The Theory of Plate Tectonics The Earth's lithosphere (crust and upper along the spreading center between the North American and Eurasian Plates, as North. Spreading centers for tectonic plates.
Noticed magnetic stripes on the ocean floor which proved that new crust was being created at these ocean ridges.
We know that these plates move in different ways.
