A coastal engineer is investigating the impact of ocean currents on a barrier island that is shrinking over time. Which of the following could explain the changes to the island? (Select TWO)

• Increased wave action is eroding the sand

• The island is located near a divergent plate boundary

• Longshore currents are transporting sand away from the island

• The salinity of the ocean is increasing due to global warming

The Gulf Stream carries warm water from the Gulf of Mexico toward Western Europe. Scientists have found that areas near this current tend to have milder climates than other places at similar latitudes. Which of the following best explains how ocean currents, geologic features, and climate are connected in this example?

• The Gulf Stream cools regions by bringing deep ocean water to the surface.

• The Gulf Stream’s path is shaped by continental margins and helps warm nearby climates.

• The Gulf Stream weakens due to underwater volcanoes near island atolls.

• The Gulf Stream forms new geologic features as it travels across the ocean.

Which of the following best describes the process of osmosis?

• The movement of solutes from a region of high concentration to low concentration

• The movement of solutes across a semipermeable membrane from low solute concentration to high solute concentration

• The movement of water molecules across a semipermeable membrane from high solute concentration to low solute concentration

• The movement of water molecules across a semipermeable membrane from low solute concentration to high solute concentration

How does the salinity of ocean water affect its density?

• Higher salinity decreases density

• Salinity only affects temperature

• Higher salinity increases density

• Salinity has no effect on density

Which factor is most responsible for the formation of deep ocean currents?

• Surface winds

• Temperature and salinity differences

• Earth's rotation

• Solar radiation
