Continental drift
The principal force in action is the gravity.
continental drift? tectonic plate movement?
geologists believe the force may be caused by the collision of lithospheric plates.......
Basically, it's thought to be because of movements in the plastic mantle below the crust.
thermal convection
the movement of convection currents in the mantle is the cause of plate motion.
the movement of convection currents in the mantle is the cause of plate motion.
the movement of convection currents in the mantle is the cause of plate motion.
It's called the Continental Drift but scientists changed it to Plate Tectonics in 1960.
the movement of convection currents in the mantle is the cause of plate motion.
Continental drift :)
The convection forces of plate tectonics.
Plate tectonics.
The force is continental drift
Continental drift :)
Earhtquakes-because it shook the world, Vocanoes-because the magma melts the rocks and forms new land, etc. Its things like that, that caused Pangaea.(Pangaea-the continents drifted apart)
the movement of convection currents in the mantle is the cause of plate motion.
