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...
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...
What gases make up trace gases?The Earth's Atmosphere:The atmosphere of the Earth is unique in our solar system as it contains mostly nitrogen gas and is the only atmosphere that also contains significant quantities of molecular oxygen. Most of the other planets in our solar system have high...
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 is the use of greenhouse gases A.They allow energy from the sun to enter but prevent energy from leaving.B.They allow energy from the sun to leave but prevent energy from entering.C.They protect the plants.D.They protect the earth....
The heat caused by infrared radiationis absorbed by greenhouse gases such as carbon dioxide, which slow its escape from the atmosphere.Although greenhouse gases make up only about 1 percent of the Earth's atmosphere, they regulate ourclimate by trapping heat in a kind of warm-air blanket that...
许多地球大气层中的化合物都是“温室气体”。这些气体让阳光自由地进入大气层。当阳光照射到地球表面，一部分阳光作为红外辐射（热）被重新辐射回太空。 温室气体吸收红外辐射的热量，并且把这个热量保存在大气层中。许多气体都有这些“温室”属性。 其中一些是大自然产生的（水蒸汽，二氧化碳，甲烷和一氧化...
