Pressure is force magnitude applied over an area.
Overburden pressure is a geology term that denotes the pressure caused by the weight of the overlying layers of material at a specific depth under the earth's surface.
[2] In a stratigraphic layer that is in hydrostatic equilibrium; the overburden pressure at a depth z, assuming the magnitude of the gravity acceleration is approximately constant, is given by:
[2] where: In deep-earth geophysics/geodynamics, gravitational acceleration varies significantly over depth and
