The greenhouse effect traps heat next to the Earth by allowing sunlight to penetrate the atmosphere and warm the surface. The Earth then emits this heat as infrared radiation, but greenhouse gases in the atmosphere, such as carbon dioxide and methane, absorb and re-radiate some of this heat back toward the surface, causing temperatures to rise.

How does the greenhouse effect warm the Earth?
The earth is surrounded by an atmosphere of air, made up of a number of gases. These gases form a 'blanket' which prevents all the sun's heat (infrared radiation) from reflecting back into space. If this greenhouse blanket was not there the surface of the earth would be about minus 18 degrees C (0ºF), instead of its present average temperature of 15 degrees C (59ºF). So this natural greenhouse effect is very useful.The gases that keep the earth warm are called greenhouse gases. The most important gas, causing about 75% of the natural greenhouse effect, is water vapor. The next most important is carbon dioxide.About 200 years ago humans started pumping carbon dioxide into the atmosphere, when the first factories began. Today the concentration of carbon dioxide is 40 per cent greater that it was in the 18th century. We have increased other greenhouse gases too, like methane, nitrous oxide and ozone.This is made worse by deforestation because plants take in CO2 and without them, less carbon dioxide is taken in, which in turn traps more heat.These increased amounts of greenhouse gases trap more infrared radiation and the earth's lower atmosphere is warming up. This is known as the enhanced greenhouse effect and is causing global warming, which, in turn, is causing climate change.A:it traps the heat in.Green House Gases are found in the troposphere. The sun's rays pass through this layer and reflect off of Earth's surface. Then after that the reflected light hits the gases causing them to heat. This heat is then re-reflected towards earth where it increases the warming.Carbon dioxide traps energy from the sun.The sunlight travels through the atmosphere until it hits the earth. Upon hitting the earth the energy changes from light to heat. Heat will move to an area where there is less heat. Normally toward space. Gases like water vapor, Carbon dioxide, and methane slow down this movement and cause the heat to collect closer to the earth. This in turn heats the planet.Cutting down the rain forests increases the greenhouse effect because it reduces the amount of clouds in the atmosphere. This allows more light to reach the earth and change into heat.Cutting down northern forests decreases the greenhouse effect by allowing the snow to accumulate. This keeps the light from turning into heat by reflecting more of it into space.
What does the greenhouse effect actually do?
The simple answer is that the greenhouse effect is a process that occurs in the atmosphere that reflects some of the heat radiated from the Earth's surface. This is similar to how a greenhouse 'traps' warmth, thus the name.This happens due to the ability of some gas molecules to absorb and radiate heat energy. Such molecules are carbon dioxide, methane, sulphur dioxide, and water. A lot of these molecules occur naturally in the Earth's atmosphere. And therefore, the greenhouse effect is partially a natural process. However, mankind also produces these types of molecules due to their own activity, increasing the amount of heat trapped.This has led to the 'greenhouse effect' or, worse still, the term 'global warming' to mean only mankind's involvement in this process. People tend to think that global warming will mean that the earth will get a few degrees warmer. What in fact is happening is that more energy is being put into the Earth's weather systems, with really unpredictable results. It might be that what we're doing is driving the planet to the next ice-age.If you want to get an idea of 'the absolute worst possible case scenario', read up upon the atmospheric conditions of the planet Venus. Venus has an amazingly high green-house effect, and temperatures on the planet's surface are hot enough to melt lead.At present we have an enhanced (or runaway) greenhouse effect. This is caused by all the extra carbon dioxide that man has put into the atmosphere since the Industrial Revolution, when we began burning coal, first for industry, then transport and the generation of electricity. The carbon dioxide from fossil fuel has been underground for millions of years, so it has not been part of the normal carbon cycle which keeps the planet warm. This enhanced greenhouse effect is causing the warming of the planet, with the ten hottest years on record all occurring since 1995.
What is the energy that heats earth's atmosphere?
1. Most of the short wave energy produced by the sun passes easily through the atmosphere and heats the surface of the earth. 2. The earth's surface then returns long- wave energy into the atmosphere. but this energy cannot easily pass out through the gases of the atmosphere. So some heat is retained in the atmosphere. 3. this is sometimes called the greenhouse effect because the glass of a greenhouse, like the atmosphere allows solar energy to pass through it and traps some of the energy inside.
How does conduction increase the temperature of above earth's surface?
[hope that you mean the "air layer" just above the earth] Conduction is the way of energy transmission in solids. But when it comes to the air it is by convection & radiation. So when the solar radiations reach the earth they heat up the surrounding air molecules. Further they heat up the ground. So next the ground becomes the heat source for the air & heat energy is transmitted to the air layer just above by convection.
How do greenhouse gases affect the heat flow into and out the earths atmosphere?
The more greenhouse gases there are the less heat flows out of the Earth's atmosphere. The less greenhouse gases there are the more heat flows out of the Earth's atmosphere. Greenhouse gases rarely flow into the earth's atmosphere
Which insulation holds the heat the best?
Glass traps solar heat. Greenhouses are made of glass so they absorb heat for the plants.

What describes the greenhouse effect?
Gases in the atmosphere trap the sun’s warmth -apex
What would happen if a person who is wearing a heavy winter jacket to place a thermometer inside a jacket next to his or her skin?
The thermometer would raise in temperature because the winter coat traps body heat.
Which planet is the hottest planet and why?
Venus is the hottest planet. It is second closest planet to the sun (next to Mercury) but it is the hottest because clouds surround it trapping heat in like a blanket, creating a green house effect.
Why is plastic foam good at reducing heat loss through walls?
I think it´s becaus the foam is in, principle, a solid with a great quantity of minuscule boubles of air. The heat reducing effect happens thanks to the iar inside the boubles. The material that forms the boubles absorbs a certain amount of heat, and when you apply heat to the exterior, it has to heat the material first then the heat transfer from the material to the air in the bouble. So that effect stacks up subsequently with the next layer of boubles, and the next and so on. Hope I helped you! :-)

How does the extinction of the half horse half zebra effect the environment?
It effect the enviorment because now days, the next generation will not be able to know about this kind of creature living on earth!
Is geothermal energy a renewable resource or a non renewable resource?
Renewable. Like the heat of the sun, the heat of the Earth's core isn't going anywhere in the next couple of billion years.
