Visible light heats the earth and the earth emits infrared energy which is absorbed by green house gases that trap the heat.
Greenhouse gases trap infrared heat (from the sun) rising from the surface of the earth. More greenhouse gases trap more heat, and this is the situation now. Increasing levels of carbon dioxide (CO2) in particular are trapping more heat and causing a global warming.
They are called "greenhouse gases" because, like the glass of a greenhouse, they capture heat energy being re-radiated (as infrared rays) from the Earth.
Greenhouse gases absorb the infrared rays. These are heat rays of the sun.
Greenhouse gases capture heat in the greenhouse effect. If the amount of gas increases then it causes global warming.

In the atmosphere
Yes, clouds and water vapor are major greenhouse gases. They trap energy entering and infrared energy leaving earth, helping heat the earth and keep it at a temperature suitable for life.
Heat trapping gases absorb infrared radiation. Three of the major gases that trap heat are carbon dioxide, water vapor and methane.
Greenhouse gases absorb the infrared rays. These are heat rays of the sun.
Yes, some of it can. Infrared radiation is trapped by greenhouse gases, but not all of it is trapped. These gases only trap radiation in very specific parts of the electromagnetic spectrum, so there are "windows" where it can escape.
Greenhouse Gasses
Some atmospheric gases trap infrared heat radiated by the Earth. They are called greenhouse gases and the process is called the greenhouse effect. Among the gases are water vapor, carbon dioxide, and methane.
Greenhouse gases (GHG) are any gas or types of gases that trap, absorb and emit heat.
Carbon dioxide, methane, nitrous oxide and CFCs (chlorofluorocarbons) trap infrared radiation (heat) causing a greenhouse effect.
