How Do We Know About Volcanoes?
Do you want to learn about volcanoes and how they get formed? Here is a brief look at the history of volcanoes. We see volcanoes as they erupt and this allows us to have an idea of how life has come to exist on earth. There are many forms of life but they are all dependent on volcanoes for their existence.
A caldera is a place where two mountains have collided. The mud, rock and soil that are below these bodies get mixed together and eventually becomes a rock or mud again. These eruptions have often been caused by a volcanic vent. This makes the volcano known as Tambora, which is the largest eruption in recorded history. Tambora’s eruption was also responsible for a lot of mortality on the European continent.
A volcano’s appearance depends on its activity and its location can help scientists understand when and how it was formed. During the eruptive phase of volcanoes, vents produce gases and materials that allow lava to be carried out to the top of the volcano. Scientists believe that these gases and materials go back down the volcano which helps to keep the volcano active.
The first activity that caused volcanoes to erupt is the birth of a volcano which explains why early humans had no idea of how this would happen. It started when rocks were being ejected into the atmosphere from volcanoes and those rocks then travelled up to form mountains. Those mountains that we see today help to shape the Earth and therefore determine the evolution of the Earth’s crust.
Scientists believe that the early humans were not aware of how big the Earth really was and therefore were unable to determine where to build a residence. They built dwellings in caves, under mountain ranges and in a great lake that created great seas of mud. The mud allowed them to live comfortably and this is where agriculture began to occur.
At some point in time, some kind of major volcanic eruption caused the seas to rise and the seas were destroyed as a result of great floods. As a result of this, the mountains were moved causing the rivers to flow higher. After that came another type of volcanic eruption and this time, the continents collided. This allowed the sea levels to increase causing a flood that killed many people.
When volcanoes no longer provide the resources that they once did, they begin to grow and now we see mountain ranges and other formations as a result of eruptions. Once the resources are depleted, the volcano gets silent as it is covered in lava. This explains why we do not hear much about volcanoes in our day to day lives.
The volcano history is fascinating and provides insight as to the creation of life on earth. Scientists believe that there are many areas of the world that have still not been discovered and that scientists are still trying to learn more about the history of volcanoes. These studies are vital in helping researchers create bridges between the past and present.
