Which of the following is NOT true about groundwater flow?

A) in some igneous groundwater reservoirs, flow is determined by the orientation of fractures
B) excess pumping from wells can cause subsidence and reduction of porosity
C) a decrease in the gradient slope of the water table) increases the velocity
D) water moves from areas where the water table is highest to areas where it is lowest

Groundwater Flow

The movement of water through the pore spaces and fractures in underground soil and rock layers.

Subsidence

The gradual sinking of the ground's surface, which can occur due to natural processes like the compacting of sediment or human activities such as groundwater extraction.

Gradient

A measure of how one quantity changes or varies over distance or another quantity, often expressed as a slope or rate of incline.
