The Mass Extinction Of Dinosaurs

Decent Essays

As young kids, we spent no shortage of time learning about all of the animals that have inhabited planet earth since the origin of time. And while there are tons and tons of fascinating species in the world, there was always one topic in particular that stood out to all of us- dinosaurs. Whether it was just the sheer concept of another species living on the earth before we were even alive, or the tales we were told about their incredible strength and size, we were transfixed by dinosaurs, specifically their disappearance. One thing that never quite made sense was how such an exceedingly powerful group of animals, that lived in what seemed to be every corner of the world at one point, could just up and vanish one day. The answer of …show more content…

There are, however, several plausible causes for each extinction event that either by themselves, or with the help of other factors, triggered the mass extinctions of a numerous amount of life forms. One of the largest supposed causes of many mass extinctions are flood basalt events, which are the result of a giant volcanic eruption, or series of eruptions, that coat large stretches of land and the ocean floor with basalt lava. While when small, these events can be seemingly harmless, large eruptions can produce dust and aerosols, which stop photosynthesis and cause food chains to collapse both on land and at sea. In addition, flood basalt events emit sulfur oxides, which precipitate as acid rain and poison many organisms, along with carbon dioxide, causing sustained global warming once the dust and aerosols dissipate, both of which aid in the further collapsing of food chains. There have been eleven situations documented so far where flood basalt events have had either a direct or indirect impact on the occurrence of a mass extinction. Next in line on the long list of possible causes are sea-level falls, the exact opposite of sea-level rises, which can actually be extremely beneficial to the environment. A sea-level fall involves a large decrease in the total volume of water in the world’s ocean,
