flooding and the possibility of landslides because of flooding. 4.) The three major types of rocks are sedimentary‚ igneous‚ and metamorphic rocks. 5.) The crust and the upper most part of the mantle combined are what make up the lithosphere. The asthenosphere is made up of the mantle that is located below the upper portion and the core combined. 6.) Without plate tectonics the Earth would be less rigid and more flat. There would be less mountains‚ if any‚ as well as volcanoes. 7.) Cavemen never saw

theory of plate tectonics states that the Earth’s lithosphere is broken up into many different pieces separated by jagged cracks. These are called the tectonic plates. They are in slow‚ constant motion pushed by the convection currents in Earth’s asthenosphere. This theory explains the process of sea floor spreading at mid-ocean ridges‚ and subduction at deep ocean trenches. It was proposed by J. Tuzo Wilson in 1965. He combined the discoveries of Harry Hess and Alfred Wegner to support this theory.

almost draw a straight line to connect all the volcanoes. Moreover‚ the data above is evidence of the presence of subduction zones wherein the collision of two plate boundaries causes the denser plate to sink below the less dense plate into the asthenosphere. This type of tectonic activity promotes the formation of volcanic island arc-trench systems. The arc-trench systems are located in the active margin (an area immediate to plate boundaries).

that most of the world’s major landforms occur and where earthquakes‚ volcanic and mountain building zones are located. The surface of the planet is made up of seven large and several smaller rigid tectonic plates which float on the semi-molton asthenosphere; the movement of these plates is influenced by the convection cells under the lithosphere‚ generated by heat from the center of the Earth. Plates can move towardsor away from eachother or in parallel‚ the type of landform created at the plate boundaries

Plate Tectonics Ever since the beginning on time‚ Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth‚ and possibly of what the Earth may become at a certain point in time‚ has a great influence on understanding all aspects of living things‚ either in the past‚ present‚ or future. The study of Plate

this document to make sure your work is meeting the expected criteria. Plate Tectonics and Earth Movement Watch this short video explaining how some areas where Earth’s plates meet are identified. Then observe how the plates that rest on the asthenosphere are believed to have moved since Earth’s formation. Now‚ write a 500- to 750-word essay about the processes involved in plate tectonics. Be sure to include examples and evidence supporting the concept of plate tectonics. Type your response

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
