What is one possible effect of building dams and reservoirs on the sediment transport in rivers?

reduction of sediment reaching downstream areas

Which human activity is most likely to cause an increase in nutrient levels in a body of water?

fertilizer runoff from nearby agriculture

elevated CO 2 levels in the atmosphere

discharging warm water from an electrical power plant

What can result from an increase in nutrient levels in a body of water?

Algae blooms that can lead to a decrease in the available O 2 for fish populations (eutrophication)

It helps remove salt from the water (desalination)

Increased O 2 levels (oxygenation)

Increased health of the fish populations

Which measure helps in controlling nonpoint source pollution?

reducing the use of chemicals and fertilizers

removing vegetation from riverbanks

preventing factory waste discharge into rivers

An area of land that drains into a particular body of water

Planting trees along riverbanks

Increasing the use of pesticides

Removing vegetation from riverbanks

Explain how human activities can negatively impact groundwater quality.

By introducing pollutants such as chemicals and waste

By increasing the amount of oxygen in the water

By reducing the amount of sunlight reaching the water

By increasing the water temperature

Which human activity is most likely to benefit surface water in a watershed?

Dumping industrial waste into rivers

Using more chemical fertilizers

Analyze the impact of deforestation on a watershed's surface water.

It increases the risk of flooding and erosion

It increases the water's oxygen levels

It reduces the amount of sediment in the water

Identify a basic concept related to groundwater in a watershed.

Groundwater is stored in underground aquifers

Groundwater is always safe to drink

Groundwater is only found in deserts

Groundwater is not affected by human activities

What is a simple procedure to protect groundwater from contamination?

Properly disposing of hazardous materials
