Honors Earth Science B Unit 7 Test: WATER as a Resource
11. All of the following are ways in which WATER & ENERGY are interdependent EXCEPT....
*
1 point
water is used to cool thermal power plants
water produces energy in hyrdroelectric dams
water requires energy when pumped and transported
water provides energy to livestock for drinking
Which of the following agricultural practices can lead to algal blooms?
*
1 point
withdrawals of water for crop irrigation
sediments released by tilling of soil
application of nutrients to crops
erosion caused by livestock overgrazing
13. Why is rainwater harvesting important in sustainable farming practices? (Choose 2)
*
2 points
It reduces the demand for using groundwater for irrigation
Allows farms to add pesticides before using
Allows water to be stored for future use
Allows water to be sanitized before applying to crops
14. Although about 70% of earth's surface is covered in water, about how much of that water is freshwater?
*
1 point
2.5%
71%
1.2%
30.1%
15. The human race is using the freshwater from our groundwater aquifers faster than it can be replaced. This overuse can result in the following:
*
1 point
the water table being lowered
the ground sinking
salt water mixing into our freshwater supply
all of the above are impacts
16. One of the biggest impacts on the water cycle by global warming is....
*
1 point
the increase in albedo or reflected light
the increased rate of evaporation
the decrease in droughts
the decrease in ocean levels
Select the reason cities tended to develop at the fall line on rivers.
*
2 points
The fall line follows the ridge of the Appalachian Mountains, providing access inland where goods could be traded.
The fall line is where rivers are no longer navigable by ships traveling in from the ocean, so goods had to be offloaded.
The fall line is the widest point along the middle of a river, so travel was easier.
The fall line is where rivers converge, which was beneficial for trade.
18. Which of the following is a major reason that many people are against damming up rivers for human use?
*
1 point
Dams create floods
Dams are not aesthetically pleasing to the community
Dams affect the aquatic organisms and surrounding ecosystem
Dams prevent the use of water for hydroelectric power
19. There are many debates over the the uses and ownership of Earth's water. Even while water may be abundant, it may be unusable in some parts of the world due to:
1 point
lack of bottles for packaging
privatization of water
lack of adequate water sanitation
lack of funds to dam rivers
20. Which use of water accounts for the highest water withdrawals in the United States?
*
1 point
mining
irrigation
thermoelectric power
industrial uses
21. Which statement describes an aquifer?
*
2 points
can be recharged after being depleted
layer of impermeable rocks
can be created only by digging or drilling
it cannot be recharged after being depleted
22. Hydraulic fracturing, or “fracking” is a controversial use of water that serves what purpose?
*
1 point
clearing land for construction
sanitizing water for farm animal consumption
damming rivers for irrigation
extracting oil and gas from underground
