Multiple choice

What is the significance of the specific heat of seawater in ocean dynamics?

  1. It affects ocean currents.

  2. It influences the formation of waves.

  3. It determines the ocean's heat capacity.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The specific heat of seawater plays a crucial role in ocean dynamics by influencing ocean currents, wave formation, and the ocean's overall heat capacity.

Multiple choice

Which factor primarily influences the specific heat of seawater?

  1. Salinity

  2. Temperature

  3. Pressure

  4. Dissolved gases
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Salinity, or the amount of dissolved salts in seawater, is the primary factor influencing its specific heat.

Multiple choice

How does salinity affect the specific heat of seawater?

  1. It increases the specific heat.

  2. It decreases the specific heat.

  3. It has no effect on the specific heat.

  4. The effect varies depending on the temperature.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Salinity increases the specific heat of seawater because dissolved salts require more energy to raise their temperature.

Multiple choice

What is the relationship between the specific heat of seawater and ocean currents?

  1. Higher specific heat leads to stronger currents.

  2. Lower specific heat leads to weaker currents.

  3. Specific heat has no influence on ocean currents.

  4. The relationship varies depending on the latitude.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Higher specific heat allows seawater to store more heat, which can drive stronger ocean currents.

Multiple choice

What is the primary source of acidity in seawater?

  1. Carbon dioxide

  2. Sulfuric acid

  3. Nitric acid

  4. Hydrochloric acid
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon dioxide dissolves in seawater and forms carbonic acid, which is a weak acid that contributes to the acidity of seawater.

Multiple choice

What is the primary source of calcium carbonate in seawater?

  1. Coral reefs

  2. Mollusk shells

  3. Foraminifera tests

  4. Coccolithophores
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Coccolithophores are a type of phytoplankton that produce calcium carbonate shells, which are a major source of calcium carbonate in seawater.
