GEOLOGY

Detailed explanation-1: -Alfred Wegener in Greenland. Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.

Detailed explanation-2: -Wegener was a German meteorologist, geophysicist and polar researcher. In 1915 he published ‘The Origin of Continents and Oceans’, which outlined his theory of Continental Drift. Wegener was a member of four expeditions to Greenland.

Detailed explanation-3: -69 10.1 Alfred Wegener-the Father of Plate Tectonics Alfred Wegener (1880-1930) (Figure 10.1) earned a PhD in astronomy at the University of Berlin in 1904, but he had always been interested in geophysics and meteorology and spent most of his academic career working in meteorology.

Detailed explanation-4: -In 1910 Frank Taylor published a theory of continental drift. He suggested that in the past the Earth had been spherical with massive continents at the poles. His theory was that these continents had been dragged apart by gravity when at some point in geological history the Earth captured its moon.

Detailed explanation-5: -Alfred Wegener’s curiosity toward the possibility of continental drift came in 1910 after he noticed how Earth’s continents resembled pieces of a jigsaw puzzle. For example, he noted how South America coast correctly lined up with the coast of Northwest Africa.
