Aquatic Science

How would climate be impacted if there were no surface ocean currents?

• Climate would not be impacted

• The hot regions would be less hot, the cold regions would be less cold

• The hot regions would be more hot, the cold regions would be more cold

Why do large bodies of water, like lakes and oceans, not quickly fluctuate in temperature?

• Because water is a versatile solvent.

• Because water is an acid.

• Due to water’s high specific heat.

• Because water acts as a buffer.

What term describes when water is attracted to other substances?

• Capillary action.

• Adhesion.

• Cohesion.

• Surface tension.

pH is a scale that measures acidity and alkalinity. The scale goes from 1 to

• 30

• 1,000,000

• 18

• 14

Ocean Bay food chains are complex. Sea otters eat sea urchins which eat kelp. If sea otters are removed from the food chain, what will happen to the rest of the food chain?

• The sea urchins will become over populated and consume all the kelp forests

• The sea urchin populations will decrease allowing an increase in kelp forests

• Sea otters have no impact on sea urchin populations

• Kelp forests will out compete the sea urchins for resources

Think about what you have learned about tidal zones. Which is the best explanation as to why animals living in intertidal zones must have unique adaptations

• Animals in this area must survive living long periods of time with and without water

• Animals in this area must adapt to constant shark and dolphin predators

• These areas are common for boats to dock, animals have adapted to the human intrusion

• Animals in the tidal zones must be very large to withstand the constant smashing of the waves against them

Modern plastic waste (aka microplastics) ________________________________.

• are all recycled to prevent ocean contamination

• are a biodegradable product that will eventually degrade if they end up in the ocean

• can provide nutrition for aquatic organisms

• never completely goes away, but ends up as tiny pieces in the oceans foodweb

• Oil Spills

• Coral reef death

• Noise pollution
