America has changed through the years in many ways. Medicine has improved, average standard of living has risen, and the overall quality of life has changed drastically over the course of time. Yet, these are all short-term ideals when taken into the whole picture. Although all of this is important, to truly understand the actual face of America, we have to think farther back than a few hundred years. The face of America can best be portrayed in thinking about how America looks the way it does. Questions like “How did the Rocky mountains form?” or “Why are the Great Plains located where they are?” These types of questions are important because once you figure out why certain areas have the qualities that they do, it becomes simpler to pinpoint why Americans live and react the way they do. For example, not just Americans but humans in general desire a marine climate area, typically close to a water source, and moderate temperatures that do not vastly fluctuate. This is why so many people are located on the coast near California or Florida. What becomes interesting is that if the tectonic plates hadn’t shifted the way it did, and perhaps broken apart differently from Pangaea, then America wouldn’t look the same as it does now. America would have more or less land for people to cultivate and live on possibly changing the areas of higher population or common wealth depending on if the new land was useful in anyway. All this ties into why America looks the way it does or the “face” of America.
Since California had previously been mentioned, it is a great place to begin explaining the complex geological impacts starting with the San Andreas Fault. The San Andreas is what geologists know as a strike-slip fault, meaning that when two pl...

...oncerning the way people live and interact in America today. From why California has so many earthquakes with the San Andreas Fault, to the formation of America’s national treasure Yellowstone Park, and even why certain crops are located where they are, it is important to know just how geology affects the United States. There are many different ways how America has changed throughout time, but the evolution in geology is the changing face of America.

Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...

The earth was formed 4.6 billion years ago from the nebula cloud of gas that created the Sun and the other planets present in the Solar System. Ever since then, the earth’s surface has been constantly changing; the primary reason for this is because of tectonic plates. Even though, humans have existed on Earth for around 200,000 years, humans have been responding to the challenges of living on a planet with a constantly changing surface by using scientific evidence and technology to help them adapt to a constantly changing environment.
On Sunday September 20th The class of Geog 2020 went on a field trip to observe bio-physical features of the Ottawa area. Our first stop was to Erskine Johnson Elementary School in Kanata where there is a large visible outcrop of precambrian rock in the school yard. Our next stop was to The March Highlands Conservation Forest, a forested area that features beaver ponds and sand stone beddings. Next we moved on to the Crozier pit, a mining sight near Renfrew that features a large precambrian marble outcrop and deep pit with visible sediment layers on a the outside ridge. Our last stop was the Fourth Chute of the Bonnechere river which is the site of the Bonnechere Caves. Before going into the caves my group investigated the fossil covered rocks down by the by rapids of the Bonnechere river. And then we went on our guided tour of the beautiful limestone Bonnechere Caves. In this paper I will explain and elaborate on my observations.
Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt. (Pitman, W.C., 2007)

The state that I had picked out for this assignment is California. What is the plate tectonic setting of your chosen state? What natural resources are mined or extracted there? What erosional or depositional settings such as, mountains to coast found in your state? Also, what is the geologic history of your state? All that and more will be discussed in the following text.
Rising of the earth’s crust is responsible for producing earthquakes, Submission of report for publishing.
Earthquakes are natural disasters that are also referred to as a ‘quake’ or ‘tremor’. It is classified as a geomorphic hazard, which are elements of the physical environment that can cause damage, (economically and environmentally) such as Volcanoes, Tsunamis, Landslides etc. Earthquakes have been around for thousands of years but no one had properly understood the concept. Not one person, but a crowd of geologists and scientists had discussed this hazard and identified what it actually. There have been some weird beliefs about earthquakes such as earthquakes were caused by air rushing out from caverns underground.
