Question

Over the past century, the concentration of greenhouse gases in the atmosphere has_____ This has led to _____heat being held in the troposphere, where infrared radiation is _____ likely to encounter a greenhouse gas molecule and be_____

the first dash waved up and down, increased, decreased and been unchanged

the second dash More, less the same amount of

the last dash transmaitted, absorbed and re-emmitied, reflected down

I think increased, more, more and transmaitted I really need help thank you.

Answer 1

increased
more
more
absorbed and then re-emitted back toward earth

The high frequency (energy) photons from the sun tend to scoot through the atmosphere and warm up the earth surface. That causes the earth surface to emit lower frequency infrared (hot) photons upward. CO2 or CH4 molecules in the air absorb those infrared rays and get hot, radiating them in all directions, including back to the ground heating it up more.
