“I wanted to write this paper for a very long time,” Chevrier said, “because I think there is a lot of confusion, a lot of misunderstanding, and a lot of erroneous interpretations of what the research papers are saying about the state of liquid water on Mars.” The authors suggest t...
One idea is that these slope lineae could be formed by the flow of liquid water. But there’s also other ideas where you actually don’t need liquid water to explain the formation of these dark streaks. Maybe they could form through sand flow or that kind of thing. So, is there water...
mountains,canyons (峡谷),and crates (火山坑).There are no rivers oroceans.It is a planet without any liquid (液态) water.It was named by the ancient Romans for their God of War.It is very cold on Mars.Mars is much colder than our planet.The temperature on Mars is 80degrees below ...
Mars' surface looks like a red desert. There are mountains, canyons (峡谷), volcanoes (火山) and so on. It is a dry planet without any liquid water (液态水). It does have ice caps at its north and south. Some of this ice is frozen (冻结的) carbon dioxide. Evidence shows that Mar...
Even more evidence points to "water bodies" lurking under Mars's surface. See the findings that have shook some planetary scientists to their core.
So there's reason to believe that we'll get an answer to that piece of the puzzle one day. 2.Why is geological evidence of liquid water on Earth and Mars three to four billion years ago problematic? A. It suggests that the solar system is younger than it could possibly be. B. It...

You may not use any of the words in the bank more than once.Last week, NASA confirmed evidence of liquid water on Mars. Fluid erosion and deposition ()patterns appear to be 1, increasing during warm seasons, decreasing in _2 seasons. It is a melt and flow pattern, evidence that Earth...
There, the gas blanket trapped heat and warmed the planet up until liquid water began to flow, forming Mars' rivers and lakes.(这个想法是这样的:当火星寒冷冻结时,火山继 续向大气中喷射二氧化碳和氢气等温室气体。 在那里, 气层捕获热量并使行星升温,直到液态水开始流动,形 成了火星的河流和湖泊)”...
There are signs of liquid water on Mars. For years Mars has been known to have water in the form of ice. The first signs of trickling water are dark stripes or stains on crater wall and cliffs seen in satellite images. Due to Mars atmosphere this water would have to be salty to ...
