Upwelling, Currents, Gasses, and Ocean Resources

Front

What produces most of our Earth's Oxygen?

Back

Phytoplankton are responsible for producing most of Earth's oxygen through photosynthesis.

Front

How have carbon dioxide levels in the air changed throughout Earth's history?

Back

The difference today is how rapidly the change is happening.

Front

What begins the process of ocean acidification?

Back

Ocean acidification begins with carbon dioxide released from combustion.

Front

Are upwellings areas of rich biological diversity?

Back

True, upwellings are areas of rich biological diversity.

Front

What do ocean currents bring from the equator?

Back

Ocean currents bring warm water from the equator towards the Poles.

Front

Define upwelling.

Back

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

Front

What role do phytoplankton play in the ocean ecosystem?

Back

Phytoplankton are primary producers that form the base of the ocean food web and produce oxygen.

Front

What is the impact of increased carbon dioxide in the atmosphere?

Back

Increased carbon dioxide leads to global warming and ocean acidification.

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of water within the oceans, driven by wind, temperature, and salinity differences.

Front

What is the significance of ocean resources?

Back

Ocean resources provide food, energy, and raw materials, and are vital for economic activities.
