Greenhouse gas:

Greenhouse gas (GHG) are gases that trap heat in earth's atmosphere. They are named after greenhouse, a place with windows that allows sunlight to enter. This sunlight creates warmth and the greenhouse doesn't let the warmth escape. That's also the way greenhouse gases act.

They allow the sunlight to pass through the atmosphere and don't let that heat escape thus keeping the earth from getting too cold. Some of these gases are water vapours, carbon-di-oxide, ozone and methane. Greenhouse gases help in keeping the earth heat but due to human activities there has been an increase these gases in the atmosphere leading to global warming.
