Questions and Answers

What primarily influences the flow of surface currents in the oceans?

  • Ocean floor topography
  • Wind, Earth rotation, and shape of continents (correct)
  • Moon phases
  • Temperature variations and atmospheric pressure

What effect does the Earth's rotation have on ocean currents?

  • It increases the temperature of ocean water.
  • It has no effect on currents.
  • It alters the direction of winds and currents. (correct)
  • It creates a stronger current in the Southern Hemisphere.

How does salinity affect deep water currents?

  • Higher salinity decreases water density.
  • Salinity variations do not affect density.
  • Higher salinity increases water density. (correct)
  • Freshwater increases water density.

Surface Currents

Movement of water in the upper 100-200 meters of the ocean.

Deep Currents

Movement of water below 200 meters.

Wind

The force that causes air to move due to uneven heating.
