vapor contribute to Earth's rising temperatures despite trapping the most heat?

• It is not a greenhouse gas

• The atmosphere can only hold a limited amount, and excess falls as rain

• It is absorbed by plants

• It is converted into oxygen

What is the current average temperature of Earth with greenhouse gases?

• 0 degrees Fahrenheit

• 32 degrees Fahrenheit

• 59 degrees Fahrenheit

• 100 degrees Fahrenheit

How does water vapor help make Earth habitable?

• By reflecting sunlight

• By trapping about half the heat given off by Earth

• By absorbing carbon dioxide

• By cooling the atmosphere

What is the role of greenhouse gases in Earth's atmosphere?

• They cool the planet

• They trap heat and help maintain a habitable temperature

• They absorb oxygen

• They increase the amount of sunlight reaching Earth
