Granite can be excluded from the list of underground materials that hold water in the Ogallala aquifer. Unlike gravel, sand, and silt, granite is not porous and does not hold water well.

The correct answer is subsidence. Subsidence refers to the sinking of the surface when a large amount of water is withdrawn from an aquifer.
Which becomes a problem when mining groundwater continues?(1 point)
Responses
It becomes too expensive to maintain the aquifer.
It becomes too expensive to maintain the aquifer.
It adds pollution to wells.
It adds pollution to wells.
It removes water more quickly than it can be replaced.
It removes water more quickly than it can be replaced.
It causes porous rock to suddenly harden.

It causes porous rock to suddenly harden.
It causes porous rock to suddenly harden.
The correct answer is It removes water more quickly than it can be replaced. This describes a significant problem associated with continued groundwater extraction, as it can lead to depletion of the aquifer.
What might happen if there is excessive water removal from the Central Valley Aquifer in California?(1 point)

It could cause faults to be less stable, resulting in earthquakes.
The correct answer is It could cause faults to be less stable, resulting in earthquakes. Excessive withdrawal of groundwater can lead to land subsidence and may affect the stability of geological structures, potentially increasing the risk of earthquakes.
