10 Questions
Why does an increase in carbon dioxide and methane in the atmosphere lead to a higher temperature on Earth?
They absorb outgoing infrared energy emitted by Earth's surface and redirect it back towards the surface.
Why are greenhouse gases crucial for sustaining life on Earth?
They absorb and redirect energy, balancing the energy flow in and out of the Earth system.
How does methane differ from carbon dioxide in its efficiency as a greenhouse gas?
Methane is more effective at absorbing and redirecting energy than carbon dioxide.
What is the primary effect of sulfur dioxide in the atmosphere?
Forming sulfuric acid that reflects incoming visible light
How does ozone primarily affect energy in the stratosphere?
By absorbing ultraviolet light energy
What is the short-term effect of adding sulfur dioxide to the atmosphere?
Causing cooling by reflecting incoming visible light
What is a major source of carbon dioxide released into the atmosphere by human activity?
Combustion of fossil fuels
Which human activity contributes significantly to methane emissions in the atmosphere?
Landfills
Why is methane released by the keeping of livestock considered a significant contributor to greenhouse gases?
Because of the animals' digestion process
How does deforestation contribute to the increase of carbon dioxide in the atmosphere?
By releasing stored carbon when trees are cut down
Learn how carbon dioxide and methane affect Earth's energy balance, causing temperature increases when their levels rise in the atmosphere. Understand why these gases redirect outgoing energy, leading to an imbalance between energy entering and exiting the Earth system.
