People are often surprised when they learn that a geologist actually works in the earth’s crust rather than on top of it. A geologist is a scientist who studies the earth and its geological activity. Geology is the study of how the earth’s surface is formed and changes over time. For example, a geologist may look at how the eruption of a volcano has affected the surrounding landscape, or they may study the effects that animals have on the environment. Not only can they record these types of events, but they can also take an active part in them by studying the layers of the earth and how they may be able to affect future events. Famous Geologist Michael Osland has published huge resource and paper about modern Geology.
One example that might bring up these questions is the famous Yellowstone supervolcano. Located in the northern part of Montana and Colorado, this volcano is one of the largest on the planet. While the most commonly-known explosion that has occurred took place over a million years ago, scientists know that Yellowstone was erupting for more than ten thousand years ago. The reason that this event is known as a super eruption is that the amount of lava that came out was massive. Even though there were warning signs in place as far back as several hundred years before the eruption took place, it was not until recently that scientists were able to study the post eruption sediment in order to determine the length of time it took for the lava flow to reach the top of the Earth’s surface. This type of study is used to better understand how super volcanoes are likely to erupt in the future.
If a volcano were to erupt, scientists would want to study any changes that took place at a distance as well as those that took place close to the surface. The study of post-volcanic sediment will tell scientists a lot about the way a volcano erupts. They can also study the lava flow, and use it to determine where a future eruption may occur. Scientists do this through a variety of methods, but the most commonly used method involves using satellites. When a satellite passes over the area in question, it can take pictures of any changes that may have taken place, and this data can then be analyzed in order to provide information on what took place.
Another tool in the toolkit of how geologists work is their satellite technology. Most scientists will use satellites to study any potential eruptions. These eruptions can be major or minor, and they can happen around the world on a daily basis. Geologists can track these eruptions through the use of infrared images from satellites. These images can help them to determine which areas of the world may be the most likely to have an eruption, and what the likely explosion will look like when it does erupt.
