Which best describes how greenhouse gases heat the Earth?
A planet’s surface absorbs visible sunlight and returns this absorbed energy to space as infrared light. Greenhouse gases slow the escape of this infrared radiation, which thereby heats the lower atmosphere.
Which best explains the Earth’s greenhouse effect?
Which statement best describes the greenhouse effect? It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Why do greenhouse gases heat the Earth?
The Short Answer: The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere.
How do greenhouse gases trap heat on Earth?
Greenhouse gases keep the Earth warm by preventing heat from escaping, they do nothing to actually warm the Earth. The greenhouse effect is when sunlight enters the atmosphere, hits the Earth and is changed to heat and then that heat is radiated is back to space.
How does a greenhouse affect the earth’s temperature?
A real greenhouse traps heat because its glass stops the warm air inside from transferring heat to the colder surrounding air. Greenhouse gases don’t stop heat transfer in this way, but as this piece explains, in the end they have a similar effect on the Earth’s temperature.
What causes the Earth to trap more heat?
NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This causes Earth to warm up.
How is the Earth’s atmosphere the same as a greenhouse?
Earth’s atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth’s surface warms up in the sunlight.
What are the gases that trap heat in the atmosphere?
These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth’s surface warms up in the sunlight. At night, Earth’s surface cools, releasing heat back into the air.
