Question

what does the heat absorbed by gases create?
global warming
greenhouse effect
photosynthesis
blue skies

Explanation:

Greenhouse gases absorb heat radiated from Earth's surface and re-emit it, trapping heat in the atmosphere. This process is defined as the greenhouse effect. Global warming is a result of an enhanced greenhouse effect, photosynthesis is a plant process using light, and blue skies come from light scattering (Rayleigh scattering).

Answer:

greenhouse effect
