The greenhouse effect maintains the Earth's temperature in a range that allows for life on Earth

• true

• false

What is changing the Earth's natural greenhouse effect?

• the release of oxygen

• human activity

• increase in plant life

• loss of the troposphere

burning fossil fules releases​ (a)   into the atmosphere

• carbon dioxide
• oxygen
• helium
• nitrogen
• sulfur dioxide

Additional carbon dioxide in the atmosphere leads to what/

• Enhanced plant growth and photosynthesis
• Global warming and climate change
• Decreased rainfall and drought
• Increased oxygen levels in the atmosphere

How does nasa monitor greenhouse gasses?

• NASA relies solely on weather balloons for data collection.
• NASA uses satellites and ground-based measurements to monitor greenhouse gases.
• NASA uses only computer models to predict gas levels.
• NASA monitors greenhouse gases through public surveys.
