The modern theory of plate tectonics explains Formation, subduction and movement of Earth's Plates. There were some theories over the last 100 years that have led scientist to the modern theories of plate tectonics, One theory was continental drift. Alfred Wegener, in 1920, thought that the continents were shaped like puzzle pieces that would have fit together so he started to collect.
Plate tectonics is a recently developed science, and it can be used to explain a lot of phenomena on the Earth, such as earthquakes. There are actually two big fundamental theories of plate tectonics. One of the basic theories is called continental drift, and the other one is the theory of seafloor spreading. The theory of continental drift can not explain the power source of moving continents.
Plate tectonics is the geologic theory that the Earth's crust is made up of rigid plates. Some examples of tectonic plates are the African Plate, the Antarctic Plate, the Eurasian Plate and the.Learn More
After reading this essay you will learn about the plate tectonics theory. Plate Tectonic theory is based on an earth model characterized by a small number of lithospheric plates, 70 to 250 km (40 to 150 mi) thick, that float on a viscous under-layer called the asthenosphere. These plates, which cover the entire surface of the earth and contain.Learn More
Plate Tectonics Plate Tectonics Plate Tectonics Prior to World War II, humans were conformed with the idea that the Earth and its continents had been basically unchanged since the beginning of time. A German meteorologist, Alfred Wegener observed that the coastlines of the seven continents could be fitted together almost perfectly like a jigsaw puzzle. If fitted together, the geological dating.Learn More
Plate tectonics is a combination of two ideas, sea-floor spreading and continental drift. The creation of new oceanic crust at mid-ocean ridges is called sea-floor spreading. In 1969, spreading plate margins became part of the theory of plate tectonics. This theory explains not only about how ancient crust is destroyed along destructive plate margins, but it also explains how new ocean floor.Learn More

Essay Question 1: Compare and contrast the topographical features at divergent and convergent plate margins. Subject: Earth Environments 1: Geomorphology and Soils Course Code: GEOG 1231 Divergent and convergent plate margins are both studied in plate tectonics; which is the study of the plates that makeup the lithosphere, their movements and how these movements has influenced changes in the.Learn More
The plate tectonics tells us that the earth’s crust is broken into two different types of plates known as the oceanic and continental plates. These plates can slides over each other and are floating over the uppermost layer of the mantel and convection cells. The plates are in constant motion. Along their margins where they usually interact, important process such as the formation of.Learn More
Although we have found much on plate tectonics, there are still some unanswered questions. The depths of the plates are still unknown. Scientists are still unsure on how the motion of the mantle was initiated. There are many theories on how plate tectonics works and why the polarization of the Earth switches every million years but there have been no concrete facts.Learn More
