Exam 15: Groundwater and Karst Landscapes

With increasing precipitation,pore spaces fill with hygroscopic water.

The cone of depression occurs when the water table is lowered in regions surrounding the water well.

The area between the soil-water belt and the water table where pore spaces are not saturated with water is called

__________ also plays a role in eroding limestone deposits by providing organic acids that enhance the solution process.

A geological formation that contains a suitable amount of water to be accessed for human use is called a(n)

__________ is the top of the saturated zone.

Sinkholes form when caves enlarge so much that their ceilings collapse due to the force of gravity.

When the pore spaces between sediment become too small and do not allow water to pass through,the sediment is said to be

The High Plains (a.k.a.Ogallala)Aquifer underlies portions of ____ states in the central United States.

When pore spaces become completely filled with water,the soil is considered to be at __________ capacity.

A region that contains solution caves and other soluble rock features is called

One of the components of the groundwater model is overland flow.

One way to limit the loss of water from an aquifer is to allow the fields to be left fallow.

The most heavily utilized aquifer in North America is the

These cave features form as a result of water evaporating,leaving the calcium behind in a deposit that slowly grows up from the floor over time.

The sinking of a surface as a result of the loss of water from an aquifer is called subsidence.

The High Plains Aquifer is largely formed from thin,impermeable layers of rock.

A geological formation that contains an unusual amount of water accessible for human use is called an aquifer.

__________ is the name of water that moves upward through the unsaturation zone.

As water moves down into the soil,it first moves through the zone of saturation.
