Question

question 39 (2 points) green house gases 1) make the earth habitable by trapping heat and warming the atmosphere 2) are all man - made 3) include carbon dioxide, methane, and radon 4) radiate heat from the earths surface back into the space

Explanation:

Green - house gases trap heat in the Earth's atmosphere, making the planet habitable. Some greenhouse gases are natural (e.g., water vapor), so option 2 is incorrect. Radon is not a greenhouse gas, so option 3 is wrong. Green - house gases absorb and re - emit heat back towards the Earth's surface, not radiate it into space, so option 4 is incorrect.

Answer:

1. Make the earth habitable by trapping heat and warming the atmosphere
