1The water table separates
- Athe zone of porosity from the zone of permeability
- Ban aquifer from an aquiclude
- Cthe zone of saturation from the zone of underlying aeration
- Dthe zone of aeration from the underlying zone of saturation
2Ground water
- Ain general moves very rapidly through pore spaces of materials in the subsurface
- Bcan move upward against the force of gravity
- Cmoves from areas of low pressure toward areas of high pressure
- Dall of these
3A perched water table
- Aoccurs whenever there is a localized aquiclude within an aquifer
- Bindicates the presence of a cave
- Call of these
- Dlacks a zone of aeration
4Karst topography is characterized by
- Aintegrated drainage systems
- Bhot springs
- Csinkholes
- Dthe presence of caves
5Artesian ground-water systems are characterized by
- Arise of water above the level of a confined aquifer if a well is drilled into the aquifer
- Bhigh salinity of the water
- Ccontinuous discharge of water at the surface
- Dhorizontal or flat-lying piezometric or artesian pressure surface
6The water table near a large pumping well
- Aassumes a cone of depression
- Bproduces a cavernous feature
- Cis raised by capillary action
- Dincreases the porosity of the aquifer
7One of the following is always a poor aquifer
- Agranite
- Bsandstone
- Climestone
- Dfractured basalt
8The rate of flow of much of shallow ground water is generally on the order of
- Acentimeters or may be one or two meters per day
- Bcentimeters or may be one or two meters per century
- Cfew hundred meters to about a kilometer per day
- Dmore than a kilometer per day
9Hard water contains relatively large amounts of
- Acalcium and magnesium ions
- Biron and sulfur
- Ccarbonic acid
- Dpotassium and sodium
10Darcy’s law basically states that
- Athe size of sinkholes is related to the amount of subsurface flow
- Bsinkhole spacing is related to relief of the land
- Cflow in an artesian system is dependent on the thickness of the aquicludes
- Dthe volume of ground water flowing in a specified amount of time is proportional to the vertical drop in the height of the water table between two points divided by the horizontal distance between the two points
11Caves form in a terrain or region where the rocks are essentially
- Alimestone
- Bsandstone
- Cshale
- Dinterlayered shale and sandstone
12Stalactites and stalagmites form as drops of water from the ceiling of a cave
- Alose dissolved carbon dioxide by entering into the cave with the atmospheric air
- Bevaporate rapidly due to warm temperature in the cave
- Cbecome more oxygenated
- Dbecome less oxygenated
13Stalagmites and stalactites are made up of
- Acalcite
- Bquartz
- Cgypsum
- Dclay minerals
14If an excessive pumping of ground water in a coastal area lowers the water table at a locality by 0.5 meter, the contact between the fresh ground water and the salty ground water in the locality will
- Arise by 20 meters
- Brise by 10 meters
- Cdrop by 20 meters
- Ddrop by 10 meters
15The leaning of the Pisa Tower in Italy was caused by
- Aclimatic change which lowered the water table
- Bconsolidation of the ground material by rapid ground water depletion
- Cction of the subsurface materials following repeated earthquakes
- Dlack of coherence of materials due to continued rise in the sea level
16Which rock type among the following would make the best aquifer
- Awell sorted sandstone
- Bpoorly sorted sandstone
- Cshale
- Dpoorly sorted siltstone
17The permeability of a rock system depends on several things except
- Athickness of the rock system
- Bamount of porosity of the system
- Csize of the individual pores within the rock system
- Dinterconnection among the pores
18Development of geysers requires that
- Athe ground water must be circulated very deep within the earth so that the water attains a temperature above the boiling point
- Bthe ground water be heated to a temperature above boiling and be within a non-confined system
- Cthe ground water partly be heated at a temperature above boiling and partly with a cap of a layer of cold water within a reservoir that offers limited convective mixing of the water
- Dwater comes from a magmatic source
