The largest reservoir of water on Earth is:
The ocean
The conditions necessary for cave formation exist at countless places on the Earth, yet caves are a relatively rare phenomenon. Which of the following conditions is MOST necessary for cave formation?
Presence of a soluble rock type.
Storage of high-level nuclear wastes requires that all of the following conditions exist at the proposed site, EXCEPT:
Burial within the saturated zone.
Gaining streams are those where:
Water from the saturated zone flows into the stream.
Porosity is:
The percentage of a rock's volume that is open space
Groundwater flows:
From areas of high hydraulic head to areas of low hydraulic head.
An aquifer is
A body of saturated rock or sediment through which water can move easily
Permeability is:
The capacity of a rock to transmit fluids.
Caves and cavern systems are formed by:
Groundwater dissolving limestone and dolomite
The amount of void space in a sample of fractured limestone is 312 cubic centimenters. The volume of the sample is 2000 cubic centimeters; thus the porosity of the limestone is
An artesian well is one:
That rises above the surface of the aquifer without pumping.
The top of the water saturated zone is known as:
The water table
Geysers and hot springs
Are caused by groundwater being geothermally heated
Spring water flowing from an unconfined aquifer on a hillside is:
Likely to be contaminated.
An example of a rock that may have high porosity but essentially zero permeability is
The near-surface zone where all pores are filled with water is called:
The saturated zone
A spring forms:
Where the water table intersects the land surface
Which rock type below is likely to possess the highest permeability?
The decline in the level of the water table around a pumping well is known as:
The cone of depression
