How does transparency benefit photosynthetic organisms?

• It decreases the salinity of seawater.
• It allows them to see prey and predators.
• It allows them to create carbon dioxide.
• It allows them to create their own food.

What happens to the pressure of water as you go deeper into the ocean?

• Increases
• Decreases
• Stays the same
• Only fluctuates with temperature.

Why does sound travel faster in water than in air?

• Water is more dense than air.
• Water is less dense than air.
• Water is usually a lower temperature than air.
• Water is usually a higher temperature than air.

Why is water considered to be a universal solvent?

• It can dissolve the most things of any natural substance.
• It can be dissolved by almost any substance.
• It easily bonds to other elements during chemical reactions.
• It can easily change to the three states of matter.

\Salinity is measured in parts per ____________________.

• thousand
• hundred
• ten
• ten thousand

As the temperature of seawater decreases (decreases, increases), it’s density increases (decreases, increases).

• decreases, increases
• increases, increases
• decreases, decreases
• increases, decreases
