Instead, Wegener proposed that the animal lived within the rivers and lakes of a singular landmass which later broke apart. Other fossil … WebbContinental drift is defined as the motion of continents relative to each other and with respect to the Earth’s mantle. It is a striking feature of the Earth’s tectonic evolution throughout the Cenozoic and Mesozoic and is ubiquitous in plate reconstructions spanning these eons (see Torsvik and Cocks, 2024; Torsvik, 2024 ).

WebbData Supporting Continental Drift Theory. Studies of magnetic rocks in the 1950’s further confirmed Wegener’s theory. As lava cools, or as sediments are deposited, iron tends to align magnetically with the earth’s magnetic field. If the continents were stationary, the iron-bearing rocks would all have the same orientation. WebbKeep in mind that the Continental Drift Theory states that the movement of the Earth's continents relative to each other by appearing to drift across the ocean bed.

Continental drift - Wikipedia
Webb17 sep. 2024 · Continental Drift Theory (CDT) Continental drift refers to the movement of the continents relative to each other. Polar wandering (similar to Continental Drift Theory) Polar wandering is the relative movement of the earth’s crust and upper mantle with respect to the rotational poles of the earth. WebbContinental Drift Theory was put forward by the German scientist Alfred Wegner in 1915. According to the Continental Drift Theory, part of the crust are capable of horizontal … WebbWhen a continent opens, two of the rifts separate and become part of an ocean. The third rift aborts and is known as a “failed” arm. Examples of failed arms associated with the opening of the Atlantic Ocean are the St. Lawrence River Valley Rift and the Niger Rift in Africa.
