What is true of greenhouse gases

Let us explain about green house gases

Explanation:

Green house effect

It can be explained as:

The sun emit radiations that consist of infra red rays, ultra violet rays and visible light. The infra red rays (responsible for heating) when come from sun, it travels through atmosphere and reaches earth surface. On striking the earth surface, it gets reflected and reflected infra red ray has greater wavelength. Then this reflected rays moves back through atmosphere. On doing so, they encounter certain gas molecules like carbon dioxide, methane etc. This gases absorb these rays and do not let them to escape through them. As a result, they get trapped. As we have already mention that they cause heating effect, due to this property they raise the temperature of atmosphere leading global warming.
