Total questions: 22
Worksheet time: 12mins
How does the construction of a dam affect the groundwater levels in a watershed?
It increases groundwater levels by preventing water from flowing downstream.
It decreases groundwater levels by reducing the natural flow of water.
It has no effect on groundwater levels.
It increases groundwater levels by allowing more water to seep into the ground.
Which of the following is a direct consequence of overfishing on ocean systems?
Increased biodiversity in the ocean.
Decreased fish populations and disruption of marine food chains.
Improved water quality in the ocean.
Enhanced growth of coral reefs.
Explain how urban development can lead to harmful effects on surface water in a watershed.
Urban development increases vegetation, which improves water quality.
Urban development reduces runoff, leading to cleaner water.
Urban development increases runoff, which can carry pollutants into surface water.
Urban development has no impact on surface water quality.
What is one way humans can positively influence ocean systems?
By dumping waste into the ocean.
By establishing marine protected areas.
By increasing oil drilling activities.
By overfishing to control fish populations.
Identify a human activity that can lead to the contamination of groundwater.
Planting trees.
Using pesticides in agriculture.
Building parks.
Installing solar panels.
Discuss the impact of plastic pollution on ocean systems and suggest a strategic plan to mitigate it.
Plastic pollution has no significant impact on ocean systems.
Plastic pollution enhances marine life by providing habitats.
Plastic pollution harms marine life and ecosystems; a strategic plan could include reducing plastic use and improving waste management.
Plastic pollution is beneficial for ocean systems as it increases biodiversity.
What is the primary reason for the depletion of groundwater resources in many areas?
Excessive rainfall.
Overuse of groundwater for irrigation and industrial purposes.
Natural evaporation processes.
Increased vegetation cover.
How can the introduction of non-native species by humans affect ocean systems?
Non-native species always improve the health of ocean systems.
Non-native species can outcompete native species, disrupting the ecosystem balance.
Non-native species have no impact on ocean systems.
Non-native species increase the diversity of ocean systems without any negative effects.
Evaluate the effects of agricultural runoff on surface water quality in a watershed.
Agricultural runoff improves water quality by adding nutrients.
Agricultural runoff has no effect on water quality.
Agricultural runoff can lead to nutrient pollution, causing algal blooms and oxygen depletion.
Agricultural runoff purifies water by filtering out pollutants.
Which human activity is most likely to cause ocean acidification?
Planting trees.
Burning fossil fuels.
Building wind farms.
Using solar panels.
A city by a river is growing fast. It has more factories, houses, and farms than before.
The city council is trying to take care of the water, but they’re having a hard time.
Which statements below include harmful impacts for the water in the area? Select
THREE.
Building more houses makes hard surfaces that stop water from soaking into the
ground.
The city has tough rules for throwing away waste and treating water.
Factories let contaminated water run straight into the river.
More parks and green areas help water soak into the ground and stop runoff.
Farms use a lot of chemicals that runoff into streams.
Look at the diagram showing pollution from a waste disposal site. Select three areas of concern where pollution might spread into the water cycle.
Students are analyzing how humans affect the Blue River watershed. This watershed gives water to the nearby town of Clearwater. Recently, increased human activity has caused significant pollution of the watershed. Clearwater started two projects to better manage the watershed:
• Stream Cleanup Initiative: Volunteers and local government work together to clean up trash and other pollutants from the streams going into Blue River.
• Water Extraction Increase: Because more people and farms need water, Clearwater is now taking more water from Blue River.
During a class debate, two students, Bailey and Thomas, share different opinions:
Bailey: Cleaning the streams is good. It makes the water clean and helps nature, which is important for keeping the watershed healthy.
Thomas: Even with the cleanup, taking more water is bad. It leaves less water in the river, which can hurt wildlife.
Which student's statement is most accurate about the impact of human activities on the Blue River watershed?
Bailey
Thomas
Both
Neither
How is nonpoint source pollution different from point source pollution in a watershed?
Nonpoint source pollution comes from multiple sources, while point source pollution is from a single, identifiable source.
A marine biologist studying seabird populations notices that the number of
hatchlings declines after an oil tanker spill occurs off the coast where one of the birds’
major nesting sites is located. Which of the following is the probable human impact on
the birds’ nesting site?
Fish are tested for their heavy metal content before being sold into the food
chain supply to ensure they’re safe for human consumption. How do large fish get
heavy metal (mercury) contamination?
The fish eat the seagrass near a pollution source.
Small fish eat food containing mercury, large fish eat those small fish, and then the
toxins build in their bodies over time.
How do the industrial, agricultural and residential activities of humans most likely affect the groundwater in this area?
The activities prevent most of the water from evaporating into the atmosphere
Pollutants from the activities percolate through the soil and enter the water table.
The activities replace the groundwater used.
All of the above
Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?
The fish population will continue to rise.
A wide range in ocean temperatures will be seen worldwide.
The U.S. human population will decline.
The overfishing will cause an imbalance in marine ecosystems.
A farmer grazes 75 head of cattle in a sloped field. He fertilizes the field once a year and the cattle also leave manure in the field while grazing. Which of the following could occur in the river that the field slopes into?
Water life in the river would increase due to more grass growth in the field above.
Water life in the river would decrease due to less dissolved oxygen being in the water.
Water life would drop then adapt within two generations to the increase in nitrogen in the water.
The runoff will affect not only the water animals but eventually increase the growth in water plants clogging the waterway
This watershed diagram shows many small streams that feed into a larger creek that flows from north to south. During heavy rains, the dairy farm occasionally floods. This results in large amounts of cattle manure (feces) getting into the watershed. Which location will experience increased bacteria in the water as a consequence of this pollution?
Runoffs recharge lakes and streams.
True
False
Texas cities and towns maintain storm drains and drainage ditches to help reduce flooding of streets. Where does most of the water from the storm drains go?
Into the Gulf of Mexico
Into Local fishing ponds
Into yards of homes
Into sewage disposal plants
