The search for life outside our solar system can, at times, sound a bit like a broken record. We are looking for planets not too much bigger or smaller than ours, circling stars not too different from our sun, orbiting at a distance not too far out or close in.Sappenfield, Mark...
How do greenhouse gases affect Earth's environment? What affects climate change? How does climate change? How does the water cycle affect climate change? How is global warming affecting coastal deserts? How do tornadoes affect the cryosphere?
Energy from the Sun reaches the Earth as heat. Some of this heat energy is subsequently/then radiated into space, while some of it is trapped by greenhouse gases in the atmosphere and reflected back to Earth. This is a natural process, but in recent decades, human activities have led to ...
Biodegradable plastic – made from plants rather than petrochemicals or fossil fuels – isn’t the simple answer either. Bacteria degrades bioplastic much more rapidly than conventional plastic, but that releases both methane and car...
How do hydrocarbons contribute to the formation of ozone in the atmosphere? Why does carbon dioxide have a significant influence on climate? Why is a certain level of greenhouse gases beneficial, but too high a level dangerous to life on earth?
Carbon dioxide (a molecule made up from one carbon and two oxygen atoms—CO2 in chemists’ notation) is a greenhouse gas, which means it contributes to the so-called greenhouse effect. Carbon dioxide and other greenhouse gases in the air trap some of the heat Earth would lose into space, ...
A. By releasing greenhouse gases. B. By absorbing carbon dioxide. C. By reducing the use of fossil fuels. D. By increasing renewable E. nergy sources. 相关知识点: 试题来源: 解析 A。解析:文中提到“Deforestation also contributes to global warming as trees absorb carbon dioxide.”,树木减少会...
How can we help to reduce greenhouse gases when using computers?在使用电脑时,我们如何帮助减少温室气体排放? 相关知识点: 试题来源: 解析 答案:Shut down the computer when we are through with it; put it on stand-by when we leave it for a while.反馈 收藏 ...
Let’s start there: The greenhouse effect is the natural process of how the sun warms the Earth’s surface. When greenhouse gases release into the atmosphere — these include carbon dioxide, methane, nitrous oxide, ozone, and water vapor — and trap the sun’s heat, they warm the average...
