Ocean Life and Climate Change

The video discusses how ocean temperatures are stable but still affected by climate change, impacting marine life like the threeline mud snail. Research shows these snails are migrating to warmer waters due to earlier spawning triggered by rising temperatures, leading to a feedback loop that threatens their survival. This phenomenon may affect other bottom-dwelling species globally. The video also promotes Brilliant's interactive courses.

What characteristic of ocean water affects temperature stability compared to air?

• Ocean water holds onto heat better than air.

• Ocean water is denser than air.

• Ocean water is more transparent than air.

• Ocean water is saltier than air.

Why are marine organisms particularly vulnerable to rising temperatures?

• They are adapted to a narrow temperature range.

• They thrive in warmer waters.

• They can easily migrate to cooler areas.

• They have a wide temperature tolerance.

What triggers the spawning of the threeline mud snail?

• Longer daylight hours.

• Warmer water temperatures.

• The availability of food.

• The presence of predators.

Where do threeline mud snail larvae typically grow and settle?

• In shallow waters near the shore.

• In freshwater rivers.

• In deeper, cooler waters at the continental shelf edge.

• On the ocean surface.

What unexpected trend did researchers find in the threeline mud snail populations?

• They were migrating northward.

• They were missing from deeper waters.

• They were thriving in deeper waters.

• They were unaffected by climate change.

What is the main reason for the wrong-way migration of the threeline mud snail?

• Their choice to move to warmer waters.

• Their inability to travel long distances.

• Their physiology being influenced by ocean physics.

• Their preference for shallow waters.

How do springtime ocean currents affect the threeline mud snail larvae?

• They disperse them evenly across the ocean.

• They funnel them towards the shore.

• They keep them stationary.

• They push them towards deeper waters.

What is the potential consequence of the wrong-way migration for the threeline mud snail?

• Adaptation to warmer temperatures.

• Migration to other oceans.

• Increased population growth.

• A feedback loop leading to earlier spawning.

What percentage of bottom-dwelling species have disappeared from the North Atlantic since the 1960s?

• 70%

• 50%

• 80%

• 60%
