How does a greenhouse gas warm the Earth quizlet?
How does the greenhouse effect keep Earth warm? By trapping some of the infrared rays, the atmosphere around us remains warm and stable. This is necessary for sustaining life.
How does a greenhouse gas heat the atmosphere quizlet?
These gases are called greenhouse gases because they trap heat in the earths atmosphere. These gases allow sunlight to enter the earths atmosphere, and when the light is reflected back into space, the gases absorb the infrared radiation and trap the heat in the atmosphere.
How do greenhouse gases work quizlet?
How does the greenhouse effect work? Visible light is emitted through the sun and passes through the infrared-blocking greenhouse gases. The light then warms the surface of the earth and turns into infrared heat, which is then trapped in the atmosphere and reflected by greenhouse gases.
How is Earth’s lower atmosphere warmed?
Measurements from satellites and weather balloons show that the lowest layer of the atmosphere—where we live, airplanes fly, and weather occurs—is warming. Greenhouse gases are building up in this layer, trapping heat radiated from Earth’s surface and raising the planet’s temperature.
How do greenhouse gases heat up Earth’s troposphere quizlet?
What is the greenhouse effect? The sun’s rays enter earth’s atmosphere and are trapped by greenhouse gases and they heat up the earth. Melting ice causes the earth to warm even further.
How do greenhouse gases affect Earth’s climate quizlet?
How does the greenhouse effect influence the climate on earth? It traps heat from the sun and it prevents earth from getting too cold. including carbon dioxide, methane, and nitrous oxide, absorb some of the radiated heat, keeping the atmosphere and the surface of Earth warm.
What is the primary function of a greenhouse gas?
Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere.
What role do greenhouse gases play?
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth’s outgoing energy, thus retaining heat in the atmosphere.
How do greenhouse gases absorb heat?
Greenhouse gases (carbon dioxide, methane, water vapor, etc.) are transparent to visible light, but opaque to infrared radiation. That means the sunlight travels through them but the heat is blocked by them. That is how greenhouse gases trap heat.
How is the Earth’s atmosphere heated?
Conduction, radiation and convection all play a role in moving heat between Earth’s surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth’s surface. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.
