Earth science chapter 14 review
Landscapes that have been shaped largely by the dissolving power of groundwater are said to have
karst topography
The upper limit of the zone of saturation is called the
watertable
Which of the following is measure of material's ability to transmit fluids through interconnected pore spaces
: C, permeability
Springs form where
: D, the water table intersects the ground surface
Permeable rock layers or sediments that transmit groundwater freely are called
A, aquifers
A cavern is an underground chamber formed by:
A, erosion
Which type of rock usually underlies a karst landscape
A, limestone
Sinkholes can form when
A, rainwater containing carbon dioxide dissolves underground rock
Groundwater contaminated by sewage from ruptured septic tank can sometimes be naturally purified by flowing for a relatively short distance through a:
A, sandstone aquifer
What features will be formed along the hillside at or near the area Labeled A in Figure 6-2
A, springs
Which of the following statements is true about stalactites
A, they hang from the ceiling of a cavern

Which of the following is NOT a major source of groundwater pollution
B compost
When groundwater enters underground fractures or caverns in hot igneous rocks, where it is heated to boiling temperatures, what feature can form
B geyser
What does groundwater naturally contain that allows it to dissolve limestone and form caverns:
C
Caverns most commonly form in what type of bedrock
C, limestone
In figure 6-2, what letter labels the zone of saturation
D
What feature is labeled in C in FIgure 6-2:
D The Water Table
The percentage of the total volume of rock or sediment that consists of pore spaces is called:
D, porosity
Which of the landforms is NOT common in an area of karst topography
D, surface drainage system
Describe ways in which groundwater may become polluted
Spills, littering, human activity
Groundwater is found underground in the zone of
c, saturation
A scientist discovers that a rock layer is permeable but contains very little groundwater: How can this occur:
The rock can hold water but nothing is in it can be a drought, to much usage, the size of the air holes might be to small pore space is to small
The ability of a stream to erode and transport material depends largely on its
Velocity
Which of the following is associated with areas of karst topography
d, all of the above
An intermittent hot spring in which a column of water shoot up with great force at various intervals is a(n)
geyser
Groundwater pollution can be caused by leaking septic systems, leaking landfills and agricultural chemicals
pollution
Caverns form at or below the water table in the zone of saturation, but drip stone features in caverns form above the water able in the zone of:
saturation
