Plate Tectonics Essay

Something beautiful can also be dangerous, as like the darkness can have phenomenal results. Volcanoes are one example of nature’s beauty, they can be fascinating, exciting, magnificent, but they can also be catastrophic. Their hazard eruptions put many lives at risk, destroying properties, places, and can disrupt air quality. The list of volcanoes is huge, there are three groups of them, dormant, extinct and active volcanoes. From the latter group there are about 500 in the entire world. Although

Have you ever wondered what causes things to happen? Ask the ancient greeks and they will tell you about the hundreds of gods that control our world. Ancient greeks believed that there are gods for everything in the world. Take Poseidon for example, the god of sea, earthquakes, and storms. Poseidon is the god that causes storms, waves, and even hurricanes. Let's look at some family, history, physical appearance, celebrations, and some amazing facts about Poseidon. Poseidon had a huge and interesting

The Precambrian is the name given for the first super eon of Earth’s history (Mary Bagley, Accessed: 20th Aug 2016). This era itself has been recorded to be about seven-eighths of the entire earth’s history. This era stretches across from 4 Billion years ago up until only 543 Million years ago (Mya) which shows how large and substantial this era was. Precambrian itself refers to the time before the Cambrian period. It also refers to the entire period of time before the formation of the oldest

your body moving it was the Earth that was shaking you, an earthquake occured. Earthquakes happen when the underground continental plates move. Earthquakes can affect the Earth, people, and property. To begin with, when an earthquake happens something on Earth is most likely to change. It says in Source 1: “If you Traveled to Gondwana…”, when two continental plates meet volcanoes erupt and mountains can form. When a volcano erupts the lava destroys everything in its path and completely destroys

Mount St Helens Volcano 1980 The Eruption Pre May 18, 1980 Mount St. Helens is an active volcano in the Cascade Range. It is situated in southwestern Washington about 70 km northeast of Portland, Oregon (see Figure 1). Prior to 1980, the last time it erupted is believed to have been in 1857. The first indications of renewed Figure 1: Mount St. Helens location activity in 1980 were observed in the middle of March when earthquakes were detected beneath the volcano. There were many

Review of Subduction Slabs Study: From a variety of observations Prepared by: Yang Yang September 25, 2014 Abstract Subduction zones are sites of convective downwelling of Earth’s lithosphere, which provides the dominate force of the driving force for mantle convection. It is through subducted slabs that oceanic crust and sediments, including volatile compounds are recycled back into mantle. Studying subduction slab is one of the most important parts of studying lithosphere dynamics. There have

as much as 6.0 and greater effects that ended up acting on the land in the following days and months even after the quake had subsided. The tsunami that accompanied the earthquake originated from a fault along the convergent plate boundary at the section where the Pacific plate joins with the west beneath Japan. The subduction zone was very active seismically at the time of the occurrence of the earthquake. Thus based on my understanding of earthquakes, the March 11 disaster was among the strongest

How did the Oceans form? Around 4.4 billion years ago Earth was covered in Lava and rock. There are many theories about how water came to Earth to form what we now call oceans, but scientist has narrowed it down to the two most believable theories. The first theory is the inside-out theory, which proposes that the Earth formed with trace amounts of water structurally bonded to the minerals in the mantle. This water makes its way to the Earth’s surface through volcanic processes. The second theory

It’s 5:15 AM, and the streets are quiet. By 5:30, the streets are torn apart, and rubble is strewn everywhere. What happened in those fifteen minutes was the San Fransisco earthquake. When you look at “Comprehending the Calamity” by Emma Burke and Laurence Yep’s Dragonwings, you can truly imagine the extent of the damage and fear, even though Burke’s purpose is to inform, while Yep’s is to entertain. Emma Burke’s point of view of the earthquake in “Comprehending the Calamity” was that it was violent

Both the Tuscarora and Morrison formations have similarities. At the same time, they both are composed of unique materials that is what set them apart and thus the reason I say they have differences. Obvious differences will include that the Tuscarora is known as an eastern sandstone, while the Morrison is a western sandstone. More obscured differences can be like what ages they are in. The Tuscarora formation is in the Silurian age, located in Pennsylvania, mostly composed of quartzite, and is
