Trees absorb carbon from the atmosphere,in the form of carbon dioxide.A living tree is thus (1) an important storage site for carbon (2) that/which might otherwise be added to the levels of carbon dioxide in the atmosphere.And a big,living tree matters even (3) more(much)to the atmosp...
根据第一段“The villain in the atmosphere is carbon dioxide.(大气中的反派是二氧化碳)”可知,大气中的反派是二氧化碳。故答案为Carbon dioxide is the “villain” in the atmosphere. (2)题详解: 考查细节理解。根据第五段的“The sea level is rising very slowly from year to year. In all likelihood...
This gas, however, also plays a key role in life on Earth. Carbon helps form the protein and DNA found in living things. In the atmosphere, it combines with two oxygen atoms (原子) to form carbon dioxide. Carbon dioxide is necessary for photosynthesis (光合作用) . In the process, ...
to the first question is that carbon dioxide is still found in abundance on Earth, but now, instead of being in the form of atmospheric carbon dioxide, it is either dissolved in the oceans or chemically bound into carbonate rocks, such as the limestone and marble that formed in the oceans...
released into the atmosphere. But the tax is levied during theupstreamprocess, or when the fuel or gas is extracted from the Earth. Producers can then pass on the tax to the market by as much as they can. This, in turn, gives consumers a chance to reduce their own carbon footprints.2...
Carbon helps form the protein and DNA found in living things.In the atmosphere,it combines with two oxygen molecules(分子)to form carbon dioxide.Carbon dioxide is a crucial ingredient in photosynthesis(光合作用),the proc...
Unlike carbon monoxide, gaseous hydrocarbons at concentrations normally found in the atmosphere are not toxic 和一氧化碳不一样的是,在空气中常被发现的气体状的浓缩碳氢化合物是无毒的 "Sometimes, all that is required is to free up the rings in the ring grooves by cleaning out carbon." ...
The IPCC suggests that to prevent global temperature increases beyond 2 °C, NCS must remove and store around 10 GtCO2 from the atmosphere annually, of which ~62% is associated with forests1,2,3. In this context, forest restoration has gained massive global expansion with the promotion ...
Carbon dioxide gases with heat absorption and insulation functionality. It results are increasing in the atmosphere to form an invisible glass cover, solar radiation to the Earth's heat to the outer space cannot be spread, the result is that the surface of the Earth to heat up. Thus, carbon...
