Plate Tectonics Definition Theory Types Facts Evidence What do we mean by plate tectonics? the paleomagnetic proof of continental drift (plate tectonics) and the discovery of sea floor spreading set off a scientific revolution in geology in the 1960s and 1970s. geologists realised that many of their existing interpretations of global geology, based on the premise that the positions of continents. 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.
Learning Geology What Do We Mean By Plate Tectonics 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. Thus, plate tectonics is a scientific theory that deals with the large scale motion of the plates that makes up the earth’s lithosphere. from the deepest trench of oceans to the highest mountains, plate tectonics explains the movement of earth’s surface in the past and present. according to the theory of plate tectonics, the earth’s outer. The theory of plate tectonics states that earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. each type of plate boundary generates distinct. Key to understanding plate tectonics is an understanding of earth’s internal structure, which is illustrated in figure 1.5.1 1.5. 1. earth’s core consists mostly of iron. the outer core is hot enough for the iron to be liquid. the inner core—although even hotter—is under so much pressure that it is solid.

Introduction. plate tectonics has revolutionized the way we view large features on the surface of the earth. earth’s internal processes were previously thought to operate in a vertical fashion, with continents, oceans, and mountain ranges bobbing up and down, without much sideways movement. but the acceptance of continental drift and other. Map showing tectonic plate boundaries and geological activity around plate boundaries. before the 1960s, it was thought that continents were set in the same position forever. realising the plates are dynamic led to new insights into our understanding of the planet and revolutionised and unified the earth sciences – from the study of fossils.
