World's Only Moving Mud Puddle

The simple vesion..version...

below the puddle is a normal water table

water erodes

the water often times will hollow out a chamber with a ceiling, floor and walls

moving water erodes faster

CO2 is an acid when combined with water (H2CO3)

undissolved CO2 moving through water creates water currents 

acidic moving water will dissolve  rock in the path of least resistance 

fractured rock is the path of least resistance 

the gas is working like a saw to cut through rock

once the CO2 can rise straight up,  it will quit cutting/ dissolving the rock and the puddle will quit moving

they have the right idea, vent the gas closer to the point or origin on the other side if the infrastructure 


but...

the ground  is now unstable  under all if it...


I'm not  a geologist, I am a nurse and CO2 is an acid in our body and our body keeps a tight hold on pH.

the medulla controls breathing to rid us of high CO2 or hold on to more CO2 when we are too alkaline 

the kidneys counter the acidic CO2 with bicarbonate (HCO3) and can excrete excess bicarbonate when we are too alkaline, or excess hydrogen ions when we are too acidic 

the lungs are faster at changing the  balance 

it's funny how some knowledge  transfers
