The population of photosynthetic organisms is higher in the neritic zone and surface waters than in the deep ocean. Which statement best explains the reason for this?

• There is more space for plants to grow in these areas of the ocean.
• There is more dissolved oxygen for plants in these areas of the ocean.
• The availability of sunlight and nutrients supports photosynthetic organisms.
• The high salinity and cool temperature supports photosynthetic organisms.

Which statement best describes how nutrients move in the ocean as a result of upwelling?

• Nutrients move from estuaries into the intertidal zone.
• Nutrients move from warm, shallow areas to deep, colder areas.

A scientist observed that the Arctic Ocean had less dissolved oxygen in the winter as compared to the summer. What could be a reason for this?

• less salinity
• high temperatures
• an increase in upwelling
• poor phytoplankton growth

Where does salt in the oceans come from?

• Near-shore salt deposits

• River inflow

• mid-ocean ridges

• deep-sea hydrothermal vents

Answer explanation

Remember, rivers do the work of weather in and erosion on land, and they carry many dissolved ions into the ocean. When that water evaporates from the ocean, it leaves the dissolved ions behind, leaving the oceans to be salty.
