Apr 05, 2020 · When Alfred Wegener first made his case for continental drift, he relied on two main lines of argument: the shape of the continents and the relative positions of glacial till deposits. Evidence later accumulated from other areas of research, but the theory was not taken seriously until well after Wegener's death.
Jan 03, 2011 · The discovery of this fossil, along with other specimens of Lystrosaurus, was instrumental in providing the scientific proof needed to validate the theory of continental drift. In 1912, German scientist Alfred Wegener officially proposed a theory of continental drift.
Continental Drift Alfred Wegener. Continental Drift. The theory • In 1912, Alfred Wegener and Frank Taylor first proposed the theory that 200 million years ago the Earth had only one giant continent, from which today's continents broke apart and drifted into their current locations.

Continental Drift: Recreating Pangaea. Wegener and Du Toit’s theory: German scientist Alfred Wegener developed a theory that approximately 245 million years ago, the continents once formed a giant supercontinent that he called Pangaea. Later, South African geologist Alexander Du Toit theorized that Pangaea divided into two supercontinents 205 million years ago.

List and Describe the Evidence for the Plate Tectonics Theory. Plate tectonics theory is taught in science classrooms around the world, but just 50 years ago it was a hotly contested theory. The idea that the Earth’s crust is made up of huge tectonic plates that are floating on an ocean of molten hot magma seemed too ...

However, in the 1950s, evidence started to trickle in that made continental drift a more viable idea. By the 1960s, scientists had amassed enough evidence to support the missing mechanism—namely, seafloor spreading—for Wegener’s hypothesis of continental drift to be accepted as the theory of plate tectonics.

Continental Drift and Plate Tectonics Continental Drift As far back as 1620, Francis Bacon spotted that the west coast of Africa and the east coast of South America looked as if they would fit together, like pieces of a jigsaw puzzle.

It is a good way to represent continental drift and understanding how evidence allowed scientists to produce the theory of continental drift. Description This activity is a kinesthetic activity where students will use logic and evidence to reconstruct the position of large islands and continents as they appeared 220 million years ago.

The widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica, and Australia was one of the major pieces of evidence for the theory of continental drift.

Dec 11, 2019 · Gondwana and Rodinia are two supercontinents that scientists support the existence of that were probably around prior to Pangea. Scientists predict that supercontinents will continue to appear. Today, the world's continents are slowly moving away from the Mid-Atlantic Ridge toward the middle of the Pacific Ocean.
