Yes, greenhouse gases trap heat in the troposphere, which is the lowest layer of the earth's atmosphere.
Greenhouse Effect
the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up
Various gases have variable concentration. It depends from place to place.
greenhouse effect
No, greenhouse gases warm the air near the earth's surface by trapping heat from the warm earth that would otherwise escape into space.

They are called greenhouse gases.
"Greenhouse" gasses.
The greenhouse gases are in the troposphere, that's the lowest layer of the atmosphere. The sun's rays come in and warm the earth. The warm earth then radiates infrared heat, some of which is trapped by greenhouse gases in the lower atmosphere. These greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide and CFCs) warm up. They in turn radiate their warmth and some of it goes down again and warms the earth's surface. The heat can continue going up and down like that.
Greenhouse Effect
Ozone at earth's surface acts as polluntant. It is also a greenhouse gas.
greenhouse effect
We call it the greenhouse effect, which is natural, or the enhanced (or accelerated) greenhouse effect which is causing global warming.
