The article has presented many new insights into planet Earth’s evolution. Lead author Dr Mark Kendrick from the University of Melbourne's School of Earth Sciences hypothesized that, “Inert gases trapped inside Earth's interior provide important clues into the processes responsible for the birth of our planet and the subsequent evolution of its oceans and atmosphere.” (Science Daily Dr. Kendrick and a team of researchers underwent an experiment, in which they collected serpentinite rocks from mountain belts in Italy and Spain. They found out that that the serpentinite rocks trap a large amount of seawater in their crystal structure and can be transported to great depths in the Earth’s mantle by subduction. Scientists understand the process of subduction as a process in which atmospheric gases are mixed into the Earth’s mantle, from such things as meteorites.
This finding is important because the study has indicated that the gases throughout Earth may not actually be from Earth. This study disproves the theory that gases must escape and cannot be stored in the Earth’s mantle, but gases can become trapped. The significance of this study has far reaching implications for future studies. Scientists can now experiment on these trapped gases and can try to discover the gases true origins, which can thus provide us with more information about our planet’s evolution of the oceans and the atmosphere.
From this article I have learned that our gases on Earth may not have come from Earth, but may have been transported here from space and got trapped in the mantle. This subduction process allows scientists to study the trapped gases to figure out when and where they came from. Before reading this article, I assumed that all gases are from Earth, but this article has broadened my prospective on Earths evolution. I think that we, the people of the planet Earth, are one step closer into finding the origins of our planet, the universe, as well as help understand how we as a people have come to be where we are in the universe.

I thought this summary was very well presented. Alex was very detailed and focused on the main subjects. It was easy to read and was organized very well. One aspect that I like that Alex had presented well was when he stated that the serpentine rocks had trapped salt water in the crystal that allowed the gases to reach the earths mantle. Another well presented reason was when Alex said that some of the gases wee unknown and were probably not from this earth. The third well presented fact was when he stated that his study disproves the theory that gases must escape and cannot be stored in the Earth’s mantle, but gases can become trapped.
Alex could have done a lot things better maybe if he got some definitions or some extra data would have been good. I would have expected Alex to have down a little background research. Also if Alex could have just summarized it easily in one paragraph, that would be very nice.
One thing that had shocked me when Alex said that the gases that made up the earths mantle may have not been from this earth. The gases that formed the earth according to Alex had come from meteorites. This is what shocked me and made me very interested in Alex’s article.
I think Alex did a good job presenting this article. It was a difficult article to read, but he did an excellent job summarizing it and made it very understandable. The organization of this summary made it easy to read and comprehensible. The events were written in the way they took place, which I think is very important. Another positive aspect would be that he focused on the main topics. The article had a lot of detail, which made it a little complicated to read, but Alex’s summary focused in on the imperative parts, which I think is important. He gave enough detail to tell what the article was about. Another part that I like is that he focused in on the serpentine rocks, which I think were the essential part of the discovery. By stating that the serpentinite rocks trap a large amount of seawater in their crystal structure and can be transported to great depths in the Earth’s mantle by subduction is the key to understanding this article. Another positive aspect would be that he included the quote by Dr. Kendrick. I think he chose an important quote to include and it definitely helped in the summarization. The quote was also essential to understand and he did a good job of explaining it.
ReplyDeleteTo improve this article, I think he should’ve added definitions to some of the words. The article had some words I didn’t know, so I think if Alex explained what some of the words meant it would’ve been helpful. Another aspect I would improve would be to describe the implications for future studies. He stated that there will be implications but he didn’t state what kind, which I think would’ve been useful and got the reader to further understand the article.
This article was very intriguing to read because I’ve never heard of these discoveries before. Now I have a better understanding of the Earth’s revolution and its possibilities. It is fascinating how these discoveries about the earth are still being made today. I think this is a topic worthy of note because it is interesting how scientists will have to change much of their theories now to support this discovery.
Alex did a wonderful job presenting this topic into a well-written summary of the Salty Water and Gas Sucked into Earth’s Interior Helps Unravel Planetary Evolution. In this review, I enjoyed that Alex presented his information orderly and that the topics from sentence to sentence linked and kept the summary interesting and easy to follow. In the summary, Alex shared most of the important details from the article with great depths; such as he presented the experiment in which serpentine rock was proven to collect seawater into the crystal structure. Another aspect of Alex’s article was that he incorporated information by actually using the article.
ReplyDeleteThis summary was very well presented however couple things could have improved the summary of Evolution. Alex could have included definitions to make the article easier to follow. Some people may not understand the summary or article without knowing the terms the article used. I think it would have been easier if Alex used the article and summarized how long it took or what they needed to find the information needed to prove the statements about evolution.
Before reading this article and the summary that came along with it I didn’t know that a rock such as serpentine could absorb a large amount of seawater. “The serpentine rock from mountain belts Italy and Spain is found to trap large amounts of seawater in their crystal structure and can be transported to great depths in the Earth’s mantle by subduction.” States Br. Kendrick. I did not know this information and because of this summary and the article I have just read I am now more informed of the salt water and gas that is sucked into the Earth’s interior.
I belive that Alex did a very good job in summatrizing the article. He borught across the main points, and did not add in any unneccessary information. Although the article was hard to read, his summary helped me understand it a lot better. I also liked how Alex went into depth about the experiment, which gave me a clear idea about what the article was talking about. Alex also helped me understand the importance of these discoveries.
ReplyDeleteI think that Alex could have gathered some background information, and talked more about the gasses, and other experiments that helped this study. I also would have liked it if Alex talked more about the future studies, and what these discoveries could lead to.
I think this was a very interesting article. It gave me insight on a topic that I knew nothing about before.
I thought Alex did a good job in summering this article. I liked how Alex included Dr Kendrick research and his thought about this topic. Although the news article was a little tricky to read and understand, I thought that 1Alex did a great job summarizing it and really go all the main points. Alex’s summery was fairly easy to read which made it understandable .I also liked how Alex included all the great detail about serpenrinite rocks and how they were found and their importance to the discovers.
ReplyDeleteI thought that Alex could have expanded more on Dr. Mark Kendrick’s experiment and his process that he had to go through to get his research. I also thought that Alex could have explained in more detail on some words like serpentinite rock and their crystal structure. He could have talked about them more. Alex could have expanded more on how the significance of this trapped gases can far reach the implications for the future studies.
I thought that this was a very interesting article. This was the first time I hear about this. I found that it was very interesting that salt water and that have been sucked into the earth’s interior can be useful information to our planet evolution. This article really opened my eyes to the earth evolution. I was very interested on this topic.
I thought that Alex did a great job presenting this article right off the bat. From what I could see, it seemed that the article was a very hard read and I think he did a good job summarizing it very quickly and easily. I also thought that Alex did a great job going into detail about everything he was explaining, which sometimes isn’t easy to do. He did a really awesome job explaining things also, making it easier for me to read and understand.
ReplyDeleteI think that Alex could’ve probably done a few things to help others better understand what he was trying to say. Although I think he did a great job overall, he could’ve defined some of the words that we was using to explain his summarization, helping the reading understand even more than he or she would have. I also think that Alex probably should have added more of what he thought about the article. I thought his points were valid and he had some great ideas, but it seemed very straightforward and I wish I could’ve gotten some more on his opinion.
I thought that this article was very fascinating and I thought it was really cool that Alex talked about a better understanding of our origins, because it also appeared to me to be very cool. From this article I learned that there are definitely more ways than one to explain the origins of our universe, and now we just have to find out which one is correct.
