More typical deep sea rates are on the order of several centimeters per 1 000 years.
The deepest segments of the ocean floor are found covered by clay and the skeletal remains of microplankton.
Sediment can accumulate as slowly as 0 1 millimeter 0 04 inch per 1 000 years in the middle of the ocean where only wind blown material is deposited to as fast as 1 meter 3 25 feet per year along continental margins.

Oceanic trenches are a distinctive morphological feature of convergent plate boundaries along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year.
