Without the Greenhouse Effect the Earth would be...
too warm for life
too cold for life
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?
