Two words - plate tectonics - describe the theory that the surface of the earth is in constant motion.
alfred wegner theory
your so stupid u cant answer the question
Plate Tectonics
Convection currents.
Plates of the lithosphere do not float on the core. They float on the asthenosphere (plastic mantle). Due to convection currents and the earths rotation, plates glide over the asthenosphere. This theory is the theory of Plate Tectonics.
The plate tectonic theory states that new Earth crust is being formed while old crust descends back into the mantle. Uneven heating in the mantle causes convection which keeps the crust in motion. The constant movement of Earth's plates are the result of the three types of boundaries, divergent, convergent, and transform, and the convection in the mantle.
That is the current theory of plate tectonics.
The theory of plate tectonics describes how plates move. The main driving force is convection currents in the mantle.

A brief description of plate tectonics would be the theory that parts of Earth's lithosphere are always in motion, driven by the convection currents inside the mantle.

Plate Tectonics
The theory of plate tectonics states that the lithosphere is broken into moving pieces of earth driven by convection currents located inside the mantle.
That is the current theory of plate tectonics.

Plate Tectonics
The theory of plate tectonics describes how plates move. The main driving force is convection currents in the mantle.
The lithosphere is broken into about 100 separate sections called tectonic or crustal plates. They are divided by faults which are very much like cracks between plates. These plates float on top of the asthenosphere. A rift valley is a deep valley that forms where two plates move apart.
The movement of crustal or lithospheric plates is a part of the theory of plate tectonics.
