I wake up to my cell phone ringing. I look at the caller ID it’s my aunt. I think to myself why is she calling at 6:00 am in the morning. I pick up the phone and hear she yell into the phone. “Have you seen what happen to the oceans!” “No, I just woke up what happened?” I replied. “Some strange force sucked up all the water out of the oceans now there is just deserts now!” My aunt yelled again. “What that can’t be right are you just pulling my leg?” I go to my computer and log in and right there in big red letters stretch across the screen ALL THE OCEANS HAVE DRIED UP! I stare at the words on the screen for a good minute not registering the meaning behind the words then I hear my aunt again. “Hey, you still there? I want you to come to …show more content…
I ask my tour guide how seamounts are created and he replied with “Seamounts are underwater mountains that are raised hundreds or thousands of feet from the seafloor. They are created by tectonic plates. Plates that move away from each other then magma when the trenches between the plates are far enough and reach close enough to the core to have magma fills in the new gap and then the magma rises back up and creates the surface of the seamount. Seamounts are like underwater …show more content…
We all keep walking after seeing the Abyssal plain for a little bit then walked over this very long bridge that someone manages to set out earlier for people walking the ocean floor. Two days later our group comes across the Mid-Atlantic Ridge it is about 10,000 miles long splitting North American plate and Eurasian plate away from each other. It’s between a series of flat abyssal plains. The Mid-Atlantic Ridge is located on two tectonic plates that form the floor of the Atlantic Ocean. Apart from the tectonic plates spreading, the Mid-Atlantic Ridge is also the site of volcanic activity and earthquakes. A day later my tour guide stumbles onto the Azores plateau which is an area of thickened oceanic crust and is thought to be formed from the Azores hotspot. The oceanic plateaus are created by magma trenches or plumes. 28°N and 29°W. A day later my group and I finally made it to Portugal Spain. And we all received are 250,000 dollars for participating in the walk. I learned a lot from this walk from New York City to Portugal. From how seamounts were made to actually use some information my 6-grade teacher said. My adventure of the 3,000-mile walk will be something I never
Experiences of journeys provide insights into the lives of individuals and the world around them
Evaluating the Evidence for Continental Drift There are several pieces of evidence certifying the existence of continental drift. They include mid oceanic ridges, fitting of continents, similarities of fossils on different continents and rock matches. The mid-oceanic ridges rise 3000 meters from the ocean floor and are more than 2000 kilometres wide surpassing the Himalayas in size. The mapping of the seafloor also revealed that these huge underwater mountain ranges have a deep trench, which bisects the length of the ridges, and in places is more than 2000 meters deep. Research into the heat flow from the ocean floor during the early 1960s revealed that the greatest heat flow was centred at the crests of these mid-oceanic ridges.
According to Levin, “This subduction created batholiths, compressional structures, volcanism, and metamorphism that accompanied Mesozoic and Cenozoic orogenies.” The dense oceanic crust was subducting beneath the continental crust more quickly than it was being created at the mid-ocean spreading ridge. The oceanic crust was part of the Farallon plate, which has now almost completely disappeared because it was consumed by the North American plate (Levin).
It was a warm rainy June night the humidity was high which made it even harder to breathe on the crammed boat. My family was asleep on the constantly rocking boat suddenly the boat shook, but my family was still fast asleep. I couldn’t seem to fall asleep so I got up and stepped out on the cold wet steel boats upper deck to get some air. When I got outside I realized that it was pouring bucket sized rain. I saw increasingly large waves crash furiously against the lower deck. Hard water droplets pelted my face, I could taste the salt water in my mouth from the spray of the ocean. Suddenly A massive wave slammed hard against the ship and almost swallowed the boat. Wind gusts started kicking up. I held onto the rail grasping it as if it were my prized possession. Suddenly I was blown
Ever since the idea of Atlantis being a city explorers and scientists have looked for Atlantis. One idea is that the Mid-Atlantic Ridge was caused by the sinking of Atlantis. But this is disproved because if Atlantis did sink in the Atlantic Ocean then it would not have created a ridge or ridge like area. The Mid-Atlantic Ridge is caused by Divergent tectonic plates in the ocean which creates the ridge. The sinking of Atlantis could not have done this. Not only is this impossible but the descriptions given by Plato would also be off. The Mid-Atlantic ridge is a mountain like area going from north to south for a few thousands of miles; Plato described Atlantis a circular island that was maybe one hundred miles in diameter. Therefore this theory does not work.
Tuzo Wilson hypothesized in 1963 that the production of the volcanic mounds of land were formed by Hotspots of magma that found its way through the oceanic crust. To account for the size and number of islands within the Hawaiian chain of islands (called the Hawaiian Ridge-Emperor Seamounts chain), it was believed that the Hotspot was stationary, while the Pacific plate moved at a rate of about 3 centimeters a year over it. When the hotspot produced magma, the plate (i.e. the crust) was simply in a new place, rendering one volcano extinct, and creating a new active one. The islands as they stand today are thought to have been made around 70 million years ago (USGS). What makes the islands of Hawaii so unique is their complete reliance on these magma filled Hotspots, making nearly the entire mountain range built entirely by volcanic activity; each island being the top of an enormous volcanic
Primary coasts are divided into two categories: submergent and emergent coasts. Submergent coastlines result from a general sea-level rise and crustal subsidence. Most of the eastern United States has submergent coastlines. One example is the Chesapeake Bay. Emergent coastlines result from the land being lifted, either by tectonic activity or rebound from the weight of heavy glaciers, which exposes the former sea bottom bit by bit forming continuously new shoreline.
Basalt forms due to the partial melting of the layer of the mantle called the asthenosphere. The asthenosphere is the plastic zone of the mantle beneath the rigid lithosphere. Mantle plumes coming from the mesosphere can cause the asthenosphere to melt with heat or even if pressure decreases, which is called decompression melting (Richard 2011). The magma that forms from this melting is mafic magma that solidifies once it reaches the earth’s surface and cools quickly. The above process mainly occurs mainly during intraplate igneous activity which is the main explanation for volcanic activity that occurs a long distance away from a plate boundary. If the tectonic plate above the mantle plume is moving it can create a string of volcanic activity such as in Hawaii. See Fig 2.
When I walked inside the front door something didn’t seem right. The feeling of sorrow overwhelmed the house. It was so thick I could literally feel it in the air. Everyone was motionless. They were sulking;I was befuddled. The most energetic people in the world, doing absolutely nothing. I repeatedly asked them what was wrong. After an hour or so, my dad pulled me aside. He said that my Aunt Feli had passed away last night. My mind went for a loop, I was so confused. I thought that he was joking, so I replied “You’re lying, don’t mess with me like that.” and punched his shoulder softly while I chuckled. My dad quickly started tearing up and said, “There...
Rocks are hard but in time they can bend or fold producing folded mountains. The Alps formed as the Eurasian plate pushed against the African plate. Other examples of folded mountains are the Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are formed when one plate pushes or pulls away from another plate. On the Earth, hot currents of magma or molten rock may well up and crack the weakened crust above.
I decided that this time I would have to go much farther, to the United States. I cut my hair short, wore men's clothes, and came up with the identity Frank Thompson, to get a job. I fled with only five dollars and hope for the future. I walked more than 450 miles, God lead me the whole way. I walked all the way to Flint, Michigan where I became a bible salesman. Even though I was supporting myself I still felt my purpose was to do something bigger. This ambition stayed with me my entire life. This helped me do great things for a cause I believed
The Creature That Opened My Eyes Sympathy, anger, hate, and empathy, these are just a few of the emotions that came over me while getting to know and trying to understand the creature created by victor frankenstein in Mary Shelley’s Frankenstein. For the first time I became completely enthralled in a novel and learned to appreciate literature not only for the great stories they tell but also for the affect it could have on someones life as cliché as that might sound, if that weren’t enough it also gave me a greater appreciation and understanding of the idiom “never judge a book by its cover.” As a pimply faced, insecure, loner, and at most times self absorbed sophomore in high school I was never one to put anytime or focus when it came time
I awoke the next morning to the sound of thunder. I rolled groggily out of bed, rubbing my eyes. I put on my glasses and opened my window blinds. What I saw was not our new immaculate backyard, but a wasteland of water and mud. I stood there for a few seconds, taking in the whole scene. At first, I thought I was still asleep. There was no way that my backyard, the backyard I where I was supposed to have my party, was this disaster area. In my sleep-induced thoughts, I suspected that I had just dreamed that my birthday was today; maybe it was all in my head and my birthday really wasn't until tomorrow. Then my mother came into my room and said, "Justin, we have a problem. It's raining outside, and there are only a few hours till your party starts."
A mountain is the most basic result of two plates colliding. A mountain is formed when two continental plates collide, the plates crunch and fold the rock at the boundary, lifting it up and forming mountains and mountain ranges. According to the science textbook on page 206 lines 19-22 the text states “Two plates carrying continental crust can also collide. Then, neither piece of crust is dense enough to sink far into the mantle. Instead, the collision squeezes the crust into high mountain ranges.” The second possible landform that is caused by a convergent boundary is a deep ocean trench. A deep ocean trench is an underwater subduction zone involving two oceanic plates, or a continental and oceanic plate. A subduction zone is where two plates collide and the older, denser, and colder tectonic plate goes under (or subducts to) the newer, less dense, warmer tectonic plate. The plate which had more time to cool subducts under the hotter plate because in a colder substance the molecules are closer together which makes the plates substance more dense which causes the plate to sink. Whereas in a warmer substance, the molecules that make up the object are farther apart and are
The concurrent convective circulations in the mantle leads to some segments of the mantle moving on top of the outer core which is very hot and molten in nature. This kind of movement in different segments occurs as tectonic plates. These tectonic plates are basically seven on the earth surface as major ones, although, several small ones exist also. The plates motions are characterized by varying velocities, this variance results to sub sequential collision of two plates (leading to formation of a mountain in a convergent boundary), drift of two plates (leading to formation of rifts in a divergent boundary), or parallel movement in a transform boundary(Webcache 3).
