Chapter One The theory of plate tectonics explains how forces within the planet create landforms. This theory views Earth’s crust as divided into more than a dozen‚ rigid‚ slow-moving plates. Some plates are as large as a quarter of the planet‚ but others are only a few hundred miles across. The plates slowly move across the upper mantle‚ usually less than an inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a few

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

Plate Tectonics: An Essay By: Grace Park Science 9 Mr. Achor 11-22-11 In the early 1900’s‚ scientists began to ask questions about the earth and it’s continents. Why are the same fossils found on opposite sides of the globe? Why do South America and Africa seem to fit together like two pieces of a jigsaw puzzle? Some scientists went to rather extreme measures to explain these strange phenomenons. Others took the time to come up with detailed theories

CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these

1. Compare the age of igneous rock found near the mid-ocean ridge with that of igneous rock found farther away from the ridge. The ages of the igneous rock found near the mid-ocean ridge was younger than the igneous rock found farther away from the ridge. This is because of convection currents. Magma rises because it is less dense. It is forced out of the ridge‚ it spreads apart‚ and when it cools‚ it becomes new seafloor. This is why newer seafloor (igneous rock) is younger when it is closer to
