    • What is oceanic circulation driven by?
      Two main drivers
    • Steps in wind-driven circulation
      1️⃣ Wind friction on ocean surface
      2️⃣ Surface water movement
      3️⃣ Deflection by Coriolis Effect
      4️⃣ Formation of surface currents
    • Match the role in a marine ecosystem with its function:
      Producers ↔️ Create energy through photosynthesis
      Consumers ↔️ Feed on producers or other consumers
      Decomposers ↔️ Break down dead organic matter
    • Steps in thermohaline circulation
      1️⃣ Density differences due to temperature and salinity
      2️⃣ Deep water sinking
      3️⃣ Slow-moving currents form
      4️⃣ Distribution of heat and nutrients
    • Wind-driven circulation creates deep, slow-moving currents.
      False
    • What drives wind-driven circulation?
      Global wind patterns
    • In the Northern Hemisphere, which way does the Coriolis Effect deflect surface currents?
      To the right
    • What is the effect of the Coriolis Effect on wind-driven circulation in the Southern Hemisphere?
      Currents deflected to the left
    • What is the primary effect of wind patterns on oceanic circulation?
      Creates surface currents
    • Match the role in a marine ecosystem with its function:
      Producers ↔️ Photosynthesis
      Consumers ↔️ Feed on other organisms
      Decomposers ↔️ Break down dead matter
    • What role do consumers play in a marine ecosystem?
      Feed on other organisms
    • Which organisms in marine ecosystems are responsible for creating energy through photosynthesis?
      Phytoplankton and algae
    • What are examples of coastal ecosystems in marine environments?
      Coral reefs, mangroves, estuaries
    • What is an example of a deep-moving current driven by thermohaline circulation?
      Great Ocean Conveyor Belt
    • In which direction do deep currents flow in the Southern Hemisphere due to thermohaline circulation?
      Counterclockwise
    • Secondary consumers in marine ecosystems feed directly on primary producers.
      False
    • Wind-driven circulation refers to surface currents driven by global wind patterns
    • Match the type of oceanic circulation with its driver:
      Thermohaline Circulation ↔️ Density-driven by temperature and salinity
      Wind-Driven Circulation ↔️ Surface friction from wind
    • Order the steps of how the Coriolis Effect influences wind-driven circulation in the Northern Hemisphere:
      1️⃣ Earth's rotation deflects surface currents
      2️⃣ Deflection occurs to the right
      3️⃣ Large-scale circular current systems form
    • Warmer water is less dense, leading to thermohaline circulation when it rises
    • Density gradients drive thermohaline circulation, while friction between wind and ocean surfaces drives wind-driven circulation
    • Open Ocean Ecosystems are characterized by low nutrient levels
    • Coastal biomes are influenced by tides and rivers
    • Producers in marine food webs use photosynthesis to create energy
    • Decomposers recycle nutrients back into the ecosystem
    • Thermohaline circulation is caused by differences in water temperature and salinity
    • Wind-driven circulation is caused by the friction between wind and the ocean surface
    • Order the steps in thermohaline circulation:
      1️⃣ Surface water cools and becomes denser
      2️⃣ Dense water sinks to the ocean floor
      3️⃣ Deep water flows towards the equator
      4️⃣ Water warms and rises to the surface
    • Match the Coriolis Effect's influence with the hemisphere:
      Northern Hemisphere ↔️ Currents deflected to the right
      Southern Hemisphere ↔️ Currents deflected to the left
    • What role does wind-driven circulation play in shaping marine ecosystems?
      Distributes heat and nutrients
    • In the Northern Hemisphere, wind-driven circulation deflects currents to the right
    • Thermohaline circulation is density-driven, while wind-driven circulation is driven by global wind patterns
    • The Coriolis Effect is caused by the Earth's rotation.
