Venus is sometimes thought of as earth's sister planet. in some ways the two planets are very similar. venus is only slightly smaller than earth, has a similar density and chemical composition. yet venus does not support life like earth. what is one important reason why venus cannot support life as we know it? a) venus has no atmosphere. b) venus' surface temperature is about 480oc. eliminate c) the water on venus' surface is too hot to support life. d) venus' dense clouds keep the planet's temperature very low.

B) Venus' surface temperature is about 480oC.

Explanation:

Venus is almost the size of Earth and the ingredients present in the two bodies are similar, but the similarities stop there. The second planet closest to the Sun is covered by heavy clouds of sulfuric acid and its surface temperature, above 460 ° C, can melt lead and make life impossible for any organism. A recent study, however, shows that things have not always been there. At the time when primitive bacteria began to populate the Earth, Venus was possibly a much more life-friendly planet, endowed with a mild climate and oceans with a depth of up to 2,000 meters. It would thus be the first stronghold of the Solar System to be habitable.

i really wish i could answer this question for you

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
