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

Would the world be the same if there weren’t plate tectonics? The answer is no‚ because that is how the oceans‚ land‚ and many more things were created. There would be no rocks or plate boundaries. Every living thing on earth would have to adapt to these types of things‚ if there even was living things on earth. The different types of rocks like igneous‚ sedimentary‚ and metamorphic have to go through a process to become that type of rock. Igneous is formed when magma is cooled and

Landforms are the physical features of the earth. They are described with particular attention to the contours of the land slope‚ elevation and morphology as well as the context in which the landform resides. For instance‚ landforms may be categorized based on how they are formed (such as by erosion) or what surrounds them (such as surrounded by water or mountains). Landforms are distinct from the biota (plant and animal life) that inhabit the ecosystems contained within the landform. Scale -

The Impact Of Plate Tectonics on the Caribbean * The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. * Volcanic activity in the Caribbean itself‚ as distinct from Central America‚ is largely limited to the eastern Caribbean. Here‚ the Caribbean plate‚ moving approximately west to east‚ meets the North American plate‚ which is moving approximately east to west. This creates what is known as a seductions

Will the Atlantic Ocean ever be bigger than the Pacific Ocean? The earth first started off as one huge continent called Pangea. Pangea was surrounded by one giant body of water. Over the course of millions and millions of years‚ Pangea began to break off and separate. After millions of years of movement‚ that is why the earth has the formation that it currently has‚ with seven large continents. With an area of 41‚105‚000 square miles‚ the Atlantic Ocean is currently just a little over half the

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

Plate Tectonics Plate Tectonics The theory of plate tectonics was developed in the 1960’s and states that the earth is broken into a number of shifting plates. Plate tectonics also provides geology with a comprehensive theory of how the earth’s crust moves. In this essay I will explain the different types of plate movements‚ how the plates move and how this movement affects earthquakes and volcanoes. To begin‚ there are three different types of plate movement; divergent boundaries‚ convergent
