It is outdated because it has one really, really big problem: there is no mechanism to explain why the continents drift. Wagner received a lot of flak from his fellow geologists, despite some goods facts he presented along with his theory. The Theory of Plate Tectonics, which has replaced the Theory of Continental Drift, uses the mechanism of mantle convection to explain why the continents "drift", and it has proved invaluable in explaining many more observations seen on the Earth.

Direct evidence for plate movement comes from the global positioning system. For the past 20-25 years we have been able to directly observe the Earth's tectonic plates moving around. This backs-up many other sources of geological evidence.

it is really true, here's the evidence:
satellite scans of the ocean's floor show lines which cut the earth into plates. we actually notice the movement of these plates by measuring them. (for example, at the San Andreas fault, it is getting larger by 6 feet a year [I think that's the distance, anyway...]) we also know these plates are moving, because when they move against one another or one goes under the other and *snaps*, it causes earthquakes at the spot. we've measured tons of earth quakes (there's a dozens of tiny quakes happening a day) and if you were to map the epicenters on a globe, it would make a stunningly accurate set of lines showing the locations of the borders of the earth's plates.

I think the Hydro-plate theory makes more sense.

.it's true it's in the rocks and the magnetic field.
