What Are Greenhouse Gases ? What Are the Sources of What is the Prospect for FutureAre, WhyLevels, Atmospheric
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...
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...

The two main gases responsible for thegreenhouse effect(and not noly itsrecent increase) are : Water vapour (H2O), carbon dioxyde (CO2). There are others such gases, and even many others. Some of them are “natural”, which means that they were present in the atmosphere before the apparit...
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，甲烷和一氧化二氮） ，而另一些完全是人为的（某些工业气体）。随着时间的推移，如果大气中...
A. Decrease in greenhouse gases. B. Increase in greenhouse gases and deforestation. C. Only deforestation. D. Only increase in greenhouse gases. 相关知识点: 试题来源: 解析 B。原因:文章中提到“One of the main causes of global warming is the increase in greenhouse gases...Another cause of ...
In addition to CO2, methane and nitrous oxide are two of the most important greenhouse gases, the annual emissions of which are greatly increased by human activities. Methane emissions are particularly dominant in the area of livestock farming. With regard to natural emission sources, methane is ...
解析 D。解析:如果温室气体的量持续增加,全球气温将会上升(The global temperature will rise)。温室气体增加会使地球变暖而不是变冷(The Earth will get cooler);气候会发生变化而不是保持不变(The climate will remain the same);温室气体增加与海水盐度变化(The sea will become less salty)没有直接关系。
