Plate Tectonics Theory BY: Camryn sesko & Meliyah faison

Plate Tectonics are Earth's outer shell consists of individual plates that move in various ways and produce earthquakes, volcanoes, mountains, and the crust itself.

Continental Drift is a hypothesis that the continents joined into a super continent called Pangea, and then the super continent broke into pieces which drifted into their present day position. The plate tectonic theory is different because it is plates under the continents that are shifting.

The Plate Tectonics theory can be supported by the geological features it creates such as, mountains, volcanoes, rivers, oceans, etc. Plate tectonics create these features by converging, diverging, and transforming in various directions.

This is evidence that pate tectonics have occurred. The India plate subducted under the Eurasian plate and created the Himalayas.

Evidence for plate tectonics are Paleomagnetism which are rocks that were formed millions of years ago that show the location of magnetic poles at the time of their formation.

Another piece of evidence for plate tectonics is earthquake patterns which is when the depths of earthquake foci and their locations within the trench systems are plotted, a pattern emerges.

This is an example of earthquake patterns where it shows where earthquakes have occurred the most.

Another piece of evidence is ocean drilling which is the most convincing evidence of plate tectonics. When the oldest sediment from each site was plotted against its distance from the ridge crest, it was revealed that the age of the sediment increasing distance with the ridge.

Hot spots are the last piece of evidence for plate tectonics which are melting of hot rocks as it nears the surface it creates a volcanic area, or hot spot
