an artesian well.
the hydraulic gradient.
a geyser.
The two factors that influence the curved route of infiltrated water flow underground are:
gravity and hydraulic pressure.
gravity and electromagnetism.
the Coriolis Effect and the prevailing winds.
permeability and non-permeability.
Which of the following are wells used for? CHOOSE ALL THAT APPLY!
Wells are used to determine the height of the water table.
Wells are used to obtain water for crop irrigation.
Wells are used to obtain water for human consumption.
Wells are used to create barriers between aquifers, called aquatards.
What does the quantity of groundwater that can be stored depend upon?
It depends upon the porosity of the underground rock.
It depends upon the pH of the groundwater.
It depends upon the underground depth of the storage system.
It depends upon the temperature of the underground rock.
A place where the water table intersects the ground surface and where a natural flow of groundwater results is called:
a spring.
a geyser.
an aquatard.
a fissure.
What is the source of heat for hot springs?
It is provided by the cooling of igneous rock.
It is provided by the transformation of metamorphic rock to sedimentary rock.
It is provided by the warming process of soil moisture.
It is provided by plate subduction at convergent boundaries.
What is the most common method for removing groundwater?
a well bored into the zone of saturation

Which of these images depict a Karst landscape? CHOOSE ALL THAT APPLY!
Identify which of the following are required to make a major cavern system. CHOOSE ALL THAT ARE NECESSARY.
Groundwater is often mildly acidic as it contains a weak solution of carbonic acid.
The acidic nature of groundwater will dissolve the calcite in limestone.
Caverns are formed by dissolving rock beneath the Earth’s surface.
Plate subduction can create caverns as one plate dives under another.
Which of the following IS NOT a dripstone feature?
sinkholes in Karst topography
stalactites hanging from the ceiling of caverns
