Plate Tectonics Evidence!

Glacial deposits: Glacial deposits are formed by Glaciers that erode and pick up material, it then releases that material to let it be deposited on underlying surfaces or surrounding areas. It can occur directly from the glacier itself or from few other processes involving the glacier’s melt water. Glaciers are formed by the tectonic plate moving and breaking the ice, and the glaciers form the glacial deposits.

Geologic Fit: Geologic Fit is the theory of when two or more opposing coastlines or landmasses on a map have an appearance of being able to connect or “fit” together. An example of this theory is the coastlines of Africa and South America fitting together to form the ancient landmass of Pangaea. There are many other examples of geological fit, such as similar mountain ranges on different continents.

Jigsaw Fit: Jigsaw Fit is a theory of the continents being able to "fit" together. This theory is related to the plate tectonics moving and splitting the continents apart (continental drift). Scientists named this theory "jigsaw" because they could piece the continents together like a puzzle.

Paleomagnetism: This is study of records in the Earth’s magnetic field in rocks,sediments, and archaeological material (fossils). Minerals in these rocks contain a record of the direction of the magnetic field when they form. This record provides information of the past behavior and movements of the magnetic field and also the past locations of tectonic plates.

Fossils: Many dinosaurs and many ancient plants were presented in the land-form of Pangaea. Fossil evidence is found in all of the different continents, and most of them match up to the same species throughout the coastlines from when it was once conjoined. If the continental drift had not occurred, the specimens would have lived independently on each continent, according to Darwin’s theory of evolution.

Earthquakes: Earthquakes are the byproducts of two or more tectonic plates moving and sliding against each other. Earthquakes are more likely to occur near and around fault lines. Fault lines are usually found in or near the equator, where the earthquakes form and destroy.

Ocean Floor Mapping: Before ocean floor mapping,people thought that the sea floor was relatively flat,and there was a lot of sediment on the bottom. "Modern" measurements of ocean depths increased in the 1800's, in that time, scientists revealed the first evidence of underwater mountains in the central Atlantic Ocean. The underwater mountain ranges appear around the fault lines of tectonic plates.
