Plate Tectonics is supported by observations of similar geographic formations in South America and Africa, where the two continents look like they might fit together, and similar matchings elsewhere in the world. most importantly, however, plate tectonics is supported by the fact that we have actually measured the movement of the plates on an annual basis.
Until the mid twentieth century, the evidence consisted mostly of fossil similarities in areas that were considered to have been joined geographically earlier in Earth's history. No mechanism had been revealed, however, to explain why continents would move apart. In the 1950's, a scientific expedition was made to map the ocean floor. The exploration revealed a more or less continuous seismically active ridge in the middle of the Atlantic Ocean. Later, it was discovered, with the use of a magnetometer mounted in an airplane, that rock on either side of the ridge was chronologically a mirror image of the rock on the other side. This was due to the magnetic orientation of the Earth, which can abruptly change, being recorded in the rock at the time of its formation. This creation of new crust at the mic-ocean ridges was the mechanism for plate movement that had previously been undiscovered, leading to the understanding of lithospheric plate tectonics that we know today.
There is so much evidence that has been used to support the theory of plate tectonics. The discovery of similar rock masses and the shapes taken by the continents are the main proofs used.
the same fossils that were found in south america were also found in africa
fossils of the same species have been found on two different continents
The spreading of the sea floor.
Try the San Andreas fault.
no
The tectonic plate is called the African Plate.
No, plate boundaries is part of the explanation of the Plate Tectonic theory:)
The mountain range that is being created by the collision between the Indian tectonic plate and Asian tectonic plate is the Himalaya.
Yes, the singular form is normally plate tectonic or tectonic plate so the plural would be plate tectonics or tectonic plates. Dumb crap.
Tectonic plate are named after portions of the Earth that they support, such as the Eurasian Plate and the African Plate.

Tectonic plate boundaries
The continental drift theory and the plate tectonic theory
huh? what is a tectonic plate?
Plate Tectonics is the process by by which the earth's tectonic plates move.
The tectonic plate is called the African Plate.
No, plate boundaries is part of the explanation of the Plate Tectonic theory:)

tectonic plate for mt hood
The tectonic plate under parts of Europe and Asia is a continental crustal plate.
when tectonic plate collides with other tectonic plates or moves into another tectonic plate it affects surface in a way to create mountains. Like Himalayas are created when the indian tectonic plate collided with asian tectonic plate.
