The document provides evidence for plate tectonics, including Wegener's early ideas about fitting continents together which lacked an explanation for the mechanism of movement, followed by new evidence such as seafloor spreading detected through ocean drilling and patterns in earthquakes and hot spots that support the theory of plates moving due to processes like mantle convection, ridge push and slab pull.
