Global Warming
what is global warming?
the increase in the planet's overall average temperature
what is coral bleaching?
when coral loses its color into white and Zooxanthellae is lost
what's Ms. Rivera's favorite shark
mako shark
what is ocean acidification?
the ongoing decrease in the pH of the Earth's oceans, primarily caused by the absorption of excess carbon dioxide (CO2) from the atmosphere, leading to a rise in acidity and impacting marine life
How many reflective surfaces do ice caps provide?
2
human impacts on global warming?
oil industry
sewage disposal
burning fossil fuel
deforestation
what causes coral bleaching?
rise in water temperature
what date is paper 3&4
may 5th and 8th
what is PH?
measure of how acidic/basic water is
Sudden increase in freshwater in the oceans affects what type of organisms?
Stenohaline
what are natural impacts on global warming?
Volcanic Activity
Changes in the Earth's Orbit and Rotation
Variations in Solar Activity
what is the purpose of the zooxanthellaei in coral?
provide food and oxygen through photosynthesis
what's the most potent greenhouse gas
methane
how does ocean acidification affect marine life?
harm life forms that rely on carbonate-based shells and skeletons, harm organisms sensitive to acidity and harm organisms higher up the food chain that feed on these sensitive organisms
With the named examples, what animas depend on ice sheets for habitat & hunting grounds?
Polar bears and walruses
what is enhanced greenhouse effect and the reactants?
the increased concentration of greenhouse gases in the atmosphere, reactants are carbon dioxide methane and nitrous oxides
what temperature does coral bleaching occur?
87 degrees or above for coral bleaching
what animal benefits from global warming
jellyfish
how much more is acidic is the PH levels since the 18th century?
30%
What problems do rising sea levels create?
encroaching of costal habitats and human development.
what zones does global warming affect?
global warming affects all zones
what nutrient is lost in coral bleaching?
carbohydrates, lipids, amino acids, sugars
how do mangroves help with global warming
they are carbon sinks
what do water and co2 react to make
carbonic acid
how do ice caps affect the global conveyor belt?
without the ice caps the global conveyor belt will stop due to it being driven by the cold water
