Plate Tectonics Chart Amanda Wright GLG 150 February 24‚ 2013 Karen Hansen Plate Tectonics Chart 1) How does the motion of the tectonic plates affect the climate? Climate can be affected by many things. One of the biggest affects may be the motion of the tectonic plates. The Earths plates have been in motion approximately since its beginnings or shortly after‚ continuously causing climate to change. The Earth’s movement of plates as well as the apparent polar wandering can both play a role

Africa to the Mid-Atlantic Ridge is approximately 2‚400 km‚ calculate how long ago that point in Africa was at or near the Mid-Atlantic Ridge. That point in Africa was at or near the Mid-Atlantic Ridge 192 million years ago. I got this answer because I know that the movement of the seafloor is about 1.25 cm per year. I converted 2‚400 km in to 240‚000‚000 cm. Then I divided 240‚000‚000 by 1.25‚ and I got 192 million years. 3. How could you use this method to reconstruct Pangaea? I could use this

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

The Movement of Plate Tectonics Brandon Womac Plate tectonics have played a major role in the history of the Earth. All seven continents are where they are today due to the movement of plate tectonics. These seven continents were one big supercontinent called “Pangea” about 200 million years ago before breaking apart. The three different types of plate boundaries are convergent‚ divergent‚ and transform. These plate boundaries form due to the earth’s outer shell called the lithosphere having multiple

“EVALUATE HOW PLATE TECTONICS THEORY HELPS OUR UNDERSTANDING OF THE DISTRIBUTON OF SEISMIC AND VOLCANIC EVENTS” In this essay I am going to look in detail at plate tectonic theory and how it can be used to explain seismic and volcanic events worldwide. However‚ I will also look at other potential causes of these events‚ and some evidence that does not follow the theory that all these events are caused by plate boundaries. I am going to look at a range of case studies from differing scales

How does the plate tectonics theory help explain the existence of fossilized marine life in rocks atop the Ural Mountains? Be sure to include a description of the specific process(es).’ Continental Collisions would be a possibility as this would birth mountain building. It is a theory that Europe and Asia collided millions of years ago. Marine life would have existed in the ocean basin between the land masses. As the continents approached‚ waters would recede from between them through subduction

Plate Tectonics Plate tectonics is the science and study of causes and relative motions of earth’s lithosphere plates. This theory proposes that earth’s outer layer is made up of plates which have moved throughout earth’s history. It is the scientific theory that attempts to explain the movements of the Earth’s lithosphere that have formed the landscape features seen across the world today. The primary natural hazards facing the islands of the Caribbean are earthquakes and hurricanes. Some of the

Activity No. 2 Simulating Movement of Tectonic Plates Problem: How do tectonic plates move? What you need: -4 pieces of colored modeling clay -cardboard -newspaper What to do: 1.Flatten two pieces of modeling clay on the newspaper. 2.Cut the center of the clay strips and insert a cardboard on the part of the clay that was cut. 3.Push both ends of the clay strips.Observed what is formed. 4.Repeat step one in the other two pieces of modeling clay. 5.Slowly pull both

Powerpoint Templates Page 1 The Earth’s Plate Tectonics James Hutton was the first scientist to address the Earth was millions of years old‚ as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism‚ and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of the first to recognize and have an understanding of how the Earth works which required data and information

“Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events” (40 marks) The theory of plate tectonics was first introduced by Alfred Wegener in 1912. He observed the continents an could see they interlock like a jig saw puzzle‚ for example the West African Coastline fits snugly into the South American coastline‚ he suggested that at one point in time there was only one giant continent called “Pangea”. Later evidence was found that proved this theory
