roles do plate tectonics play in the geomorphology of Pacific Islands? The earth’s crust is made out of plate tectonics. Each plate has a defined boundary and direction it moves. The plates in Earth’s crust perform two actions; they submerge under each other or they spread out. The Pacific Plate is the largest plate and it borders around many plates. The Pacific Plate moves northwest. New crust is formed from magma outpours‚ which are a result of the zones spreading. The tectonic plates created the

crust that creates seismic waves. CAUSE OF EARTHQUAKE Earthquakes are caused by the movement of the earth’s tectonic plates. Earthquakes occur where the earth’s plates meet along plate boundaries (see plate tectonics page for more information on this).For example as two plates move towards each other‚ one can be pushed down under the other one into the mantle. If this plate gets stuck it causes a lot of pressure on surrounding rocks. When this pressure is released it produces shock waves. These

the risk they pose differs around the world. One factor that heavily influences how hazardous a volcano is‚ is the plate boundary that it lies on. Subductive plate boundaries tend to produce much more violent eruptions than conservative or constructive margins. Subductive boundaries occur where two plates (one continental and one oceanic) are moving toward each other. The denser plate‚ the oceanic‚ is forced underneath the continental. As it subducts into the asthenosphere‚ it begins to turn back

with the African plate becoming part of a supercontinent. During one of earlier collisions‚ tremendous heat and pressure were generated. This changed the Smoky sedimentary rocks. For example‚ sandstone became recrystallized into quartzite and shale became slate. The last great episode of the mountain building uplifted the entire Appalachian mountain chain from Newfoundland‚ Canada to Alabama. The mountains then were much higher than they are today. As the African tectonic plate gradually pushed

Drift Abstract The Earth is formed by plate tectonics continuously shifting causing a continental drift. This theory is more accepted than when it was originally published due to better technology providing better research and evidence. This paper discusses a little on both the plate tectonics and the continental drift as well as how the scientific method helped understand this process better. key words: Continental Drift‚ Scientific Theory‚ Plate tectonics In 1915‚ a scientist by the

Geology Study Guide Chapter 1 Themes of Textbook The Earth is a unique‚ evolving system. Within the Earth System‚ chemical elements pass in cycles between different types of rock and sea‚ rock‚ and air. Plate Tectonics explains many Earth processes. Earth has a core‚ mantle‚ and crust.

where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth’s crust in the interiors of plates‚ e.g.‚ in
