Final Hydrosphere Assessment Review

Front

What is the main cause of a sudden increase of nitrates in a waterway?

Back

Runoff from a golf course can lead to a sudden increase of nitrates in a waterway due to fertilizers used on the course.

Front

What is the result of increased upwelling in a coastal area?

Back

Increased upwelling brings nutrient-rich water to the surface, resulting in more aquatic life.

Front

Where can freshwater be found?

Back

Freshwater can be found in streams, lakes, and rivers, but not in oceans.

Front

What is the main source of dissolved oxygen in the ocean?

Back

Plants and algae that live near the surface are the main source of dissolved oxygen in the ocean.

Front

How does temperature affect dissolved oxygen in a lake?

Back

As temperature increases, dissolved oxygen decreases.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, supporting marine life.

Front

What role do plants and algae play in aquatic ecosystems?

Back

Plants and algae produce oxygen through photosynthesis, which is essential for aquatic life.

Front

What is the significance of dissolved oxygen in water?

Back

Dissolved oxygen is crucial for the survival of fish and other aquatic organisms.

Front

What are nitrates and why are they important?

Back

Nitrates are compounds that provide essential nutrients for plant growth, but excessive amounts can lead to water pollution.

Front

What is the relationship between temperature and aquatic life?

Back

Temperature affects the metabolism of aquatic organisms; warmer temperatures can reduce oxygen levels, impacting life.
