Frequently Asked Questions

What evidence is there to support the plate tectonics theory?

Evidence for plate tectonic theory. There are three main pieces of evidence that support plate tectonic theory the first is the age of the earth’s crust showing that new rock has been formed and it still likely to be forming.

What are the arguments against the theory of plate tectonics?

One major argument that some scientists had against the plate tectonic theory in the early 1960's was the existence of volcanically active areas located in the middle of plates instead of near a subduction zone. The lack of explanation was addressed by Wilson in 1963 with his introduction of hotspots.

What does the theory of plate tectonics help to explain?

Plate tectonics is an important geologic concept as it fills in the gaps to Earth's geologic history. The theory of plate tectonics helps explain the formation of mountain ranges, volcanism, earthquakes and the features associated with active plate boundaries.

What is the theory of plate tectonics and when did it evolved?

In line with other previous and contemporaneous proposals, in 1912 the meteorologist Alfred Wegener amply described what he called continental drift, expanded in his 1915 book The Origin of Continents and Oceans and the scientific debate started that would end up fifty years later in the theory of plate tectonics.
