Question

Sediments in and below a dewatered area of an aquifer become compacted because:A. water pressure drops and the pore spaces are closedB. water pressure increases and the pore spaces become too porousC. water pressure remains the same but the pore spaces become clogged with new sediments

Answer 1

Water pressure drops and the pore spaces are closed

Step-by-step explanation:

Pore pressure can be reduced in the aquifer that could result in compaction . and water pressure drops. Pore pressure is the pressure of the fluid in the pore space of the rock, and as mentioned above, when it exceeds the hydrostatic pressure, overpressure situation occurs.

Answer 2

Sediments in and below a dewatered area of an aquifer become compacted because: A) Water pressure drops and the pore spaces are closed

Step-by-step explanation:

Porosity and specific yield are the aquifer most important properties. Specific yield is responsible of giving its capacity to release the water in the pores and transmit the flow with no stress effort. When an aquifer area is dewatered, its pressure drops, and sediments used to clog pore spaces, making them to close.
