Greenhouse gases (also known as GHGs) are gases in the earth’s atmosphere that trap heat. During the day, the sun shines through the atmosphere, warming the earth’s surface. At night the earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the...
Greenhouse gases are gases in Earth's atmosphere that trap heat, and without them, the Earth would be too cold to support life. But what if there are too many greenhouse gases? This lesson will explore these gases and the greenhouse effect. ...
What are the highest clouds in the atmosphere? Which layer in the atmosphere contains the most water vapor and gases? Which is the lowest layer of the atmosphere? What is the atmospheric pressure on earth? What is the highest layer of the atmosphere?

What are greenhouse gas emissions? The release of certain gases into the Earth’s atmosphere can create a “greenhouse effect”, in which heat becomes trapped and global temperatures rise. While emissions can result from natural causes, they are primarily the result of human activities, especially...
: such a gaz is “just” a gas mixed in the atmosphere that absorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases because neither nitrogen nor oxygen, the two most abundant gases of the atmosphere (78% and 21%, respectively), that many of...
In addition to carbon dioxide there are a number of gases (e.g., N/sub 2/O, CH/sub 4/, CF/sub 2/Cl/sub 2/, CFCL/sub 3/, etc.) which could affect the radiation balance of the earth's atmosphere. Recent measurements indicate that the atmospheric concentrations of these gases are...
Professor: Now, over the next few weeks, we're gonna focus on carbon and its role in what's known as the "greenhouse effect". Everyone knows what that is, right? But let's make sure anyway. Yes, Karlie? Student: The greenhouse effect is when gases in Earth's atmosphere act like th...
Other geologic changes occur when the [#highlight11]gases in the atmosphere or water react with rocks at the surface to form new chemical compounds[/highlight11] with different properties. An important example of this process was the removal of most of Earth’s carbon dioxide from its ...
