Atmosphere + Greenhouse Gases
Which atmospheric layer does the Greenhouse effect primarily occur in?
Troposphere
Rising levels of this greenhouse gas are a primary driver of ocean warming and acidification.
Carbon Dioxide
This human activity causes habitat fragmentation and is a major threat to biodiversity worldwide.
Deforestation
This greenhouse gas, produced by livestock and landfills, accelerates climate change and has a shorter lifespan than CO2
Methane
This type of ecosystem is home to many species and is dying off due to ocean acidification and rising temperatures.
Coral reefs
The extinction of a single species can trigger a chain reaction, affecting others in the food web, a process known by this term.
Trophic Cascade
2pt
This protocol ( ) began phasing out ( ) to help prevent ozone depletion.
Montreal Protocol
Refrigerants/DDS
What impact does climate change have on polar regions and how does it effect the rest of the world?
-melting of ice and permafrost (Polar)
-altered weather patterns, rising sea levels, and potential economic and social consequences
What characteristics tend to increase the risk of a species becoming endangered?
-Having a very limited distribution
-Being a specialist at the end of a long food chain
-Having a small population size
How does ozone depletion affect the environment? Expand, how does your answer affect humans?
Increased UV radiation reaching Earth's surface
(Expand) Multiple answers, none specific.
Warming of oceans are altering the distribution of marine species. Explain why some fish populations are moving toward the poles and what potential impacts this has on ecosystems or fisheries.
As ocean temperatures rise, many fish species migrate toward cooler, deeper, or more polar waters to stay within their optimal temperature range (range of tolerance). This shift can disrupt local ecosystems, harm fisheries that rely on stable populations, and lead to conflict over fishing rights in new regions.
What kind of species plays a critical role in maintaining the structure of an ecosystem. And give an example of one.
(Keystone Species)
-Sea Otters
-Beavers
-Wolves, etc.
