Ocean Quiz Part 2

What is upwelling?

• A process in which warm water rises toward the surface

• A process in which deep, cold water rises toward the surface

• A process in which surface water sinks to the ocean floor

• A process in which ocean currents change direction

Which ocean current is a well-known regional link in the ocean conveyor belt?

• The Gulf Stream

• The North Atlantic Drift

• The California Current

• The Kuroshio Current

What is El Niño-Southern Oscillation (ENSO)?

• A periodic warming of surface waters in the tropical eastern Pacific Ocean

• A process in which deep, cold water rises toward the surface

• A phenomenon that affects ocean and atmospheric circulation patterns

• A type of ocean current

What happens during El Niño?

• Trade winds weaken and warm water expands towards South America

• Trade winds strengthen and cool water expands towards South America

• Ocean currents speed up and nutrient availability increases

• Surface water temperatures in the eastern Pacific Ocean become unusually cool

What is the effect of El Niño on coastal upwelling?

• Coastal upwelling strengthens, leading to increased fish populations

• Coastal upwelling weakens, leading to reduced fish populations

• Coastal upwelling remains unaffected by El Niño

• Coastal upwelling stops completely during El Niño

What is La Niña?

• A phenomenon that occurs after El Niño

• A type of ocean current

• A process in which deep, cold water rises toward the surface

• A periodic cooling of surface waters in the tropical eastern Pacific Ocean

Which marine environment is the transition between land and ocean?

• Intertidal zone

• Benthic environment

• Pelagic environment

• Neritic zone

What is the benthic environment?

• The ocean floor from the shoreline to a depth of 200m

• The part of the pelagic environment that overlies the ocean floor at depths greater than 200m

• The area of shoreline between the low and high tides

• The part of the pelagic environment that extends from the surface to a maximum depth of 150m

What are corals?

• Soft-bodied animals that live in hard cups or shells of calcium carbonate

• Flowering plants adapted to live in sea water

• Large and complex seaweeds found in cooler temperate marine waters

• Animals that burrow in the ocean floor

What is the largest marine environment?

• Intertidal zone

• Benthic environment

• Neritic province

• Oceanic province
