Chapter 14 - Lab Textbook Reading and Review Questions

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

NOT

Properties required for a material to be an aquifer include

high porosity and high permeability.

The water table is lowered

NOT -as plates spread farther apart in divergent boundaries.

A cone of depression

NOT -can increase the amount of water available regionally.

Properties required for a material to be an aquitard include

NOT -very high permeability.

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

NOT -during the afternoon to increase evaporation.

Groundwater is unique among all the erosional agents because it

NOT -has more kinetic energy than streams or glaciers.

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

NOT -increases surface area in pores, allowing water to escape and making more room for oil and gas.

When does groundwater deposition occur?

NOT ALL

The water table separates

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

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.

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

-Basements will flood. -Water from a heavy rain will not be able to sink into the ground, causing flooding. -Small depressions will be filled with water. *ALL OF THE ABOVE

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

-seeps into pores in sediment and rocks -may leak into the ground from streams -flows through fractures in bedrock *ALL OF THE ABOVE

Sinkholes typically have steep-walled sides because

NOT -of the slow flow of water through aquifers.

By what process is groundwater erosion accomplished?

NOT ALL
