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

*
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.

*
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:

water provides energy to livestock for drinking
11. water provides energy to livestock for drinking
15. all of the above are impacts
16. the increased rate of evaporation
Select the reason cities tended to develop at the fall line on rivers:
- 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.
18. Dams affect the aquatic organisms and surrounding ecosystem
19. lack of adequate water sanitation
20. irrigation
21. can be recharged after being depleted, layer of impermeable rocks
22. extracting oil and gas from underground
To answer these questions, let's break down each question and explain how to arrive at the correct answer.
11. All of the following are ways in which WATER & ENERGY are interdependent EXCEPT....
To answer this question, you need to determine which option does not represent an interdependence between water and energy. Look at each option and check if it involves a relationship between water and energy. The correct answer is "water provides energy to livestock for drinking" because it does not involve a direct interdependence between water and energy.
Which of the following agricultural practices can lead to algal blooms?
To answer this question, you need to identify which agricultural practice can contribute to the occurrence of algal blooms. Look at each option and determine if it is related to algal blooms. The correct answer is "application of nutrients to crops" because excessive nutrient runoff from agriculture can stimulate algal growth.
13. Why is rainwater harvesting important in sustainable farming practices? (Choose 2)
To answer this question, you need to select two options that explain the importance of rainwater harvesting in sustainable farming practices. Look at each option and consider if it is a benefit of rainwater harvesting in sustainable farming. The correct answers are "it reduces the demand for using groundwater for irrigation" and "allows water to be stored for future use" because they both highlight the benefits of rainwater harvesting in sustainable farming.
14. Although about 70% of earth's surface is covered in water, about how much of that water is freshwater?
To answer this question, you need to estimate the percentage of Earth's surface water that is freshwater. Evaluate the options and select the one that best represents the estimated percentage. The correct answer is "2.5%" because it is the closest estimate to the actual percentage of freshwater on Earth.
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:
To answer this question, you need to identify the impacts of overusing groundwater from aquifers. Evaluate the options and select the one that best represents the impacts of overuse. The correct answer is "all of the above are impacts" because all three options ("the water table being lowered," "the ground sinking," and "salt water mixing into our freshwater supply") are possible impacts of overuse.
16. One of the biggest impacts on the water cycle by global warming is....
To answer this question, you need to identify the biggest impact of global warming on the water cycle. Evaluate the options and select the one that represents the most significant impact. The correct answer is "the increased rate of evaporation" because global warming can increase evaporation rates and alter the water cycle.
Select the reason cities tended to develop at the fall line on rivers.
To answer this question, you need to identify the reason why cities developed at the fall line on rivers. Evaluate the options and select the one that explains the historical trend. The correct answer is "The fall line follows the ridge of the Appalachian Mountains, providing access inland where goods could be traded."
18. Which of the following is a major reason that many people are against damming up rivers for human use?
To answer this question, you need to identify a major reason why some people oppose damming rivers for human use. Evaluate the options and select the one that represents a significant concern. The correct answer is "Dams affect the aquatic organisms and surrounding ecosystem" because damming rivers can disrupt ecosystems and harm aquatic organisms.
19. There are many debates over 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:
To answer this question, you need to identify the factors that can make water unusable in certain parts of the world, despite its abundance. Evaluate the options and select the one that best represents the obstacle. The correct answer is "lack of adequate water sanitation" because poor water sanitation can render abundant water sources unusable.
20. Which use of water accounts for the highest water withdrawals in the United States?
To answer this question, you need to identify the use of water that involves the highest water withdrawals in the United States. Evaluate the options and select the one that best represents the major water user. The correct answer is "irrigation" because agriculture accounts for the largest water withdrawals in the United States.
21. Which statement describes an aquifer?
To answer this question, you need to identify the statement that describes an aquifer. Evaluate the options and select the one that best represents the definition of an aquifer. The correct answer is "can be recharged after being depleted" because aquifers can be replenished with water over time.
22. Hydraulic fracturing, or “fracking” is a controversial use of water that serves what purpose?
To answer this question, you need to identify the purpose of hydraulic fracturing or "fracking." Evaluate the options and select the one that represents the intended use of water in fracking. The correct answer is "extracting oil and gas from underground" because fracking involves the high-pressure injection of water to extract fossil fuels.
