The diagram below shows a model of the greenhouse effect... Which would happen MORE if there were NO GREENHOUSE GASSES in the atmosphere at all? * Process A (Infrared heat escaping into space)
Process B (Sun sending light energy to Earth)
Process C (Infrared heat being trapped in the atmosphere)
None of those processes would change if there were no greenhouse gasses.

Process A.

this is because the diagram shows that the infrared light returns into space. all of the other options are affected by the greenhouse gas layer, as the infrared rays bounce back onto earth. the greenhouse gases are very harmful to the earth because they cause all of those infrared heat rays to earth and they get trapped in the atmosphere because the greenhouse gases block them from escaping.
