Atmosphere of Venus water and subsequent rise of the levels of other greenhouse gases. Despite the harsh conditions on the surface, the atmospheric pressure and temperature at about 50 km to 65 km above the surface of the planet is nearly the same as that of the Earth, making its upper atmosphere the most Earth-like area in the Solar System, even more so than the surface of Mars. Due to the similarity in pressure and temperature and the fact that breathable air (21% oxygen, 78% nitrogen) is a lifting gas on Venus in the same way that helium is a lifting gas on
Most common words in English about half of all written English. According to a study cited by Robert McCrum in "The Story of English," all of the first hundred of the most common words in English are of Anglo-Saxon origin, except for "people", ultimately from Latin "populus", and "because", in part from Latin "causa".
