Convergent boundary

When you look at a globe of the earth it is easy to think that the earth has always been this way that the continents and the ocean basins have always been where they are now and they will always be. But if you examine the globe closely you may notice something curious. Some of the continents appear as if they have been joined at one time. A good example of this are the coast lines of South America and Africa. When you compare them with just a little bit of adjustment that they match quite…

spectrum when observing a map. The anomaly is the outcome that causes deviation from the “ideal gravity model” (Reference). Sedimentary basins are large low-lying areas that are dependent on lithospheric flexure. They’re formed due to convergent, divergent and transform boundaries, creating room for sediment infill (Reference).…

River levee, north to the Kentucky Bend, and west to New Madrid, Missouri. This fault ultimately aligns the New Madrid Seismic zone, and it is a reverse fault. A reverse fault is when a hanging wall slides up a footwall. This is a type of convergent boundary where two plates compress together. The New Madrid Seismic zone is known historically for a series of earthquakes in 1811 and 1812. The first earthquake occurred in Northeast Arkansas with a magnitude of 7.5. This was on December…

Section 1: Plate tectonics is the the theory that the outer crust of the earth is cut up into a lot of pieces called plate tectonics. The plate tectonics move around in the mantle. The mantle is the rocky middle layer of our earth it lies right above the core. The plates are very much like a shel going around the earth. The evidence of plate tectonics began as simply circumstantial evidence one example is continental drift which is the theory that all the continents used to be one giant…

Mercury:The surface geology of the planet Mercury can be very easily described as - Rocky. Because of this it bears as strong resemblance to the earths moon. This is due the the heavily cratered surface which has been caused by asteroids which has caused these giant craters in the planets surface, leaving pulverized dust and boulders behind. The reason all of the asteroids were able to hit the surface of this planet is because its magnetic field is not strong enough to deflect or slow them down…

the infamous myth of Atlantis. Santorini is volcanic small island group located 200 km southeast of Greece in the southern Aegean Sea composed of five islands (Thira/Thera, Therasia, Aspronisi, Nea Kameni, and Palea Kameni). It lies on the convergent boundary of the African plate and the Eurasian plate (Aegean subplate),…

The primary purpose of this study is to gather perceptions and opinions of veteran assistant principals and veteran counselors on the impact and changes in bullying with the recent surge of technology and technological devices. The assistant principals and counselors will all be gathered from public school districts in Connecticut. Veteran, as defined by having more than 15 years of experience in a school system, were chosen to better understand the changes technology has had on bullying. The…

locations on the blackboard. Leave this on the board for later discussion with the class. Ask if any students have ideas why the earths outer layer is constantly changing. Lesson: (20 minutes) This lesson will teach the student about fault lines and boundaries where two separate tectonic plates meet, and why volcanoes are formed. Begin with a brief introduction of the theory of plate tectonics. Explain to the class that plate…

bordered by the rim of a summit caldera caused by the breakdown of a former and initially much higher arrangement. The height of the main cone has been continually changed by eruptions but was 4,203 feet in 2010. Vesuvius is a stratovolcano at the convergent boundary where the African Plate is being subducted below the Eurasian Plate. Mount Vesuvius is observed as one of the most hazardous volcanoes in the world because of the population of 3,000,000 people living nearby and its violent…

The first piece of evidence that points to a non-traditional formation of the Rocky Mountains is the rock composition of the ranges in this area. The rock composition in these areas is not sedimentary like we would expect to see in the traditional convergent boundrie folding type of orogenic event. But rather, it is composed mostly of basal igneous rock that seems to have inexplicably risen up from deeper portions of the crust (Pendick and Denial, 1997). The second, and most problematic,…
