Why does an increase in carbon dioxide and methane in the atmosphere lead to a higher temperature on Earth?
Why does an increase in carbon dioxide and methane in the atmosphere lead to a higher temperature on Earth?
- They enhance the ozone layer, leading to a greenhouse effect.
- They block incoming solar radiation, causing a build-up of heat on Earth's surface.
- They absorb energy from the Sun and trap it inside the atmosphere.
- They absorb outgoing infrared energy emitted by Earth's surface and redirect it back towards the surface. (correct)
Why are greenhouse gases crucial for sustaining life on Earth?
Why are greenhouse gases crucial for sustaining life on Earth?
- They prevent harmful UV radiation from reaching the Earth's surface.
- They absorb and redirect energy, balancing the energy flow in and out of the Earth system. (correct)
- They trap heat in the atmosphere, maintaining stable global temperatures.
- They regulate the planet's temperature, preventing extreme heat or cold.
How does methane differ from carbon dioxide in its efficiency as a greenhouse gas?
How does methane differ from carbon dioxide in its efficiency as a greenhouse gas?
- Methane persists in the atmosphere for a longer period than carbon dioxide.
- Methane absorbs more solar radiation than carbon dioxide.
- Methane is more effective at absorbing and redirecting energy than carbon dioxide. (correct)
- Methane is less efficient at trapping heat in the atmosphere compared to carbon dioxide.
