Ocean Warming and Coral Reefs

The video discusses ocean warming, its causes, and effects on marine life and ecosystems. It explains the two-way relationship between atmospheric and oceanic warming, highlighting the ocean's role in absorbing heat due to its high specific heat. The video also covers the impact of warming on marine organisms, such as reduced oxygen levels and altered migratory patterns. It further explores the effects of climate change on coral reefs, including coral bleaching caused by temperature changes and pollution.

What is the primary cause of ocean warming?

• Increased volcanic activity

• Greenhouse gases trapping heat

• Decreased solar radiation

• Increased ocean salinity

How does water's high specific heat affect ocean warming?

• It prevents the ocean from absorbing heat

• It allows the ocean to absorb and store large amounts of heat

• It causes the ocean to release heat quickly

• It makes the ocean temperature fluctuate rapidly

Why is warmer water a concern for marine species like fish and whales?

• Warmer water holds more oxygen

• Warmer water decreases salinity

• Warmer water increases food availability

• Warmer water holds less oxygen

How can ocean warming affect the migratory patterns of marine species?

• It causes species to migrate later in the season

• It can alter the timing and routes of migration

• It makes species migrate to colder regions

• It has no effect on migratory patterns

What is a potential consequence of algae blooms in warmer waters?

• Increased oxygen levels

• Blocked sunlight and reduced aquatic plant growth

• Enhanced coral growth

• Decreased water temperature

What is one effect of climate change on coral reef ecosystems?

• Thermal stress leading to coral bleaching

• Increased coral growth

• Decreased sedimentation

• Reduced storm frequency

How can changes in storm patterns affect coral reefs?

• They can increase coral growth

• They reduce nutrient availability

• They can cause physical damage to reefs

• They have no impact on coral reefs

What is the primary cause of coral bleaching?

• Increased salinity

• Pollutants from land

• Loss of symbiotic algae due to temperature changes

• Excessive sunlight

What role do zooxanthellae play in coral reefs?

• They protect coral from predators

• They provide structural support

• They supply energy through photosynthesis

• They increase water salinity

What happens to coral when it becomes bleached?

• It dies immediately

• It becomes more resilient

• It loses its main energy source and becomes vulnerable

• It gains new algae
