All Flashcards
Define Climate.
Long-term (30+ years) weather patterns, including temperature and precipitation averages.
Define Weather.
Short-term atmospheric conditions.
Define Greenhouse Effect.
A natural process where gases in the troposphere trap thermal energy, keeping Earth warm enough to support life.
Define Greenhouse Gases (GHGs).
Gases that trap heat in the atmosphere.
Define Ocean Acidification.
The decrease in ocean pH due to the absorption of increased atmospheric CO2.
Define Disease Vector.
An organism that transmits diseases (e.g., mosquitoes, ticks).
What is Thermal Expansion?
The increase in volume of water as its temperature increases.
What is the IPCC?
The Intergovernmental Panel on Climate Change, a group of scientists assessing climate change science.
Define deforestation.
The clearing of forests for other land uses.
Define cellular respiration.
The process by which cells convert glucose and oxygen into energy, releasing carbon dioxide and water.
What are the steps of ocean acidification?
Increased atmospheric CO2, CO2 absorbed by oceans, formation of carbonic acid, lowering of ocean pH.
Describe the process of the Greenhouse Effect.
Solar radiation enters atmosphere, some radiation is reflected, some is absorbed and re-emitted as infrared radiation, GHGs trap some infrared radiation, warming the Earth.
How does thermal expansion contribute to rising sea levels?
Warmer water temperature, increased molecular motion, expansion of water volume, rise in sea level.
Describe how melting glaciers contribute to rising sea levels.
Increased global temperatures, melting of glaciers and ice sheets, increased water volume in oceans, rise in sea level.
Explain the process of CO2 emissions from fossil fuel combustion.
Extraction of fossil fuels (coal, oil, gas), burning of fossil fuels for energy, release of CO2 into the atmosphere, increased greenhouse effect.
What are the steps involved in the spread of disease vectors due to climate change?
Increased global temperatures, expansion of vector habitats, increased vector populations, increased disease transmission.
Explain the process of methane production in landfills.
Organic waste in landfills, anaerobic decomposition by bacteria, production of methane gas, release of methane into the atmosphere.
Describe the process of nitrous oxide release from agricultural fertilizers.
Application of nitrogen-based fertilizers, conversion of nitrogen by soil microbes, release of nitrous oxide into the atmosphere, increased greenhouse effect.
Explain the process of carbon sequestration in forests.
Trees absorb CO2 from atmosphere, CO2 is converted into biomass through photosynthesis, carbon is stored in trees and soil, carbon is released when trees decompose or burn.
Describe the process of climate change impact on biodiversity.
Changes in temperature and precipitation patterns, habitat alteration and loss, species displacement or extinction, disruption of ecosystems and food chains.

What is a disease vector?
An organism that transmits diseases (e.g., mosquitoes, ticks).
What is thermal expansion?
The increase in volume of a substance (like water) due to an increase in its temperature.
Define IPCC.
Intergovernmental Panel on Climate Change: A group of scientists assessing climate change science, impacts, and risks.
Define deforestation.
The clearing of forests for other land uses.
Define cellular respiration.
The process by which cells break down glucose to release energy, producing carbon dioxide and water as byproducts.
