Water is most dense at what temperature in degrees Celsius?

• 32
• 4
• 0
• -4

What is the main reason that runoff is a water quality issue?

• because it happens after a rainfall
• because it removes water from the atmosphere
• because it increases the amount of water in streams
• because it can carry nitrates and other pollutants into bodies of water

Why is turbidity, cloudiness, an important factor in water quality?

• because underwater plants need light for photosynthesis
• because fish need to be able to breathe
• because coral are sensitive to temperature increases
• because nitrates can cause algal blooms
