Tectonic tessellation playground. set one of the two positions (a or b) to adjust. these points are the beginning and end position for the animation. each land mass can be adjusted by modifying their x, y, and z axis rotation (this can be tedious). you may drag the earth to see different views. adjust the scale for positions a and b (in percent).
4 Theory Of Plate Tectonics In 1977, after decades of tediously collecting and mapping ocean sonar data, scientists began to see a fairly accurate picture of the seafloor emerge. the tharp heezen map illustrated the geological features that characterize the seafloor and became a crucial factor in the acceptance of the theories of plate tectonics and continental drift. today, these theories serve as the foundation upon. Plates move apart at mid ocean ridges where new seafloor forms. between the two plates is a rift valley. lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro. so the entire ridge system is made up of igneous rock that is either extrusive or intrusive. O lecture: forces driving plate motions. o lab: plate groups present, wrap up discussion. definitions. earth science’s grand unifying theory (or at least, one that works very well for many things) from “tekton” (greek, “builder”) tectonics does not necessarily equal plate tectonics. for 2 centuries, ideas had been formulated about how. Plate tectonics (from latin tectonicus, from ancient greek τεκτονικός (tektonikós) 'pertaining to building') [ 1 ] is the scientific theory that earth 's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. [ 2 ][ 3 ][ 4 ] the model builds on the concept of continental.

[ 2 ][ 3 ][ 4 ] the model builds on the concept of continental. In essence, plate tectonic theory is elegantly simple. earth ’s surface layer, 50 to 100 km (30 to 60 miles) thick, is rigid and is composed of a set of large and small plates. together, these plates constitute the lithosphere, from the greek lithos, meaning “ rock.”. the lithosphere rests on and slides over an underlying partially molten. Plate tectonics is a scientific theory that explains how major landforms are created as a result of earth’s subterranean movements. the theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. in plate tectonics, earth’s outermost.
