All Flashcards
What are the effects of ozone depletion?
Increased UV radiation, skin cancer, cataracts.
What are the consequences of increased greenhouse gases?
Global warming, climate change, sea level rise.
What are the impacts of ocean acidification?
Shellfish decline, coral bleaching, food web disruption.
What are the effects of habitat destruction?
Biodiversity loss, species extinction, ecosystem disruption.
What are the consequences of invasive species?
Ecosystem imbalance, competition with native species, economic damage.
What is the impact of overexploitation?
Depletion of resources, endangerment of species, ecosystem collapse.
Steps of ozone depletion?
CFCs released, reach stratosphere, UV breaks CFCs, chlorine released, chlorine destroys ozone.
Steps of ocean acidification?
Atmospheric CO2 increases, ocean absorbs CO2, carbonic acid forms, pH decreases.
How does the greenhouse effect work?
Solar radiation enters, Earth absorbs/radiates heat, greenhouse gases trap heat, Earth warms.
Define Stratosphere.
Atmospheric layer above the troposphere, containing the ozone layer.
Define Ozone Layer.
Region in the stratosphere with high ozone (O3) concentration, absorbing harmful UV radiation.
Define Chlorofluorocarbons (CFCs).
Stable compounds used in refrigerants and propellants that deplete the ozone layer.
Define Global Warming Potential (GWP).
Measure of how much heat a gas traps in the atmosphere compared to CO2.
Define Ocean Acidification.
Decrease in ocean pH due to increased absorption of atmospheric CO2.
Define Specialist Species.
Species with a narrow niche, vulnerable to environmental changes.
Define Generalist Species.
Species with a broad niche, adaptable to various environments.
Define K-selected Species.
Species with low reproductive rates and long lifespans.
Define r-selected Species.
Species with high reproductive rates and short lifespans.
Define Invasive Species.
Non-native species that disrupt ecosystems.
