On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. 2023 EduBirdie.com. However, you may visit "Cookie Settings" to provide a controlled consent. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. How did Alfred Wegener come up with the idea of continental drift? Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it. backlog intangible asset; west metro fire union contract. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Lived 1880 - 1930.

The rock formations of eastern North America Western Europe and northwestern Africa were later found to have a common origin and they overlapped in time with the presence of Gondwanaland. Since these match up points consisted of the same kind of rock further proves that the continents were once together before breaking away and drifting. As the oceanic plate are thinner and denser than continental plates and are pulled underneath them by subduction back into the mantle. The continents were once joined in a super-continent and have moved over time. There are two varieties of tectonic plates: Oceanic plates and Continental plates.

Continental plates are slightly less dense (2.6-2.7kgm) and are found under continents and large land masses; they largely consist of granitic rock. Continental Drift: The movement of continents across the ocean bed is known as continental drift. This theory has explained the origin of continents and ocean basins. He discovered glacier groves in continents that were not cold enough to support snow formation in the present day. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? A graphic of Gondwana.
