The slow drifting of sections of the earth's crust, sometimes separating, other times colliding, is known as

Tectonic plate movement

Explanation:

The earth’s crust is divided into sections that move above the liquid mantle below. The driving force of this movement is the convection currents of the mantle. Tectonic plate movement shapes the earth’s crust. At convergent boundaries structures such as trenches and fold mountains are formed while at divergent boundaries, new crust is formed.
