The following diagram depicts the elements and movement of continental drift. Report the main features and make comparisons where relevant.
Write at least 150 words.
OVERVIEW (paraphrase of the question WITH more details! + most observable features)
The given pictograph shows the five different components of the earth’s crust involved in the process of continental drift, and their relative sizes. Generally observing the diagram, it is noticeable that the two sides, left and right, appear as almost identical mirror images of one another, and the layers depicted become thinner moving towards the earth’s surface.
Deep in the earth’s crust, the Asthenosphere, which contains magma, is thicker than the other layers combined. The Lithosphere, which is situated between the Asthenosphere, and a similarly thick continental crust, thins as it reaches the Mid-Oceanic Ridge. As the continental crust narrows into the ocean, it meets the thinnest layer, the oceanic crust which has an older section towards land and a newer section at the mid oceanic ridge where magma exits the Asthenosphere. As the magma forces itself upward at the Mid Ocean Ridge to the surface, it not only creates the newer crust but also forces adjacent land masses, or continents, to move away from each other.
In summary, it can be noted after observing this diagram that the force of the larger layer is responsible for the creation of newer crust material as well as the movement of the smaller layers.
