If a body of water has high turbidity levels, what can MOST likely be concluded?

• It has a low pH

• It is unsafe to drink

• It is too hot to drink

• It contains a lot of chemicals.

If water is recycled in the atmosphere, which BEST describes why water availability on Earth is decreasing?

• An increase in droughts is slowly reducing freshwater reservoirs.

• Due to an increase in Earth's temperature, evaporation rates continue to increase reducing liquid water on the surface.

• Earth's freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.

• We are taking too much of it to Mars to see if we can colonize there.

Which would MOST affect the health of fish in a local pond?

• The daily release of hot water into the pond from a local factory

• A storm temporarily stirring up water and sediments in the pond

• The occasional erosion of sediments into the pond from a nearby field

Why does fertilizer pollution stimulate the growth of algae in a pond?

• Algae are producers and use the fertilizer's nutrients to rapidly multiply.

• Algae are producers and use the fertilizer's nutrients during decomposition.

• Algae are parasites and absorb energy from the fertilizers in order to grow.

• Algae are herbivores that feed off of the plants, which grow due to excess fertilizers.
