How is continental drift different from plate tectonics?

• Continental drift is the theory of how the continents have moved, while plate tectonics is the theory of how the Earth's lithosphere is divided into plates and their movement.
• They are the same thing.

• Continental drift is the theory of how the continents have rotated on their axis, while plate tectonics is the theory of how Earth's plates stay in the same place.

• Continental drift is the theory of how the continents have sunk into the ocean, while plate tectonics is the theory of how the plates collide.

Why do the tectonic plates move?

• Gravity pulling the plates apart
• Magnetic forces pushing the plates
• Convection currents caused by heat from the Earth's core
• Friction between the plates
