The Chicxulub crater . The bright material on the rim of the crater is ice. Such gyres are thought to contain up to 100 million tons of debris. The crater 's diameter is 96 miles(154 kilometers).
That's because erosion on Earth causes some craters to disappear. The diameter of the crater is 96 miles(154 kilometers). Billions of years ago, there were streams and lakes within the crater . 该陨石坑 自1971年以来一直在燃烧,至今已近50年。 The crater has been burning since 1971; almost 47 years. But diamonds were only in those that were found on the rim of Meteor Crater . Impact cratering is the most notable geological process on the Moon.Instead, the deciding factor may have been the crater 's shape. 该陨石坑 自1971年以来一直在燃烧,至今已近50年。 The crater has been burning since 1971, close to 50 years. 月机会号火星车在前往维多利亚陨石坑 的路上用了整整一个月的时间。 Opportunity spent the month of July on the road to Victoria crater . Permanent shade craters are also thought to hold 100 million tonnes of water. The crater also is thought to be relatively young, and the regolith is freshly exposed. In 1902, a white cloud was observed briefly in the vicinity of the crater . 当荷兰地质学家在1914年发现陨石坑 时,颜色为红色,蓝色和白色。 When Dutch geologists discovered the craters in 1914, the colors were reported to be red, blue and white. 这些陨石坑 讲述了地球和月球形成后太阳系所发生的故事。 Those craters tell the story of what happened in the solar system after the Earth and the moon were formed. 埃特纳火山的游客可以沿着陨石坑 和裂缝走,往往越来越近,看到熔岩或蒸汽。 Visitors to Mount Etna can walk along the craters and fissures, often getting close enough to see the lava or steam. 由于陨石坑很年轻并且气候很干燥,该陨石坑 是地球上保存最好的陨石坑。 Because of the crater's young age and the dry climate Meteor Crater is the best preserved impact crater on Earth. 据估计,这个陨石坑 有2.023亿年(400万年),其影响是在古生代。 The crater is estimated to be 2.023 billion years old(± 4 million years), with impact being in the Paleoproterozoic Era. 陨石坑 是最容易看到在这个边界,因为太阳是在一个较低的角度,并投下很长的阴影。The craters are most easily seen at this boundary since the sun is at a low angle and casts very long shadows there. 像月球上的其他轨道,陨石坑 和地质特征一样,这块岩石和它所雕刻的路径讲述了一个故事。 As with other tracks, craters and geological features on the Moon, this rock and the path it carved tells a story. 他们估计,陨石坑 覆盖了其表面的10%以上,使其成为小行星带中陨石坑最多的物体。 They estimate that craters cover more than 10 percent of its surface, making it the most heavily-cratered object in the asteroid belt. 我们所看到的一切,包括--陨石坑 --我见过陨石坑 的登月舱下面的特写镜头。 Everything we have seen, including- there are craters - I have seen close-ups under the LEM of the crater . 科学家们认为,该陨石坑 的很多沉积物都坚持在良好状态,其中一些沉积物可能存在了35亿年之久。 Scientists believe that the crater holds many sediments in great condition- some may be 3.5 billion years old. CaSSIS拍摄了一幅40公里长的陨石坑 北缘的图像,清晰地展示了其迷人的形状和结构,以及明亮的冰沉积物。 CaSSIS imaged a 40-kilometer-long chunk of the crater 's northern rim, neatly showcasing its intriguing shape and structure, and its bright icy deposits.
