Question

15 multiple choice 2 points most water vapor enters earths atmosphere by the processes of condensation and precipitation radiation and cementation conduction and convection evaporation and transpiration

Explanation:

Evaporation is the process where water changes from liquid to gas (vapor) from water bodies like oceans, lakes, etc. Transpiration is when plants release water vapor through their leaves. These two processes are major sources of water vapor in the atmosphere. Condensation is water vapor turning back to liquid, precipitation is water falling from the atmosphere (rain, snow etc.), so the first option is wrong. Radiation is energy transfer, cementation is a geological process (not related here), so the second option is wrong. Conduction and convection are heat transfer mechanisms (not for water vapor entry), so the third option is wrong.

Answer:

evaporation and transpiration (the fourth option)
