Convergent validity

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 collide.Eventually, the stress builds up and once it’s released it sends out seismic waves being sent out which produces an earthquake. Once this earthquake has hit Japan a tsunami follows. Sometimes an earthquake can even make an…

New crust is generated as plates pull away from each other and can either cause sea floor spreading or new land to be created. An example of a continental rift valley is the Eastern African Rift Valley which is being formed as the Eastern African plate is moving away from the main Africa plate in a north-easterly direction. Plates move apart due to convection currents in the lithosphere. As the crusts move away from each other the crust thins, tension in the lithosphere causes the plate to…

It is defined as a movement in the oceans that has a direction and is continuous. These abiotic features of the environment are created by the average or mean flow of the seawater, winds, Coriolis Effect, salinity and temperature difference, cabbeling and breaking waves. Coriolis Effect is the result of the rotating Earth. The rotating Earth changes the straight line path of the current and winds as they travel. Thus, the currents due to this in the Northern part move to the right side whereas…

as for those who attempt to achieve their life long goal of climbing the tallest mountain on the face of the Earth. Despite the extremely beautiful views that this mountain range provides, it poses a tremendous threat to those who live near this convergent plate boundary. In Susan Hough’s article titled Kashmir Valley Megaearthquakes, she discusses previous earthquakes that have occurred in the Kashmir Valley, and predicts an upcoming mega quake that will someday occur in this region. By using…

CHAPTER ONE 1. INTRODUCTION 1.1. BACKGROUND AND JUSTIFICATION Pan African Orogen (PAO) was formerly introduced by Kennedy (1964) to designate the peak of a wide spread orogenic thermo-tectonic episode characterized by intense period of reactivation and crustal formation. The term Pan African Orogen was used to describe the structural differentiation of Africa into cratons and mobile belts during the Neoproterozoic to earliest Paleozoic time (Kennedy, 1964). However, Kröner (1984) reformulate…

Volcanic Application Assignment 1. Which Plate contains the Hawaiian Island-Emperor seamount chain? The Pacific plate contains the Hawaiian Island-Emperor seamount chain. This mountain range is under water mountain range, it reaches above the sea level in Hawaii. Composed a rigid mountain range it is situated in the northwest of Kure and Emperor Seamount. Starched from the northwest to southwest beneath the Pacific Ocean it consists of many seamounts, shallow banks and reefs along the line. More…

The Liberty Hill pluton of South Carolina is one of twenty-four known granitoid bodies along the southern Appalachian Piedmont which possess the properties of a supergroup as described by Pitcher. The country rocks surrounding the plutons are at least mid-Paleozoic in age. Liberty Hill lies within country rocks of the Carolina Slate belt which consists of “primarily intermediate to felsic pyroclastic debris and hypabyssal intrusive bodies.” (Speer et al. 1980). The isotopic ages of…

crust when 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…

mainly magnesium and iron. Oceanic rock is also 7-10 kilometres thick. It has a density of 3 grams per centimetre cubed. 9. Define the terms subduction, mid-ocean ridge, and ocean trench and island arc. Subduction is when two tectonic plate’s convergent boundaries come crashing together resulting in one going below the other. This results in the bottom plate to sink into the mantle. Mid-ocean ridge is an underwater mountain ridge that forms when convection currents causes magma to rise where…

Question: Describe in detail the three theories that were the predecessors to plate tectonic theory. Provide evidence of how features of the surface support the current, theory of plate tectonics describing the ways the tectonic plates interact and the result of their interactions. The Continental Drift Theory The Continental Drift can help the surface support the current by plowing through ocean basins. It also did not include seafloor spreading or subduction. So, that did not cause an…
