Plate Tectonics Movement
The Movement of Plate Tectonics Many scientists have done research on all continents being combined into one. This super continent is known as Pangea. Pangea existed 175 million years ago. But as time went on the continents slowly drifted apart. Underneath the earth are plate tectonics, and when the earth drifts apart the plate tectonics move and cause many things to happen. Many of our landforms were created because of this. Three examples are volcanos, earthquakes, and mountains.
To begin, volcanos are a great example of landforms being created by the movement of plate tectonics. When the plate tectonics move, it causes pressure inside the earth that creates volcanoes. “The pressure inside the earth forces magma up through a weak point
Nt1310 Unit 1 Assignment
624 Words | 3 PagesRocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.
Catalina Shist Case Study
899 Words | 4 Pages1. What is subduction and how did it plus faulting lead to the formation of Catalina’s island? Blueschist, greenschist, and amphibolite rocks are typically found in this order from top to bottom. Amphibolite is found at more intense pressures and temperatures than schists are found due to these metamorphic rocks being made from sediments that get subducted back down into the mantle. The unique Catalina Schist was formed when these layers of rock in the Farallon plate became subducted underneath the North American plate and eventually becoming “stuck.”
Explain Why Did The Alaskan Way Viaduct Collapse
464 Words | 2 PagesThe asthenosphere is making convection currents. Since the convection currents are always moving it causes the asthenosphere to move and bend because it is ductile. When the asthenosphere moves which is under the tectonic plates it will cause an earthquake or more specifically the Alaskan Way
Ap Environmental Science Chapter 14 Summary
442 Words | 2 Pages- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock
Factors That Helped The Formation Of Connecticut River Valley
499 Words | 2 PagesThe Connecticut river valley was also formed from many rifts and faults that had developed. A rift valley is a region of lowland that forms where tectonic plates move apart, which is how the river valley was formed. On the other hand, the plate tectonics also formed the Appalachian mountains. The Appalachian mountains were formed by convergent boundaries, which is when two plates collide. The
St Helens Research Paper
1299 Words | 6 PagesThis volcanism has included such notable eruptions as Mount Mazama (Crater Lake) about 7,500 years ago, Mount Meager about 2,350 years ago, and Mount St. Helens in 1980. Major cities affected by a disturbance in this subduction zone would include Vancouver and Victoria, British Columbia; Seattle, Washington; and Portland, Oregon. The two tectonic plates involved in the subduction process at the convergent fault line are the Juan de Fuca plate and the North American plate. The Juan De Fuca plate being the denser oceanic plate is being subducted under the continental North American plate. Although the fault line is on the coast of the Northern American plate tectonic activity is also heavily present inland, evidence of this is the cascade volcanic arc formed by the tectonic movements at the fault
Glass House Mountains Research Paper
833 Words | 4 PagesWell, there are many theories. There is the aboriginal legend, the Bible theory and then the scientist theory. All of which lead to the same conclusion, however, the processes of getting to the conclusion are completely different. Scientist's believe that 30-22 million years ago the continent was thought to be moving over a 'hot-spot' in the earths mantle beneath the crust.
Mount Shasta Research Paper
910 Words | 4 Pages#31 Zongpei Yang Introduction: Volcanoes come in different sizes and shapes. There is a different kind of volcanoes in the world in different areas for example the desert or just normal grasslands. What I think of volcanoes is lava flowing from a mountain or that’s what I think. The volcano that I am doing is named Mount Shasta the fifth tallest mountain in the world!
The Hawaiian Island Chain
889 Words | 4 PagesPlate tectonics is a theory that Earth’s crust is composed of nearly a dozen plates, which have shifted around the surface of the Earth over time. This theory provides a reasonable explanation for how mountains formed, and why there are earthquakes and volcanoes. Additionally, this
The Stonehenge Theory
792 Words | 4 PagesIn this theory, the majority of the heavy moving was completed by the glaciers instead of humans. (Cohen ) ¨ The globe is dotted with giant rocks known as glacial erratics that were carried over long distances by moving ice floes.¨ (Cohen ) Furthermore, Dr. Brian John, an Archaeologist, had traced pieces of debris back to half a million years ago which would go along with the glacier movement.

North Carolina Earthquake Research Paper
321 Words | 2 PagesHow do earthquakes form? Earth quakes form when two earth blocks slide past each other. When they slip past each other it is called a fault. Earth quakes
Costa Rica Volcanoes
837 Words | 4 PagesThese two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
The Rings Of Fire: Tectonic Plate Boundaries Of Tsunami
300 Words | 2 PagesThey can float in water because they are made out of granite. Granite is a very lightweight material unlike basaltic rock which is a very dense and heavy material. Tectonic plate boundaries are places where two or more tectonic plates are moving towards or away from each other. The Rings of Fire is a huge tectonic plate boundary that is located close to the coasts in Pacific Ocean. Over 80 percent of all tsunamis happen there.
Cause And Effect Essay On Earthquakes
1247 Words | 5 PagesEarthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
