Why Use Expository Essay Topics About the Ordovician-Silurian Mass Extinction?

Why Use Expository Essay Topics About the Ordovician-Silurian Mass Extinction?The Ordovician-Silurian mass extinction event is known to have occurred millions of years ago. Since this time, there has been no life on earth. This event is believed to be a direct result of the disruption in the earth's atmospheric circulation. One theory put forth by some researchers suggests that the Earth's mantle was pulled under due to the movement of a volcanic mountain.Fossil hunters believe that animals were scavenged after a huge eruption erupted from the crater in the center of the Earth. At this time, most of the continents were under water. The regions at the equator were then subjected to intense heat, which caused many animals to drown or freeze to death. Researchers believe that even when animals survive the Ordovician-Silurian mass extinction, they are unable to move far enough to another place where there are more resources available.The first essay topics have already been done for this event. While there are many theories that surround this one event, it still remains a mystery. Researchers now have many new theories that do not center around volcanic activity.Some researchers believe that the Earth got a lot hotter in the days leading up to the volcano eruption, and this volcanic activity could have caused another earthquake in the area, which led to the volcano erupting. A second shockwave created by the earthquake would have been picked up by the mountain. Researchers believe that a shockwave would have traveled at the speed of sound, which would have damaged the structures.While there was a cooling down of the Earth's crust that happened afterward, it is thought that other parts of the earth's crust were pushed and pulled in the process. The neck of the volcano grew further out into the distance, creating the post volcano. This created cracks in the crust, which allowed the oxygen and other gases to escape.Because of the continuing studies of these essay topi cs, a lot of new information is being discovered. It seems that many areas of the earth experienced different types of events leading up to the devastation of the Ordovician-Silurian event. It seems that the animals and plants did not know how to cope with the sudden change. Some could not move, while others froze to death or drowned.These essay topics may have been a great way to help people deal with their daily lives. Because of the unanswered questions surrounding this event, some people are looking for answers on how to help the environment. Everyone deserves a second chance at life.Because of the research and information coming from these essay topics, many people are helping the earth in ways that they never realized they could. These are just a few examples of the facts that are being looked into. Regardless of what caused the extinction, everyone can get excited about the fact that some new things are beginning to happen.
