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

Any formation in which groundwater rises on its own under pressure is a(n):

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
