Convection movements; currents in Earth's interior. Note that a significant part of Earth's interior is liquid.

the movement of tectonic plates
volcanos and earthquakes
Scientists speculate that the movement of tectonic plates is created by the movement of the rigid lithosphere on the asthenosphere.

sea-floor spreading
Earthquakes. Pressure in the Earth's core.
the movement of the earth's plates under ground
The Earth's crust, known as the lithosphere, is broken into segments known as plates. The movement of the plates over the asthenosphere causes the plates to change position altering Earth's surface.
the sea-floor spreading, and the movement of tectonic plates
The Movement of Techtonic Plates causes the earthquakes in Japan.
