Ozone Depletion
Stratosphere
What layer of the atmosphere does global warming occur in?
Troposphere
Coral bleaching is most directly linked to what phenomena?
Ocean Warming
Name one reason why species become endangered and/or extinct?
Name one of the human threats to biodiversity found in HIPPCO
Habitat fragmentation, Invasive species, Population Growth, Pollution, Climate Change, Over Exploitation
The ozone layer is important for all survival on earth because it has the ability to block 97-99% of this type of light ray from reaching the surface of the earth.
UV (UV-B and UV-C)
Methane has a higher or lower global warming potential than CFCs
Lower
The heat that is transferred into the ocean comes from...
What reproductive strategy is best suited to be an invasive species?
r-selected
What is an environmental effect of climate change?
rising temperatures (atmospheric or ocean), rising sea levels, melting permafrost etc
What is the only anthropogenic greenhouse gas?
CFCs
What region(s) of the earth are warming faster than any other region?
Polar regions (polar amplification)
Thermal Expansion
In general, what is the best long-term method of preventing extinction?
Protecting the habitats of endangered species
What type of feedback loop results when Arctic ice melts -> sea levels rise -> more ice melts...
positive feedback loop
What do scientists consider the main cause of ozone depletion?
Aerosols (CFCs)
Ozone, O3
What is an anthropogenic cause for ocean acidification?
Fossil fuel combustion (CO2), deforestation (CO2), and coal/gas combustion (NOx/SOx → acid precip.)
Invasive species tend to be so successful because they are highly competitive, can thrive in non-native environments, and they often lack this in their new environment ....
No natural predators
What piece of legislation was a GLOBAL agreement to phase CFCs out of production in refrigerators, aerosols and other products
Montreal Protocol
What specific atom persists in the stratosphere that will destroy up to 100,000 ozone molecules
Cl- Chlorine (from CFCs)
What is an important contributor to both global warming and ozone depletion?
CFCs
Less of ___________ ions = less calcification; weaker shells of coral, mollusks, and urchins
Carbonate
Which international agreement led to the US passing the Endangered Species Act and all other involved countries to set up agencies to monitor movements of endangered species?
Which greenhouse gas is responsible for ocean acidification?
CO2- Carbon Dioxide
Increased CO2 in atmosphere ➡️ increased ocean CO2 (direct exchange)
CO2 combines with ocean water to form carbonic acid (H2CO3) --> Carbonic acid dissociates into Bicarbonate ion (HCO3-) and H+ ion
