Without the Greenhouse Effect the Earth would be...
too warm for life
too cold for life
The Greenhouse Effect: Put these statements in the correct order:
1) so it emits infrared back towards space.
2) This then heats up the greenhouse gases in the atmosphere
3) Infrared radiation from the Sun heats the surface of the Earth.
4) which reradiates the infrared back towards the Earth.
5) This warms the surface of the Earth

1, 2, 3, 4, 5
3, 5, 1, 2, 4
2.1., 4, 3, 5
Why does the Earth heat up?
This happens when the amount of radiation emitted by the Earth is greater than the amount it absorbed.
This happens when the amount of radiation absorbed by the Earth is greater than the amount it emits.
This happens because the Sun gets bigger and emits more infrared radiation.
Which statement is true?
Climate change leads to the increase in greenhouse gases which leads to global warming.
Global warming leads to the increase in greenhouse gases which leads to climate change.
The increase in greenhouse gases leads to global warming which leads to climate change.
