Pressure increases as you approach the ocean floor.
tidal wave starts by pressure in the oceans floor
The ancient oceans changes were made from the continental shift. The sea floor crusts and ground formations constantly moved and created deep canyons at the bottom of the oceans.

basalt
Earth's crust is composed of the continents and the ocean floor.
sea floor spreading
if the well pressure switch goes with the tank then the second floor pressure would more closely match the well pressure setpoints and the ground floor would have slightly higher pressure. with the tank and pressure switch on the lower floor the lower floor would more closely see the well pressure setpoints and the second floor would get slightly lower pressure.
age increases
basalt is the common rock
