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

Have you ever wondered 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

book explaining his theory that the continental landmasses‚ far from being immovable‚ were drifting across the Earth. He called this movement continental drift. Wegener noticed that the coasts of western Africa and eastern South America looked like the edges of interlocking pieces of a jigsaw puzzle. He was not the first to notice this‚ but he was the first to formally present evidence suggesting that the two continents had once been connected. Wegener was convinced that the two continents

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

How does the theory of plate tectonics help to explain the world distribution of earthquake and volcanic zones? The Earth’s crust is made up of seven major plates and several smaller plates. These plates drift on top of the mantle. When two plates meet‚ they can either be constructive‚ destructive or conservative. At a conservative plate margin‚ one plate moves past another. As the plates are not smooth‚ great amounts of tension build up and earthquakes are made when the tension is released

Why is the Pacific Ocean unsafe? In 2011‚ Japan suffered a major travesty due to the 9.0 magnitude earthquake‚ and tsunami that followed soon after. However‚ during that earthquake and tsunami‚ a nuclear power plant known as Fukushima Daichii was hit‚ and exposed to the community. Being exposed to a nuclear power plant is extremely harmful because of the symptoms that may occur from it‚ due to radiation. According to the 2013 edition of the Encyclopedia‚ radiation is a‚ “flow of atomic and subatomic

INTRODUCTION: The Ring of fire (figure 1) is a horse shoe shaped fault line. This fault line is prone to Earth quakes and volcanic eruptions. The ring of fire Is home to 452 volcanoes and 75% of the worlds dormant and active volcanoes live on the Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very slowly

To answer the following question: Relate the generation of all three rock types (igneous‚ sedimentary‚ and metamorphic) to plate tectonics. I will start first‚ with igneous rocks and how does it relate to plate tectonics. Second‚ with sedimentary rocks and progressively keep on answering how all three types of rocks relate to plate tectonics. Will be giving as much information I learned from class. To assure‚ answer is fully answered. The igneous process begins when magma forms by melting at depth

processes were plate tectonics‚ glaciation‚ and weathering & erosion. One example of plate tectonics in CT is the Connecticut River Valley. The Connecticut River Valley was also formed by glaciation but first came the plate tectonics. When the plates divided it created a rift valley‚ (When the land on two sides rises but the middle land lowers or stays the same.) rift valleys can be formed by earthquakes and some other natural forces as well. This is only one example of plate tectonics. Another example
