Chapter 16
The layer of an aquifer in which the pore space is completely filled with water is called the zone of aeration saturation recharge porosity
A natural flow of groundwater to Earth’s surface is called a(n) well caprock spring cone of depression
Open spaces in rock must be connected in order for the rock to be packed porous fractured permeable
Carbonic acid breaks down minerals in rock in a process called sorting capillary action saturation chemical weathering
The amount of uniformity in the size of a rock or sediment particles is called packing sorting permeability cracking
Which of the following does NOT affect the depth of the water table below the ground? surface topography permeability of the aquifer pollution rainfall
The area where water from the surface can move through permeable rock to reach an aquifer is called a recharge zone water table well gradient
Which of the following does NOT affect the flow of groundwater through an aquifer? porosity gradient chemical weathering permeability
