According to the article, undersea volcanic activity which occurred 93 million years ago led to an extinction of marine life. The undersea volcano left behind organic material on the sea floor. This natural phenomenon became a major source of oil. At the time, the climate was very warm and the current was slow. The process that occurred led to black shale deposits which became "source rocks" for the petroleum produced today. The eruptions that occurred allowed nutrients to be released into the ocean which caused plants and animals to grow. When the plants and animals eventually died, they sunk to the bottom of the ocean where they decomposed. Because of the oxygen depletion and and carbon and CO2 which were found in the organic matter, oil was produced.
In this article, undersea volcanic activity occurred 93 million years ago. It certainly caused an extinction of several species in the marine environment. Since the climate was so warm back than, the oceanic current was very sluggish. According to their research, the eruptions preceded the mass extinction by a geological blink of the eye. The event occurred within 23 thousand years of the extinction. The oxygen depletion and carbon and CO2 which were found in the organic matter and oil was produced.
about 93 million years ago there was a very large underwater volcano eruption. In the article it says that there were large fountains of lava. They believe that this caused a large change in the chemistry of the sea and possibly the atmosphere. All of this made it so that plants and other organisms could grow. through this it after all of the animals ate all of their waste fell to the bottom of the ocean causing a depletion of oxygen in the atmosphere. because of this it causes a large carbon dioxide cloud. it then caused the ocean to loose all of its oxogen. through all of the volcanic eruptions it caused carbon and CO2 to be release and it was all stuck at the bottom of the ocean and used some of the carbon dioxide and formed oil and brought down the levels of carbon dioxide in the ocean and the atmosphere.
93 million years ago undersea volcanic activity triggered an ample extinction of marine life; this left a mat of matter deposited onto the sea floor which has now become a major source from which we get our oil. Turgeon and Robert, scientists from the University of Arizona concluded that the lava fountains that erupted many years ago changed the makeup of the ocean floor and possibly some of the atmosphere. Almost all of the five mass extinctions that have happened have had some effect on the surface of the earth, it was concluded that this extinction was all natural. The temperature of the water a long time ago was very warm with a sluggish current, when it cooled off and the current sped up then this caused a change in magnetic activity, which causes seismic activity. Also that mass extinctions have side effects, such as anoxic events. These are caused indirectly by underwater volcanoes.
Accoding to the article, about 93 million years ago, a volcanic eruption in the ocean caused many animals and organisms to die, due to the intense violence that the volcano contained. A few scientists say that this even killed a few species, which is worthy of a major event in earths history. What happened was that the nutrients were released, which allowed alot of food for animals and organisms. When these organisms died, they decomposed and fell towards the sea floor which caused further oxygen depletion. This helped increase the carbon dioxide levels on the floor where the eruption took place. The reason for such a mass destruction was the build up of carbon dioxide.
I found this article very interesting. It stated that around 93 million years ago, there was a volcanic eruption in the ocean that caused a mass extinction. Some scientists even say that is may have killed some species. Most mass extinctions are caused by things that hit the earth but this was completely different. They also state that is was not as bad as the extinction that killed the dinosaurs, but it is definitely something that does not happen often.
This eruption caused a lot of marine life extinction. I think it is so sad what it has done. It has wiped out many animals and killed millions of are sea life creatures. I really found this article interesting, but also very tragic. They also stated in this article that is was not as bad as the extinction that the dinosaurs that makes me feel better about the whole thing.
Because of volcanic eruptions in the ocean about 93 million years ago, there were mass extinctions of animals and animal species. As the organisms decomposed on the bottom of the ocean sediments compressed the bodies until the carbon became coal and natural gasses.
The article states that about 93 million years ago, an undersea volcano erupted. The ocean water was more sluggish because of the earths warmer climate which buffered the magma but the eruption was still devastating. The eruption was so massive that it caused the extinction of several species of marine life in the aera. However, the organic matter that settled on the sea floor eventually turned into the oil we used today. This mass extinction was different than the other five big extinctions in that it was caused by a volcano instead of something hitting the Earth.
This event caused an extinction of animals similar to the extinction of dinosaurs long ago. The ocean buffered a magnmatic force due to the heat of the climate but then went crazy. his caused the oxygen to be dragged to the bottom of the ocean along with organic matter that were made into rocks. because of the continuation of volcanic eruptions, nutrients were released which caused growth of plants and animals. once these animals died, their bodies fell toward the ocean floor which caused more oxygen decreasing.This helps the study of global warming.
I think this article was very interesting. It was about what and how much of the sea life the undersea volcanic activities hurt. The good thing is that it doesn't happen very often but overtime when it does, there's always an impact with the planet's surface. There were also many side effects to this event. Temperatures and carbon dioxide levels dropped and the organic matters were locked at the bottom of the ocean which turned into oil.
