Plate Tectonics & Marine Resources The ocean is one of the worlds greatest natural resources. It provides the Earth’s population with numerous amounts of resources that have value and others that provide pure enjoyment. Transportation is one of the major uses of the ocean‚ along with recreational activities‚ and inspiration. As for resources extracted from the ocean that provide the economy with value‚ three of the main include oil‚ minerals‚ and food. Oil or gas are the top resources extracted

how you could compare continental drift‚ sea-floor spreading‚ and plate tectonics? Well there are actually plenty of ways to compare these three topics in earth science. You could compare these topics in similarities; continental drift and plate tectonics both start on the same basis of idea‚ that Earth’s lithosphere is made up of tectonic plates. You could also state some differences‚ such as continental drift occurs on all plate types‚ but sea-floor spreading only takes place on oceanic crust‚

(centered in Nevada this area is about 1500 kilometers wide and runs about 4000 kilometers North/South). Continental crust is thickest beneath mountain ranges and extends into the mantle. Plate Tectonics * The Earth’s surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). * These plates are in constant motion travelling at a few centimetres per year. * The ocean floors are

Types of volcanism associated with plate margins There are two types of plate margin. When there is a boundary between two diverging tectonic plates‚ such as between the North American and Eurasian plates‚ it is known as a constructive plate margin. This is because it recognises the importance of magma rising up from the mantle to create new crustal rock. The boundary between two converging plates is known as a destructive plate margin‚ as it is responsible for more violent seismic activity‚ volcanoes

CARIBBEAN PLATE The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. Roughly 3.2 million square kilometers (1.2 million square miles) in area‚ the Caribbean Plate borders the North American Plate‚ the South American Plate‚ the Nazca Plate and the Cocos Plate. These borders are regions of intense seismic activity‚ including frequent earthquakes‚ occasional tsunamis‚ and volcanic eruptions. The Caribbean Plate is a

Aside from being one of the basics for survival‚ gatherings are also made perfect by food preparation and stress is now often associated with food.

Discuss the evidence for tectonic plate movement There has been a variety of different evidence for tectonic plate movement but the main evidence was Wegener’s theory which was based on a variety of different evidence from several sciences. Alfred Lothar Weneger was a German polar researcher‚ geophysicist and meteorologist‚ he first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. In 1912‚ he proposed his explanation – the

one another. These pieces slowly assumed their present positions as the continents. PLATE TECTONIC THEORY Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. There are seven or eight major plates and many minor plates. Where plates meet‚ their relative motion determines the type of boundary: convergent‚ divergent‚ or transform

Constructive Plate Margin * This is where two plates move apart be it any combination of crust type either sial or sima. At a sima and sima divergence such as the Eurasian Plate and the North American Plate‚ both crusts diverge leaving magma to rise up. This with aid from the cool ocean water solidifies and creates gentle sloping volcanos with basic basaltic lava with low viscosity. The type of volcanoes found at these margins are shield and fissure volcanoes. At this specific plate margin‚ at

the topographical features at divergent and convergent plate margins. Subject: Earth Environments 1: Geomorphology and Soils Course Code: GEOG 1231 Divergent and convergent plate margins are both studied in plate tectonics; which is the study of the plates that makeup the lithosphere‚ their movements and how these movements has influenced changes in the surface’s topography (Strahler‚ 2011‚ 389). The driving force that causes these plate movements is the gradual movement of the semi-molten rock
