Take a look at this article. Ever wonder where your gas comes from? Remember, all posts should be at least 5 sentences long and filled with info. Extinction!
a volcanic eruption possibly caused a mass extinction in underwater oceanic life. the eruption depleted all oxygen from the ocean and caused serious chemical changes in the atmosphere as well. studies on this event are crucial because it could possibly happen again. the event occurred when temperatures were high, and as global warming is a serious issue, the same event could effect us. it is considered a major extinction, not as large as the mass extinction of the dinosaurs, but of the same importance. studies will help us discover more and possibly prevent this from happening again. this article was very informative and showed me that major extinctions occurred not only on land, but in water as well.
I found this article really interesting. Mainly the fact that 93 million years ago there was undersea volcanic activity that caused a mass extinction of marine life. The eruption also buried a thick mat of organic matter on the floor of the sea that became a major source of oil. Also when the lava fountains erupted it altered the chemistry of the sea and it very could have altered the atmosphere too. After the volcanic eruption the temperature and carbon dioxide levels on Earth dropped. 10,000 to 15,000 years after the eruption the carbon dioxide levels went back up. The fact that an undersea volcanic eruption could cause that damage is an amazing natural phenomenon. This article is informaing and it taught me that undersea extinctions are as possible as land extinctions.
This is cool. I was unaware that underwater volcanic activity could effect the world on such a large scale. If this event didn't happen we might not have any oil at all right now. Also we would probably have weird massive creatures roaming through the sea. Some ancient creature might not have died off which would have altered the food change which would have altered the creatures of today. it is amazing that these changes in the Earth can happen so rapidly.
I think this article is very cool. I never new that an underwater volcano could change the climate. I also didn't know that the eruption buried a thick mat of organic matter on the sea floor that became a major source of oil. So if it wasn't for that under water volcanic eruption then there might not be any oil on earth. If this event didn't occur than everything would of been different we would of had different types on animals. The article taught me a lot of things.
A new study found that undersea volcanic activity could have casued a mass extinction of marine life 93 million years ago. Also, it could have become a major oil source. This is interesting that oil could result from an underwater eruption. This erutption could have possibly altered the chemical make-up of the ocean and maybe even the atmosphere. At first the animals and plants thrived off the nutrients released of the eruption, but then when the animals died, they depleted the oxygen in the water. I did not know that an underwater volcano could possibly have such a big effect if it erupted. I agree with annika that it is important to study this occurence becasue it took place during a warm period and right now global warming is a major issue.
A undersea volcano is said to be responsible for the death of some marine life about 93 million years ago. The lava fountain erupted altering the chemistry of the sea causing the death of many species of marine life. This is said to be one of the big mass extinctions of Earth's history, most were some kind of impact, but this one is earth bound. since the climate was so warm, the oceanic current was slow and buffered a magmatic pulse and went haywire. This can show that narual disasters can be more harmful to humanity then what people think that what humans do to the envirment can do.
This article is actually pretty interesting. To think that thousands of years of extinction was blown up by a volcanoe seems pretty unreal! Also, it is crazy to think about the ocean's temperature is dropping all at the same time! I had no idea oxygen could have that type of effect. Lastly, 93 million years ago is a longgggggggggggggggg time... like really long.
This article is very interesting. It is also very scary. Hearing that "underwater volcanoes triggered a mass extinction of marine life and buried a lot of organic matter on the sea flood about 93 million years ago" is so frightening to hear! I don't want that to happen to us haha. That would be unfortunate for us but i think i would live because i would build an house on the moon and live there :)
I found this article very fascinating. The fact that over 93 million years ago a single underwater volcanic eruption led to extinction of many species of marine life at the time. One of these eruptions could change the chemical basis of the sea or even the atmosphere. The eruption had two effects on the marine life nutrients were released into the ocean and caused major growth. When all the marine life died and the decompostion fell towards the sea floor and cause oxygen depletion. This is very interesting that just once eruption can cause so much distruction.
This is all very fascinating. That over 93 million years ago a underwater eruption caused a extinction of most of marine life. "Of the big five mass extinctions in the Earth's history, most of them were some kind of impact with the planet's surface," said Turgeon. This mass extinction made two things happen, nutrients were released and a large amount growth happened and when the mass of organisms died and the decomposition caused oxygen depletion. Its amazing that one eruption can cause so much change in the world.
Every body really did a great job! I like it when you comment on others' posts and reply- It shows me that you are really thinking about what other people say.Great Job!
I think it is very interesting that a volcanic eruption could cause mass extinction, the result of anoxic which is result of the underwater volcanic eruption, and that the temperatures and carbon dioxide levels dropped. Also, the fact that 10,000-50,000 years ago the carbon dioxide levels rose again. Because of this we should be worried about our organic life on the earth.

I found this particular article very interesting to read. It came very suprising to me that millions of years ago oceanic volcanic eruptions killed so much marine life in the ocean. The remaining matter and stuff from the eruption left a think layer of oils and things on the seafloor which harms marine life. When the volcano erupted it altered the chemistry and the waves of the sea. It amazes me that one eruption can cause so much damage on earth. I read Matt Meyers comment, it was awesome.
According to a new study, over 93 million years ago underwater volcanic activity caused a mass extinction of marine life and buried organic matter on the sea floor. It caused an extinction of many species in the marine environment. The eruption, unlike most of the other mass extinctions, was a natural phenomenon. This research could not only help prove a mass-extinction theory but help us study the effects of global warming.

This article is preety interseting i didnt know that a vocanoe could do so much damage
