Convergent boundary

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…

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…

the stationary hot spots has created a large series of volcanos across the island. A previous interpretation showed a sharp bend in the chain about 2200 miles northwest to the island. 2. Hawaiian Island chain is located on a plate boundary? Yes it is located in the boundary of pacific plate. 3. Which of the island is youngest? Hawaii is the youngest of island. 4. Which of the sea mount is the oldest? Loihi is the oldest located sea mount on the Emperor Seamount chain. 5. How did the island and…

while the latest activity took place in the eastern portions of the piedmont. The Liberty Hill is one of a number of these granitoids where we see an early coarse grained facies intruded by a more recent fine grained facies. There is a gradational boundary present between these separate facies. The Liberty Hill has a total of three facies which differ both in minerology and texture. Internal igneous flow features on the granitoid suggest the three-dimensional shape to be a nearly circular…

it cools, spreads and new magma from the bottom, rises to the surface as the cooling magma descends, “Just like a pot boiling on a stove” (Van der Elst). Convection is the cause of the movement of the plates, and there are three different types of boundary movements. Firstly, converging movement, which is a destructive process where the plates collide; secondly, diverging or spreading, where land is created by the plates spreading and finally, transforming movement a process in which no land is…

certain spots of western South America. I believe that this particular formation will continue to form more and more volcanos as time goes by. This would most likely happen because of the subduction boundary going on (South American plate is continental, Nazca Plate is oceanic), and if the Nazca boundary continues to push underneath the South American one, it will cause the plate to liquify, which accordingly would cause eruptions. Because of the eruptions, the volcano would continue…

Rise spread 5 times faster than the Mid-Atlantic ridge. Due its fast spreading, the East Pacific Rise doesn’t have a rift valley instead it possess a smooth volcanic summit with a crack throughout the crest. (Please refer to diagram of Divergent Boundary (Mid-Ocean Ridges)) Do you understand how volcanoes is being produced underwater…

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…

planet. " There are no long, linear volcano chains or any clear subduction zones. The transform plate boundary, causes the plates to slide past one another, which may cause earthquakes or fault lines, which is exactly what is happening. The plates are sliding past one another and earthquakes ar occuring which may lead one to believe that there are plate tectonics on Venus. Diverging plate boundaries occur when plates are moving apart, and new crust is created. Geological features formed,…

Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…
