Dear US Geological Survey, I think that you should accept Alfred Wegener’s Theory of Continental Drift. There is a large amount of realistic evidence to prove that this theory did occur. Wegener’s theory is that all seven continents were once joined into a supercontinent called Pangaea. He believes that after continents were in that supercontinent, they gradually moved apart over more than a hundred years ago and will continue to move in the future. This Theory of Continental Drift is supported…

About 60% of the territory is mountainous, apart from the coasts. Puerto Rico offers Varity of amazing rain forest, deserts, beaches, caves, oceans and rivers. Puerto Rico has three major Geographic regions: Mountainous interior, coastal lowlands, and the karst area. Mountainous interior is formed by a chain of central mountains generally known as Cordillera Central, The largest mountains are Cerro La Punta (1,338 m) in Jayuya; Rosas (1,267 m) found between Jayuya and Ciales, Guilarte (1,205 m)…

Rockbolts as a ground control technology are just one in the very long list of ground control technologies that exist in mining and civil applications. The simplicity and reasonable cost associated with rockbolts are the primary driving forces for the research causing their wide variations for numerous public and private uses. The ease of calculation and implementation also makes rockbolts a go to option for engineers who would rather spend more time calculating other variables during a job…

Relative dating and radioactive dating have semi major difference in determining the age of fossils. Some differences would be the techniques and methods used to determine the age of a fossil. Also another difference would be the process and the different types of dating that will work to find the age for that fossil. As well as the many terms that goes in the processes for dating fossils. Relative dating does not give an actual date for the fossils. Relative dating is used to organize…

The Formation of Australia Although Australia has the least surface area compared to other continents, it does have a long geological history. Australia is formed by many geological elements resulting in the present-day Australia. Continental drift is the movement of the Earth's continents shifting (Appearing to be 'drifting') on Earth's surface. There have been many supercontinents, throughout history, which had existed on Earth's surface for millions of years. Supercontinents are a cluster…

Throughout time, many ideas have come and gone about the movement of continents, some saying that it’s true, and some saying that it’s not. One theory, though, is the most well known and the one most people believe to be true. This is the continental drift theory, created by Alfred Wegener, a German meteorologist. Alfred Lothar Wegener was born on November 1st, 1880 to a German family. He was the youngest child of Richard and Anna Wegener. He had 2 siblings, a sister named Tony Wegener, and a…

1. Do some Internet research on Chevron’s use of seismic imaging technology. Briefly explain how it works and how it has helped Chevron discover new oil and gas reservoirs. Seismic imaging is a tool that reflects the waves off the underground rock structures to show the possible crude oil and natural gas that are present underneath. People use the ultrasensitive devices that is called as geophones to capture the sound waves as they echo underneath the earth. So by studying those echoes,…

recent research and current events in geology. Most of the content being shown focuses on geology. However, some posts will be heavily focused on biology, chemistry, or physics since geology can rely on knowledge in any of those disciplines. An example of this is the research on “Sulfur-oxidizing bacteria prior to the Great Oxidation Event from the 2.52 Ga Gamohaan Formation of South Africa.” That research paper involves chemistry and biology in addition to geology since it is referencing the…

1) Describe the two technological advances that have made it possible to better understand the dynamics of the Earth 's mantle. Two technological advances that have made it possible for scientists to better understand the dynamics of the Earth’s mantle are seismic snapshots and computer modeling. Seismic snapshots enable scientists to determine the temperature and density of the mantle. When an earthquake occurs vibrations are put into motion which create waves that can be detected by…

The White River Badlands, located in South Dakota, are a national park known for its heavily eroded land and a harsh train that has been developing for millions of years. This has led the land to develop greatly over time, along with encapsulating different species that lived in the land over the years. These species, over time, have been engraved in the stone, leading it contain and immense amount of paleontological aspects. Because of this, Badlands national park has been considered the…
