Front

What is a spring tide?

Back

A spring tide is characterized by really high tides that occur when the gravitational forces of the moon and sun align, resulting in higher than normal tidal ranges.

Front

What is upwelling in oceanography?

Back

Upwelling is the movement of deep, cold, nutrient-filled water to the surface of the ocean, which supports marine life and ecosystems.

Front

What factors affect the density of water?

Back

The density of water is affected by temperature and salinity.

Front

How does temperature affect water density?

Back

As temperature increases, water density decreases; colder water is denser than warmer water.

Front

How does salinity affect water density?

Back

Higher salinity increases water density, as dissolved salts add mass to the water.

Front

What is the relationship between salinity and temperature in deep ocean currents?

Back

Salinity and temperature together determine the density of water, which drives deep ocean currents.

Front

What are the two main types of tides?

Back

The two main types of tides are spring tides and neap tides.

Front

What is a neap tide?

Back

A neap tide occurs when the gravitational forces of the moon and sun are perpendicular to each other, resulting in lower than normal tidal ranges.

Front

What role does upwelling play in marine ecosystems?

Back

Upwelling brings nutrient-rich water to the surface, supporting phytoplankton growth and, consequently, the entire marine food web.

Front

What is the significance of ocean currents?

Back

Ocean currents regulate climate, distribute heat, and influence weather patterns globally.
