Question

When water is pumped from the subsurface it decreases the ____________ pressure within sedimentary materials, forcing the solid particles to support more of the weight.

Answer 1

Answer: pore or fluid

Explanation: The pore or fluid pressure is the pressure of the fluid within the pores of a given rock. The pore pressure can result in a situation known as overpressure or high pore pressure when the pore pressure becomes higher than the hydrostatic pressure.

Sedimentary materials are particles which have been accumulating over a long time and have been cemented together through temperature and pressure etc.
