Humans and the Hydrosphere

Fertilizer runoff can cause too much nitrogen and other chemicals to enter rivers and lakes. Too much nitrogen in the water can cause which of the following?

• Increased fish populations in lakes.

• Improved water clarity and quality.

• Enhanced growth of aquatic plants.

• Algal blooms and oxygen depletion in water bodies.

Answer explanation

Too much nitrogen in water leads to algal blooms, which can deplete oxygen levels, harming aquatic life. This is the primary consequence of fertilizer runoff, making 'Algal blooms and oxygen depletion in water bodies' the correct answer.

How does the ocean contribute to the air we breathe?

• Marine animals produce oxygen through respiration.

• The ocean absorbs carbon dioxide, reducing air quality.

• The ocean contributes to the air we breathe by producing oxygen through photosynthesis by marine plants.

• The ocean has no impact on the air we breathe.

How do ocean currents impact global weather patterns?

• Ocean currents are solely responsible for earthquakes.

• Ocean currents only affect marine life, not weather.

• Ocean currents have no effect on weather patterns.

• Ocean currents significantly impact global weather patterns by moving warm water from the equator to the poles.
