What is the mechanism by which deep water in the Earth's interior is brought to the surface?

Back

Volcanoes are the mechanism by which deep water in the Earth's interior is brought to the surface.

Front

What process brings nutrients closer to the ocean's surface?

Front

What happens when organisms die and their solid parts drift to the bottom of the ocean?

Back

They add salts to the seawater.

Front

Define 'salinity' in the context of oceanography.

Back

Salinity refers to the concentration of dissolved salts in seawater.

Front

What is 'upwelling' and why is it important for marine ecosystems?

Back

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

Front

Explain the role of volcanoes in Earth's systems.

Front

What is the difference between upwelling and downwelling?

Back

Upwelling is the movement of water from the depths to the surface, while downwelling is the movement of surface water down into the ocean.

Front

How does the death of marine organisms affect seawater composition?

Back

The death of marine organisms adds organic matter and salts to the seawater.
