If you want to see an example of the greenhouse effect, just go to Venus! (Atmosphere of Venus: 96.5% carbon dioxide. Temperature of Venus: 467°C (872°F))
To answer your question, when rays of the sun come through our atmosphere they heat the land, water and such. This heat then radiates out from the warmed earth. Some of the goes back through the atmosphere and out into space, but the greenhouse gases capture and retain some of this heat. This is the natural greenhouse effect that keeps the planet warm. Any extra greenhouse gases (from man's activities of burning fossil fuels and deforestation) are too much for the natural carbon cycle to remove, so they absorb extra reflected heat. This is what is causing global warming.
Answer:
The popular view is that the atmosphere has some sort of layer of carbon dioxide "up there" that reflects heat back down to Earth rather than letting it escape to space. That would be like the glass on a greenhouse trapping warm air in while letting the sunlight through to increase the heat. In a greenhouse the sunlight warms the benches and floor, he warm objects heat the air, the air is trapped by the double layer of insulating glass.
It does not happen that way in our atmosphere.
Sunlight comes in and warms the Earth's surface. It warms the gases in the air too, at least some of them with a bond size that gets excited by sunlight. These special gases are greenhouse gases (carbon dioxide, methane, water vapour and a few others). They are mixed evenly through all of the atmosphere (not in layer). When the gases are warm they share their heat with all their gas molecule neighbour and heat the atmosphere generally.
The effect i more like wet sand in a microwave. Microwaves do not heat sand. They do heat water. When you microwave wet sand, the water heats up - might even turn to steam. The hot water warms the sand.

Why would increased levels of greenhouse gases contribute to higher temperatures?
Increased levels of greenhouse gases trap more heat in the Earth's atmosphere, creating a "greenhouse effect." This leads to higher temperatures as more heat is retained and absorbed by the Earth's surface.
What is the name of the theory that states greenhouse gases are causing the earths surface temperature to get warmer?
The theory that states greenhouse gases are causing the Earth's surface temperature to rise is known as the greenhouse effect. This phenomenon occurs when gases such as carbon dioxide, methane, and water vapor trap heat in the atmosphere, preventing it from escaping into space. As a result, this leads to an increase in global temperatures, contributing to climate change.
Is the Earth getting Warmer and Why?
Well it all starts with Greenhouse gases i.e. Carbon dioxide, Methane, water vapour etc. When the sunshine's, the ocean and the plants absorbs it, then it releases it. But, that was before. Now the earth is also releasing greenhouse gases by deforestation and burning fossil fuels. Greenhouse gases trap extra energy from the sun. So if the ocean and plants absorb 100 joules and then lets out 100 joules, because of the greenhouse gases only about 75 joules will actually be let out of the earths atmosphere. The remaining 25 joules will be trapped in the earths atmosphere.
What atmospheric gases enhance the greenhouse effect?
Carbon dioxide, methane, water vapor, and nitrous oxide are greenhouse gases that enhance the greenhouse effect. These gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures and climate change.
What are the Benefits of Natural Greenhouse Gases?
one pro is that it helps regulate earths temperature, but with fossil fuals which emites greenhouse gases it makes earth get hotter. and that's how you get global warming.
How do greenhouse gases affect the earths atmosphere?
They slow the loss of heat
Trapping of heat in the earths atmosphere by certain gases is known as the?
greenhouse effect
What would happen to global temperatures if the amount of greenhouse gases increased or decreased?
If the amount of greenhouse gases increased, it would lead to a stronger greenhouse effect, trapping more heat in the Earth's atmosphere and causing global temperatures to rise. On the other hand, if the amount of greenhouse gases decreased, it would weaken the greenhouse effect, resulting in cooler global temperatures.
How would earths average temperature be different if there were no greenhouse gases in the atmosphere at all.?
If there were no greenhouse gases in the atmosphere, Earth's average temperature would be significantly colder. Greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, helping to keep the planet warm. Without them, Earth's surface would not retain as much heat from the sun, resulting in much lower temperatures.
Do greenhouse gases lead to freezing temperatures at the south pole?
No. Greenhouse gases trap the sun's heat, so they lead to warmer temperatures all around the world, including at the south pole.
Why would increased levels of greenhouse gases contribute to higher temperatures?
Increased levels of greenhouse gases trap more heat in the Earth's atmosphere, creating a "greenhouse effect." This leads to higher temperatures as more heat is retained and absorbed by the Earth's surface.
What is it called when heat energy gets trapped in earths atmosphere?
That phenomenon is known as the greenhouse effect, where gases in the Earth's atmosphere trap heat from the sun, leading to an increase in temperatures on the planet.
What is the name of the theory that states greenhouse gases are causing the earths surface temperature to get warmer?
The theory that states greenhouse gases are causing the Earth's surface temperature to rise is known as the greenhouse effect. This phenomenon occurs when gases such as carbon dioxide, methane, and water vapor trap heat in the atmosphere, preventing it from escaping into space. As a result, this leads to an increase in global temperatures, contributing to climate change.
What are gases such as carbon dioxide and methane called that help maintain the warm temperatures near the surface of Earth?
These gases are called greenhouse gases. They act like a blanket, trapping heat in the atmosphere and contributing to the Earth's greenhouse effect. They play a vital role in keeping Earth's temperatures suitable for life.
How do ocean currents originate and affect Earths climates?
How are atmospheric gases like the glass in a greenhouse
What happens when levels of greenhouse gases in Earths atmosphere increase?
When levels of greenhouse gases increase in Earth's atmosphere, they trap more heat from the sun, leading to global warming and climate change. This can cause rising temperatures, melting ice caps, more frequent and severe weather events, and disruptions to ecosystems and habitats. It is essential to reduce greenhouse gas emissions to mitigate these impacts.
