Boundary

geodynamic consistency of the tectonic plate movements, and surface signals such as plate reconstruction. To understand plate reconstructions, Michael Gurnis, explains Plate tectonic reconstructions as “ a description of the continuous evolution of plate boundaries and plate interiors covering the Earth’s surface as a function of time.” Gurnis describes this as plates that are constantly moving because they are continuously evolving over…

vents are fissures in the earth’s surface from which geothermally heated water rises. They are normally found near volcanically active areas, usually in clusters above the given body of magma. As learned in class, we know that in places where plate boundaries are moving apart, molten magma rises and erupts to form new oceanic crust. (Harden 7). This new crust forms volcanic mountain ranges known as mid-oceanic ridges. Mid oceanic ridges form in the very deeps of the ocean causing the water…

plate boundaries. Japan is also located where the Pacific plate and the Philippine plate are subducting. This results in the stress building up where the two plates are subducting. How do plates move? Well, plates move when uneven heating in the mantle creates currents. This current is a convection current, and these currents create different types of plate boundaries. Divergent boundaries split apart from each other and form rift valleys. Transform boundaries slide, and convergent boundaries…

Supercritical fluids are related to superfluids through the concept of Cooper pairs. In a conductive material, such as copper, the flow of electrons move towards the largest positive terminal. The reason why copper is a good conductor is because it is able to lose electrons in its outer shell, and become slightly positive. The combination of the electrons repelling each other, and their attraction towards both the slightly positive copper atoms and positive terminal lead to the electrons…

activity, the first underwater volcano observatory is located near the volcano. (www.pmel.noaa.gov) According to www.en.wikipedia.org, the two plates that create the boundary are called the Juan de Fuca plate and the North American Plate. These two plates form a divergent plate boundary. (www.en.wikipedia.org) A divergent plate boundary is created when two plates pull away from each other. When the plates move away from each other, magma is exposed and seeps through the crack. The magma cools…

The topic of this discussion is to explain why Africa and South America are moving apart. The drifting apart of Africa and South America has to do with the theory known as the theory of plate tectonics. Based on this model, the crust the coolest part of the mantle, make up Earth’s strong outer layer, known as the lithosphere. Right beneath the lithosphere is the asthenosphere, the hottest part of the mantle. Rocks at this depth are very near the melting temperature, and respond to forces by…

the north side remaining more shallow and the south side having a wider range, but again with a lot fewer earthquakes. The middle of the plate, in the sea, there are almost no earthquakes at all. It isn’t unusual to have earthquakes along plate boundaries, as the plates aren’t the smoothest things in the world. The plates could catch or get stuck on each other until the pressure building up becomes too much and one buckles, falling or is pushed up suddenly against the other, creating an…

The location I chose for this assignment is my home county, San Diego. San Diego is known for having the best weather in the United States, which it can attribute to its geology. San Diego is also well known for consistent droughts; however, its current unique geography is a result of ancient rivers and seas depositing Cretaceous and Tertiary sedimentary rocks. As a result of these ancient rivers, “San Diego County can be divided between three distinct geomorphic regions: the Coastal Plain…

two moved plates slip past one another. The earthquakes usually happen in the convergent boundaries, divergent boundaries and transform boundaries. In the three kinds of boundaries, the convergent boundary often produces the largest magnitude earthquakes. Because when the two plates collide strongly in the convergent boundary, the extreme pressure and the great friction will appear. So the convergent boundary is more likely to have a large magnitude earthquake. For example, 1960 Valdivia…

karen Plate Tectonics There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth…
