600,000 years 前 in mars the atmosphere was much もっと見る dense, there was much もっと見る carbon dioxide in the atmosphere, because of this the dust had an easier time lifting off; causing deadly dust storms much like what took place in the American dust bowl in the 1930s, but much worse. The atmosphere has since frozen. “Mars lacks a molten core that provides a magnetosphere that in the past protected it's atmosphere.” Eric 発言しました in one of the replies. “Without a magnetosphere, Mars cannot protect and/or maintain a significant atmosphere. From everything I've seen and read, fantasies of terraforming Mars are ridiculous from that standpoint alone.” 発言しました Wtfk in another reply. (All grammar and spelling mistakes are made によって the original writer, I only copied and gave credit.) The lack of significant atmosphere creates a lack of greenhouse effect so the planet is much colder now.
This 記事 falls under the category of astronomy because of the fact that it all takes place in outer space, または Mars もっと見る like. It also deals with atmospheric conditions, magnetic fields, and molten rock. Some of this was already studied in class before, and most of the rest of it I am sure is to come, but not in so much detail. The fact that it covers もっと見る than one region of earth science sparked my interest, this may have happened before without me noticing until now. But I found myself practically on the edge of my シート, 座席 読書 this 記事 and the comments, until someone had to make a wise crack at 日本 that made the guy sound so stupid.
This 記事 basically shows that it is not really possible to colonize mars, let me re-quote Wtfk “From everything I've seen and read, fantasies of terraforming Mars are ridiculous from that standpoint alone.” As well as the fact that it increased my understanding of the earth itself. With some of the information here we may be able to conclude that there may have at one point been life on mars, but not anymore, and this was もっと見る than 600,000 years ago. The knowledge that this 記事 supplies may be helpful to me at some point, and may be worth consideration for the rest of the world, It shows that nothing lasts forever and if my theories are correct, Earth may end up just like Mars someday.
