It's a device (structure) that allows heat to get in freely, but holds it in so that the heat builds up.

Classically it is a building with walls and roof made of glass: the sunlight gets in but it's hard for the heat to get out.

What will be the conclusion in greenhouse effect?

The Greenhouse Effect is real. There is no question that the presence of CO2 and other greenhouse gases keeps this planet comfortably warm. The alarming crisis of Global Warming arises from the ever-increasing concentrations of greenhouse gases in our atmosphere as a direct result of human activity. All of the science suggests that increasing greenhouse gas concentrations will inevitably lead to a rise in global temperature. How much and how quickly temperature will rise is disputed. Nonetheless, as scientists and citizens, we have a responsibility to act now, to educate and work towards changing our habits and our impact on the planet. thanks................

How does a greenhouse works?

This answer is for the "greenhouse effect" - It works by the co2 build up and slowly destroying the ozone layers causing a increase in temperature. So the more factories and cars produce co2 the more hotter it will get. A real greenhouse is just a building with transparent walls and roof that allows sunlight in but blocks much of the normal heat loss.

How do greenhouse gases work to trap heat in the Earth's atmosphere?

Greenhouse gases, like carbon dioxide and methane, trap heat in the Earth's atmosphere by allowing sunlight to enter and warm the planet's surface. When the surface absorbs the sunlight, it emits infrared radiation, which is then trapped by the greenhouse gases. This trapped heat leads to an increase in temperature, known as the greenhouse effect.


How does saran wrap work with plants?

What are greenhouse gas offsets and how do they work?

A carbon offset is a financial tool aimed at a decrease in greenhouse gas emissions. Carbon offsets are measured in metric tons of carbon dioxide-equivalent which can exemplify 6 primary families of greenhouse gas emissions. One carbon offset constitutes the step-down of one tonne of carbonic acid gas or its equal in other greenhouse gases. this text was taken from: www.sofame.com/Carbon-Offsets
