Chapter 14 Lab Textbook Reading and Review Questions

(Q008) The water table is lowered

during periods of drought.

(Q005) Properties required for a material to be an aquifer include

high porosity and high permeability.

(Q006) Properties required for a material to be an aquitard include

very low permeability.

(Q004) When does groundwater deposition occur?

when water evaporates, leaving a chemical sediment

(Q007) The water table separates

a zone where all pores are saturated with water from one in which some are filled with air.

(Q014) To conserve the groundwater supply, fields and gardens should be irrigated

at night to minimize evaporation

(Q002) Groundwater is unique among all the erosional agents because it

carves landscapes from below the surface

(Q011) What most likely will happen if the water table is at the surface of the ground?

All of the possible answers are correct.

(Q013) What may happen to a contaminant if it enters the groundwater in an area?

It may become a problem for those using groundwater for their homes.

(Q009) If the water table in an area drops below the level of stream channels,

stream levels will drop as water leaks from the streams into the ground.

(Q001) Groundwater is the part of the hydrosphere in which water does which of the following?

all of the possible answers are correc

(Q003) By what process is groundwater erosion accomplished?

dissolution of soluble rock types

(Q010) A cone of depression

forms locally when a user removes groundwater.

(Q012) Sinkholes typically have steep-walled sides because

gravity causes the roof of an area hollowed by solution to collapse.

(Q015) The basic principle in hydrofracturing (fracking) for petroleum and gas is that it

increases permeability, making it easier to extract oil and gas.
