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

Plate tectonic is a scientific theory of Earth Science which basically defines the large scale motions of the atmosphere of the Earth. The Plate Tectonic theory is based on the continental drift concept The theory was first developed in the first decades of 20th century. According to the Plate Tectonic theory‚ the lithosphere breaks up into the tectonic plates. Currently‚ there are seven or eight major plates in the Earth. Generally‚ the lithospheric plates remain on the asthenosphere. All the

“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

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

“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

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

Since the upper mantle acts like a very dense fluid‚ the crustal plates float on top of it. Any change in one part of the crust is offset by a corresponding change in another part of the crust.

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

Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following‚ Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within

Assess the strength of the relationship between tectonic processes and major landforms on the earth’s surface. Tectonic processes have been responsible for the major landforms across the Earth’s surface. These processes are controlled by the convection currents rising from the Earth’s mantle. Firstly‚ one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other‚ pushed apart by huge convection currents
