What do scientist think caused the permain extinction?
Most recent (read this year) studies suggest that massive volcanic activity, caused this major event.
How do scientists think the activity of the Siberian Traps changed the chemistry of the oceans?
Scientists believe that the activity of the Siberian Traps, a large volcanic province, released massive amounts of greenhouse gases and sulfur dioxide into the atmosphere, leading to global warming and acidification of the oceans. This likely caused significant disturbances in ocean chemistry, such as increased levels of carbon dioxide and ocean acidification, which could have had major impacts on marine ecosystems and biodiversity.
Does the Antarctic plate have hot-spots?
No, the Antarctic plate does not have hotspots. Hotspots are areas of volcanic activity caused by mantle plumes rising from the Earth's core, and the Antarctic Plate is mainly a stable tectonic plate with no current volcanic activity.
What event do scientists think may have caused the mass extension at the end of Paleozoic?
Scientists believe that the mass extinction at the end of the Paleozoic, particularly the Permian-Triassic extinction event, was primarily caused by a combination of volcanic activity, climate change, and ocean anoxia. The Siberian Traps, a massive volcanic region, released vast amounts of greenhouse gases, leading to severe global warming and a decrease in oxygen levels in the oceans. These factors created a hostile environment that resulted in the extinction of approximately 90% of marine species and significant terrestrial life loss.
What makes scientists think that the gullies was not formed by volcanoes?
Scientists believe the gullies were not formed by volcanic activity due to their distinct characteristics that resemble erosion processes caused by liquid water. The presence of features like branching patterns and flow dynamics aligns more closely with the action of water rather than lava flows. Additionally, geological studies and the lack of volcanic materials in the vicinity support the conclusion that these formations are primarily the result of sedimentary processes, likely influenced by climatic factors.
What natural factors do scientists think might be causing climate change?
There are no natural factors that scientists think are causing the present climate change. It is now clear that global warming is caused by deforestation and the burning of fossil fuels (coal, oil and natural gas).
What did scientists think the Arizona crater was made by?
A volcanic steam explosion was earlier believed to be the cause.
How do you think scientists were able to discover Earth's plate boundaries?
Scientists were able to discover Earth's plate boundaries through a combination of studying earthquakes, volcanic activity, and the movement of continents over time. By analyzing these phenomena, they were able to map out the boundaries where tectonic plates meet and interact.
Why do scientists think Mars was once like the Earth?
Scientists think Mars was once like Earth due to evidence of past water activity, such as dried up river channels, shorelines, and minerals that can only form in the presence of water. Additionally, Mars has a similar geological history to Earth, with evidence of plate tectonics and volcanic activity. These clues suggest that Mars may have had a more Earth-like environment in its distant past.
What are the phenomena that result from characterictics of earth layers?
if i understand the question corectly then here are some ideas volcanic activity earthquakes tsunami(caused by earthquakes commonly) and im not sure about this but i think hotsprings may be linked somehow
Why do scientists think may have caused the bizarrebahavior exhibited during the?
te withcraft
Why do some scientists think that sunspot activity affects global climate?
Because of the Solar Wind.
