At the treatment plant, the poop produces methane (甲烷) — a greenhouse gas that can make the earth warmer. However, methane can also be used as fuel (燃料). So, WSSC Water sells that gas to Montgomery County. And the county then uses it to power their buses! Marc Elrich is a go...
Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earth’s atmosphere and contribute to global warming. In its experiments, Keppler’s team used sealed chambers (室,房间;腔) that contained the same concentration of oxygen that Earth’s ...
Methane is also a powerful greenhouse gas. Which of the following activities can release a large amount of methane? A. Planting trees B. Burning coal C. Livestock farming D. Using solar E. nergy 相关知识点: 试题来源: 解析 C。解析:本题主要涉及不同活动与甲烷排放的关系。种树(Planting trees...
Due to the chemical bonds within its molecule methane is much more efficient at absorbing heat than carbon dioxide (as much as 86 times more), making it a very potent greenhouse gas. Fortunately, methane can only last about 10 to 12 years in the atmosphere before it gets oxidized and turns...
Greenhouse gases The world needs a deal duringCOP28to limit a nasty source of emission 温室气体 各国需在COP28大会期间达成协议以规范令人厌恶的排放源 METHANE IS A potent greenhouse gas. Over 20 years it has over 80 times the planet-cooking power of carbon dioxide, and is the culprit behind ...
Methane is an atmospheric trace gas, which influences numerous chemical processes and species in the troposphere and stratosphere. It makes a significant adverse contribution to the 'greenhouse' phenomenon. Its global concentration in the atmosphere has been rising since the start of the Industrial ...
可知,此处应填形容词,power的形容词为powerful,意为“有力的”,修饰名词greenhouse gas,符合题意。故答案为powerful。2.【答案】a【解析】根据题干要求,此处需填不定冠词,结合句意“菲律宾的地球母亲基金会是全球焚烧炉替代品联盟的成员,该联盟被称为盖亚。”可知,此处应填不定冠词,表示泛指,member的发音是以...
7、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global...
Methane (CH4) is an important greenhouse gas that also affects the chemistry and oxidation capacity of the atmosphere (Cicerone and Oremland 1988). The current burden of methane in the atmosphere is about 4700Tg (1 Tg =1 million tons) (Wahlen et al. 1989), and the global annual emission ...
Methane is present at about only 1.8 parts per million in the atmosphere, but is a key player there — it is a greenhouse gas, it is central to atmospheric oxidation chemistry, and it is ultimately a source of stratospheric water vapour, which influences ozone depletion. Moreover, the ...
