The earth's surface is broken up into many moving pieces called lithospheric plates. These consist of both continental and oceanic plates. These plates move around over millions and millions of years through a process called mantle convection. Essentially, hot magma rises, cools, and sinks due to a higher density. This creates a cycle-type motion, which moves the plates along. When plates collide, they create different types of boundaries, but that isn't necessarily important to your question.
Tectonic Plates
As a rock is falling through the atmosphere, it is a meteor. When it hits the earths surface, it is a meteoroid.

A volcano is the opening called in the earths crust called through which lava gases and other pieces of rock erupt.
Lithospheric plates are a number of rigid but moving pieces of earths surface.
The answer is tectonic plates floating on the lithosphere. Does that answer your question? LOL :)

Asteroids
The process is called erosion.
