The phenomenon that is the Siberian arctic craters is a weird one, because no one knows how they form exactly. They are said to have been hidden as lakes and then blow up from the gas build up and are kind of like cryovolcanoes that are found elsewhere in our solar system. They do not shoot lava out of themselves but rather icy objects and gases. This has to do with our module because it is dealing with the mass wasting and is almost like a landslide sink hole. 10/1/2020 08:23:01 pm
In Siberia, there are multiple occurances of craters appearing. It is not officially known what causes these craters, but scientists think that they occur when methane and carbon dioxide escape from being trapped by exploding out. This article pertains to this module by showing how unexpectedly the Earth can change. If these craters are caused by the climate getting warmer, me may need to be more cautious and help slow down global warming.

Scientists believe that the series of craters in Siberia were formed from natural blasts of methane and carbon dioxide gas trapped within mounds of dirt and ice. A volcanic mechanism called cryovolcanism is also believed to have caused the massive crater. Cryovolcanic eruptions are eruptions that take the form of frosty mud or slush rather than fiery molten rocks. The blasts of methane and carbon dioxide gas that caused the craters are thought to be a product of climate change as this phenomenon does not normally occur naturally on Earth. Melting of the ice caps caused by climate change may make this unnatural phenomenon occur more often in the future. This article is relevant to Module 5 because we are learning about mass wasting and this article is about how the craters in Siberia were created by volcanic mass wasting.

Craters have been discovered in Siberia, seemingly at random, since 2014. Scientists believe these craters are caused by methane and carbon dioxide gases that are trapped within dirt and ice and cause a blast within these mounds. These craters are becoming more common as the climate warms. This relates to the module because it is another example of how the climate getting warmer causes more and more types of natural disasters. We need to do more in protecting our Earth's climate to prevent even more types of natural disasters to form.

In Siberia, scientists believe that there are craters that have been formed when methane and carbon dioxide gases get trapped and they explode. There are also rumors that a volcanic mechanism cyrovolcanism caused some of the craters. This article relates to the module because global warming is causing more problems everyday. Environmentally and physically. These crates are caused from the heat of global warming. With global warming occurring, We need to do our part in protecting the Earth or more disasters will happen like the craters.

Scientists theorize that craters are being form when the gases, methane and carbon dioxide, that are trapped release pressure. Studies point to an occurrence known as cryovolcanism in which eruptions are frosty mud rather than fiery molten eruptions. A reason for these eruptions are a form of mass wasting known as ice wedging from the lakes which is what is covered in our module.

This article reminds me of our module by describing how global warming can and is causing more natural disasters. The theory is that the crater was created by an explosion of carbon dioxide and methane gas. While it is still a question that needs answers, it makes me question if this kind of explosion is confused for an earthquake or if it happens more subtly. Leave a Reply. |
