Of the 74% of Earth’s surface that is covered in water, which contains the most water?

• lakes

• rivers

• oceans

• streams

The figure shows the zones of the ocean. Coral reefs require sunlight because reef-building coral contain photosynthetic algae in their tissues. The reefs must sit on the ocean floor for support and must remain underwater to survive. In which ocean zone does a reef most likely thrive?

• oceanic zone

• benthic zone

• neritic zone

• intertidal zone

What is the movement of cold, nutrient-rich waters from the bottom of the ocean, promoting algae growth?

• upwelling

• deposition

• precipitation

• eutrophication

The EPA (Environmental Protection Agency) regulates the level of turbidity in drinking water to protect public health. The EPA sets the limit at 0.3 NTU (Nephelometric Turbidity Units). The data shows the turbidity level of four samples taken from the same location over four consecutive days. Based on the data, which best explains the quality of the drinking water?

• The drinking water is safe because the first two samples are below the recommended limit

• The drinking water is unsafe because the last two samples are above the recommended limit

• The drinking water is unsafe because the last two samples are below the recommended limit

• The drinking water is safe because the average of the samples is below the recommended limit

Which does an increase in eutrophication indicate to scientists studying a body of water?

• an increase in fertilizer runoff

• a decrease in pollutants from farm runoff

• an increase in the health of the body of water

• an increase in oxygen levels in the body of water

How are indicator species like a warning system for bodies of water?

• They indicate when food sources are declining

• Their illness or death indicates pollution in an aquatic ecosystem

• They indicate when predators are reducing the numbers of a species

• Their illness or death indicates the body of water is becoming more populated
