Greenhouse gases do exist and are not just a theory. Scientists have known for hundreds of years that some atmospheric gases (water vapour, carbon dioxide, methane and others) absorb heat rising from the surface of the earth.
Part of the theory of global warming is that greenhouse gases capture the earth's heat. If more greenhouse gases are added to the atmosphere then more heat will be retained.We can measure that levels of greenhouse gases have increased, and we can measure that temperatures have risen. These measurements thus support the theory of global warming.
The greenhouse effect warms the gases in the atmosphere.
Because they have the same effect as a greenhouse. They trap heat inside them, just like a greenhouse does to help the plants grow.
two greenhouse gases are carbon dioxide and methane
the two major gases that cause greenhouse gases are methane and carbon dioxideco2, methene, evaporates

The greenhouse gases contribute to the greenhouse effect. Greenhouse gases are inescapable.
One theory is to increase the input of greenhouse gases so that the next "ice age" can be averted.
"Greenhouse gas" is just a catchy term that means "traps heat." Due to the way the atmosphere is layered, some gases trap more heat than others; CO being about the weakest "greenhouse gas."
Oxygen is not a greenhouse gas. It deceases the greenhouse gases.
Greenhouse gases must have three atoms, so gases like hydrogen (H2) and Oxygen (O2) are not greenhouse gases.
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do

Greenhouse gases are naturally occurring gases but by increasing the concentrations of greenhouse gases in the atmosphere we are contributing to global warming.
Yes. The greenhouse gases trap the sun's heat.
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.
