What are Greenhouse Gases ?Gillenwater, Michael
Since the Industrial Revolution, humans have been releasing larger quantities of greenhouse gases into the atmosphere. In the past century that amount has increased dramatically, with the knock-on effect of global warming. Global temperatures have accelerated in the past 30 years and are now the hi...
Now, the Earth’s atmosphere does the same as greenhouse do. During the day when the sun shines, it heats up the Earth’s atmosphere. The Earth absorbs some of this energy and heats up. At night, when temperature goes down, the Earth cools down by giving different form of energy called...
Greenhouse gases are naturally occurring gases, such as CO2, methane, and sulfur dioxide, that trap heat on Earth. Without greenhouse gases, what would be the average temperature on earth? How do you measure up? Only 43% of readers got this right. Greenhouse gases, in moderation, are needed...
The atmosphere is the layer of gases that surround the earth, and it provides the air that we need to stay alive. Although the majority of the atmosphere is made of nitrogen and oxygen, there are other gases found in trace amounts that are known as greenhouse gases....
"natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and ...
1. Definition of Greenhouse Gases (GHGs): Greenhouse gases are gases in the Earth's atmosphere that have the ability to absorb and re-radiate infrared radiation. This process contributes to the greenhouse effect, which leads to global warming. 2. Mechanism of Action: The key characteristic of ...
A. Gases that cool the planet B. Gases that are only produced by nature C. Gases that trap heat in the atmosphere D. Gases that are harmless to the E. nvironment 相关知识点: 试题来源: 解析 C。“greenhouse gases”指的是温室气体,能在大气中捕获热量。选项 A 温室气体是使地球升温而非降...
If the amount of greenhouse gases continues to increase, what will probably happen? A. The Earth will get cooler. B. The climate will remain the same. C. The sea will become less salty. D. The global temperature will rise. 相关知识点: ...
The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
