Answer:
The correct answer is - heat the atmosphere near the surface of the earth.
Step-by-step explanation:
There are several different types of greenhouse gases such as carbon dioxide, methane, CFC, and nitrous oxide. These gases absorbed energy comes from the sun.
The radiations that come from the vibrating molecules are absorbed by greenhouse gases such as carbon dioxide and methane that increase the temperature of the atmosphere near the earth's surface and heat near the Earth's surface. Without this effect, the atmosphere would be at freezing temperature or below, so it is a somewhat natural process.
