近日,在火星上“旅行”的“好奇号”火星车又有了新发现。它在考察火星上盖尔环形山内的夏普山时发现,这座山其实是由一个巨大的湖泊在数千万年里沉积物质而形成的。这个发现表明,远古的火星上曾经存在能够长时间产生湖泊的气候环境。夏普山高达5千米,低处的山腰上暴露出了成百上千层岩层。这些岩层,有些形成于湖泊沉积,有些形成于河流沉积,还有些形成于风成沉积,它们见证了一个反复被湖水灌满又蒸发殆尽的湖泊历史。这个湖泊遗址远比以前探查过的其他火星远古湖泊要大得多,湖水持续存在的时 Recently, a new discovery has been made on the Mars Curiosity rover on Mars. When examining Mount Sharp in Mars, the Upper Gall craters, it discovered that the mountain was actually formed by the deposition of matter on a huge lake for tens of millions of years. This discovery shows that there was a climate on ancient Mars that allowed lakes to develop for a long time. Sharp Hill up to 5 km, low mountainside exposed hundreds of layers of rock. Some of these formations are found in lakes, some in river sediments and some in eolian deposits. They witness a history of lakes that have been repeatedly flooded with lakes and evaporated. The lake is far more ancient than other previously ancient Mars lakes explored and the lake persists
