Geological history of Earth

To some, much of what caused the effects was the burning of fossil fuels. The “Sant Ocean Hall” Exhibit states that the Anthropocene is “a new geological epoch that started with the Industrial Revolution” (“Sant Ocean Hall”). Similarly, Steffen et al states that “what made industrialization central for the Earth System was the enormous expansion in the use of fossil fuels, first coal and then oil and gas as well" (Steffen et al 616). Both of these claims compare to be the same…

I have been interested in geological sciences since I was a child. Growing up on the Caribbean island of St. Lucia, my mother was a member of a heritage and nature group called The Natural Trust Foundation and as a result she would take me along to the different programs and excursions. One moment in particular that stands out to me was a visit to the volcano in Soufriere, located in the southwest part of the island. Just to mention that St. Lucia has the world’s only “drive-in” volcano. Our…

There are many geological hazards that could affect the Portland Metro area in the near future, but the three most devastating would be Earthquake, Volcano Eruption, and a landslide. There has been numerous rumor about the “big earthquake” that is long over due for the PNW. The earthquake is estimated to be a nine magnitude, which means it’s going to cause a lot of damage to Portland and could even make Portland disappear. An earthquake is generally formed when the underground suddenly breaks…

atoms. Atoms of tholins in the atmosphere can affect both the colour of haze and the ground of Pluto. The second part contains the geological features on Pluto, including two distinctive regions: Sputnik Platinum and Tombaugh Regio. In this part, further interactions of the atmosphere and geological activities on the surface are discussed, as well as how these geological features affect the colour and brightness of the overall appearance. Introduction Pluto is a tiny dwarf planet lying at…

of last non-avian reptile species called dinosaurs vanished from the earth. The extinction of this huge animal is a never-ending topic of interest, the mass extension of dinosaurs occurred over a very short geological period. Keywords— Non-Avian Dinosaurs, Mass extinction, Dinosaurs extinction theories; Asteroid impact; Volcanism; I. INTRODUCTION Dinosaurs are the certain group of reptiles which influenced and ruled the earth for more than 160 million years, which are descendant from the…

contain important information about the history of the earth. They contain fossils which can teach us about plants and animals of the past. They also offer clues to what the original rock may possibly be. An astounding amount of minerals is also found here leading to the mining industry found in this area. Various paths and bodies of water provide transportation through the escarpment but also from one place to another. There is a good amount of culture and history found here such as the…

Discovered in 1930, by the American astronomer Clyde Tombaugh, Pluto was thought to be the farthest, newest and smallest known planet in our solar system. Pluto, for 75 years would be thought of as the ninth planet in our solar system. It wasn’t until the discovery of Eris in 2005 that astronomers began to question what defines a planet. After the discovery of Eris and other celestial objects such as MakeMake, Pluto along these new discoveries have been defined as dwarf planets. They are…

communicate the founding, expansion, preservation, and unification of the United States with colossal statues of Washington, Jefferson, Lincoln, and Theodore Roosevelt.” Mount Rushmore is a sight to behold, but how was the formation formed? What geological processes happened over time to form the peak of Mount Rushmore…

Many people have attempted to put an age to the Earth. Aristotle believed that Earth has existed eternally. Various others attempted to use the bible to extrapolate back from known history which resulted in a relatively recent beginning. In 1654, Archbishop James Usher of Ireland used this theory and estimated the creation of Earth to be 4,004 B.C. (Ticotsky, 2006). A couple of decades later, Nicolas Steno formulated the idea that is now known as “original horizontality” in which layers of…

We know the earth is only about 10,000 because of many reasons. There is not enough mud on the ocean floor. Currently the depth of mud ocean floor worldwide is about 400 meters (hay), but according to evolutionist the ocean began acquiring mud since it has existed around…
