Stratospheric Ozone Depletion
Ozone in the stratosphere absorbs this
What is UV radiation? Specifically UV-B and UV-C.
This type of radiation is absorbed by greenhouse gases, resulting in the warming of Earth
What is infrared (IR) radiation?
Climate change is causing an increase in these two things (need both!)
What are temperature and sea level?
As temperature increases, the amount of O2 water can hold _____
What is decreases?
Invasive species tend to have these two characteristics
What are R-Selected & Generalists
The presence of the ozone layers prevents these two major health problems
What are skin cancer and cataracts?
Name two greenhouse gases.
What is water vapor, ozone, methane, carbon dioxide, nitrous oxides
What GHG does the melting of permafrost release?
What is methane?
This is causing the increase in CO2 levels in the oceans
What is the increase of atmospheric CO2 by humans?
Name one practice that can lower genetic diversity.
Monocropping, GMOs, selective breeding, bottlenecking
This class of anthropogenic gases have the highest known GWP levels
What are fluorinated gases?
This GHG is produced at landfills
What is methane?
Chemical that can be used for cooling refrigerators and air conditioners.
CFCs
This causes coral bleaching
What is an increase in ocean temperatures?
Name a cause of natural endangerment
Starvation
Being outcompeted by other similar species
Excessive predation
Natural disaster
Loss of habitat through natural means
Impediments to mating
Natural ozone depletion is caused by this
What is the formation of clouds in the Antarctic?
Accept: Spring melting, which aids in the formation of those clouds; ice crystals that degrade ozone
Name one source of greenhouse gases stemming from agricultural practices.
What are over-irrigation, fertilizer use, and raising livestock?
This portion of the world is warming most rapidly.
What are the poles?
Describe how the pH of the ocean is changing
The pH of the ocean is decreasing - it is becoming more acidic due to CO2 causing an increase in carbonic acid
To protect endangered species, this human activity is often criminalized
What is poaching?
Why are CFCs so potent?
They continue to break up ozone molecules until out of the atmosphere.
(1 CFC can break up many ozone molecules)
Decaying organic matter typically converts into this GHG. However, under conditions lacking O2, it converts into this GHG instead.
What are Carbon Dioxide and Methane?
Why does loss of ice and snow cause a positive feedback loop of warming at the poles? b
loss of ice and snow (high albedo) decreases reflection of sunlight away, resulting in land / ocean exposure (low albedo) causing an increase in heat absorption
Ocean acidification decreases the amount of this substance in the oceans, which is vital for living creatures that form shells
What are carbonate ions?
This law authorizes the USFSW to determine which species can be listed as threatened or endangered
What is the Endangered Species Act?
