Alfred Wegener He hypothesized about 300 MYA the Earth had only one giant continent called Pangaea (meaning “all lands”) Published The Origin of Continents and Oceans in 1915 Evidence supporting the theory: Puzzle-Like Fit Fossil records Rock sequences Climates and changing polar regions Mountain ...
Below a depth of 660 km, evidence suggests that atoms rearrange yet again to form an even denser crystal structure. This can be seen using body waves from earthquakes, which are converted, reflected or refracted at the boundary, and predicted from mineral physics, as the phase changes are ...
