<span>Juan de Onate was the explorer who first visited the US river, the river is the Rio Grande. In 1598 he crossed the Rio Grande at El Paso. From there he sent out small parties in all directions to search for treasure that did not exist</span>
The theory of continental drift by Alfred Wegener states that all land masses were originally united
in a single supercontinent known as Pangaea (250 million years ago). He shows
evidences like continental fit, similarity of rock sequences, glacial till and
striations, fossils (cynogathus-land reptile, lystrosaurus-land reptile,
mesosaraus-freshwater reptile, glossopteris-fern plant) to support his theory but
what was lacking is that it lacked a mechanism to explain HOW the continents
moved apart. But Harry Hess, a geologist and Navy submarine commander during
WWII <span>brought up a new
evidence to add in support of Wegener’s theory: the idea of seafloor spreading and magnetic reversals.</span>
