Alfred Wagner, the scientist from Germany that give us the theory of continental drift. Initially, it was rejected. Thirty years, later, Harry Hess provided the proof that Wagner was corrected.
The article explains one of the earliest ways geologists thought the continents move. It explains that Wagner is the one that continental drift is the one known for the theory. It explains the earth continents might have once been all fit together like a finished puzzle.
My video go deep into the information about the inside of the Earth and the different crusts. The four parts of Earth is the inner core, outer core, mantle, and the crusts. the plates are the crust and they float on the mantle. explains that the trenches form usually happen in the ocean.
My article explains the basic and more advance parts of plate tectonics. It explains that it is theory that Earth's outer shell is divided into several plates that glide over the mantle. It states that the theory was popular in 1950s through the 1970s. Plate tectonics is the modern version of continental drift. Scientists developed this theory by noticing how the continents are like giant puzzle pieces.
