Ch 3 Ocean Chemistry and Structure

Front

What is the primary source of carbon dioxide (CO2) entering the ocean?

Back

Atmosphere.

Front

True or False: Ocean temperature, salinity, dissolved gases, and density are uniform across all parts of the ocean.

Back

False.

Front

Why do large bodies of water not quickly fluctuate in temperature?

Back

Water has a high heat capacity.

Front

What process leads to insufficient calcium carbonate for marine organisms like corals and mollusks?

Back

Ocean acidification.

Front

What is the effect of increasing carbonic acid (H2CO3) on marine life?

Back

It is detrimental to shells, oysters, and corals.

Front

Define ocean acidification.

Back

The decrease in pH of the ocean due to increased carbon dioxide absorption.

Front

What role does photosynthesis play in ocean chemistry?

Back

It produces oxygen and consumes carbon dioxide, affecting pH levels.

Front

What is the significance of salinity in ocean water?

Back

It affects water density and the distribution of marine organisms.

Front

Explain the concept of heat capacity in relation to ocean water.

Back

Heat capacity is the ability of water to absorb and store heat, stabilizing ocean temperatures.

Front

What are dissolved gases, and why are they important in ocean chemistry?

Back

Dissolved gases like oxygen and carbon dioxide are crucial for marine life and chemical processes.
