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

Litosphere: the rigid outer part of the earth‚ consisting of the crust and upper mantle. d. Asthenosphere: the upper layer of the earth’s mantle‚ below the lithosphere‚ in which there is relatively low resistance to plastic flow and convection is thought to occur. e.

volcanoes are created and new rocks are formed. Plate tectonics allow scientists to know about the earth’s centre. The oceanic plate slides under the continental plate because it is heavier. Once it goes under the continental plate it melts into the asthenosphere. The Richter scale is a scale that scientists use to measure the magnitude of an earthquake. It can tell us how much the earth’s crust has moved (how hard; effecting the surface). A shift along a fault on the continental crust could also cause
