The Difference Between Continental Drift and Plate Tectonic Theory

Plate Tectonics Theory- The upper most mantle, along with overlying crust, behaves as a strong, rigid layer. This layer is the lithosphere. The lithosphere is divided into moving segments that change.

Continental Drift Theory- Alfred Wegener proposed that parts of earths crust slowly drift atop a liquid core.

Continental Drift- Continents were once joined, moved through ocean floor not with it, do not use layers of earth

Plate Tectonics- Explains structure and internal workings, Plates move on the layers, Continents separate eachother

Evidence of Plate Tectonics- Hot material found deep in the faults, generates earthquakes, volcanoes, mountains, ridges etc. The slabs of boundaries descend into the mantle
