Eurasian Plate

When the North American and Pacific Plates collided, the force pushed and curved the San Andreas forth towards San Francisco, California. As more and more aftershocks came, more powerful and large fires overcame the city. The fires wiped out much of the remaining people and structures. Overall, the main cause was the movement of plates around the Earth. The earthquake of San Francisco burned down many houses and buildings, making it…

Shale of the Appalachian Basin With various depositional environments and the understanding of sea level change, the Appalachian Basin formed by the collision of tectonic plates and sediment accumulation under the Earth’s surface. The Appalachian Mountains reveal subsidence belts, faulted marine sedimentary rocks and other geologic rocks in these tectonic settings. The Basin exists in the northeastern states of North America. This large rock formation exhibits collisional tectonics with modern…

Objectives Determining the age at death of a skeleton can be complicated and possibly difficult dependant on state of preservation, bones present, or archaeological context. By using measurements of the present long bones and the data that correlates the fusion times of the distal and proximal epiphyseal unions, an age at time of death can be narrowed down to a less broad range. While this measurement method is not completely accurate, dentition ageing techniques and cross referencing of the…

Mountains, and the Davis Mountains. The Rio Grande Rift expands from Colorado all the way to Chihuahua, Mexico. Earth surfaces began to pull apart around 30-35 million years ago. In this process, there were volcanic activity and moving of tectonic plates that have created much of what you can see today in the region. This includes many mountain ranges, the Rio Grande River, and Potrillo Volcanic Field. The Rio Grande Rift is still active and moves between .5-2mm per…

There are many methods scientists estimate earthquake probabilities. One technique is using the Global Positioning System (GPS) which permits geologist and scientists to make precise measurements of existing plates in motion. About 1.6 inches per year in the San Francisco area. The history of recent large earthquakes in a specific place helps determine the future of similar great shocks. Another way to estimate the chance of earthquakes occurring is finding…

Earthquakes Shira Miller Earthquakes are amazing natural disasters. An earthquake is a sudden and violent shaking of the ground. They are a big threat to people because they cause tsunamis, fires, and buildings to crumble on people. One of the biggest earthquakes was the great Chilean earthquake. The quake happened on May 22, 1960 near Valdiva (geology.com). The damage that the great Chilean earthquake caused (including tsunami damage) cost more than 500 million U.S. dollars (NOAA.gov). After…

Sharpe 1 Grace Sharpe Professor Fara Lindsay Earthquakes and Volcanoes Homework 1 June 15th, 2016 Sabancaya The volcano I choose to write about is none other than the Sabancaya volcano. It is located in the Andes mountains in Peru. This particular volcano is a stratovolcano part of a collection of three glacially covered volcanoes. The elevation of the Sabancaya volcano is 5967 meters high and it is the smallest of the three, however, it happens to be the most active. Volcanic ash and…

How the Continents Came to be One day while Zeus was down on the earth helping and looking around at all the humans, he met a very nice mortal woman. He went up to this beautiful woman and he started to flirt with her. “I don't think I have ever met a more beautiful woman in all the world” said Zeus. “Well thank you, you very nice looking man” answered the woman. The man then asked the woman if she would like to go on a trip with him. “This trip would be an a cross continent trip” said Zeus.…

Mount Saint Helens Devastates the State of Washington The 1980 Eruption of Mount Saint Helens was a moment to remember in history. The eruption of Mt St. Helens was devastating. The damage done costed lots of money. The eruption was huge and blew lots of ashes into the air and forest. Many people and animals died. The skies remained dark for days. It is by far the most destructive and violent volcano recorded in North America (Bagley). Mount St. Helens had been dormant for as long as we can…

Mt. Pinatubo, Philippines: Impacts and Human Actions The stratovolcano Mount Pinatubo began showing signs of erupting on the 15th of July 1991. Through a series of events Mt. Pinatubo erupted and effected the surrounding areas. Throughout this paper will be discussed the impacts, including primary and secondary, along with impacts changed by humans. Mount Pinatubo eruption was the second largest eruption in the 20th century, making it have many impacts not only locally but globally. Mount…
