(Unit 9)
This layer of the atmosphere contains the ozone layer.
What is the stratosphere? pg. 190
This occurs when two plates move apart.
What is a divergent boundary? pg. 88
This model shows population changes over time as a country develops.
What is the demographic transition model? pg. 81
This is the removal of forests and habitats for human use.
This includes all living and nonliving components interacting in an area.
What is an ecosystem? pg.44
This process traps heat in Earth’s atmosphere.
What is the greenhouse effect? pg. 192
The total amount of water that soil can hold.
What is water holding capacity? pg.90
This occurs when a population exceeds its environment’s limits.
What is a dieback? pg. 76
This irrigation system minimizes water loss by delivering water directly to roots.
What is drip irrigation? pg. 107
This biome is characterized by low precipitation, cold temperatures, and permafrost.
What is the tundra? pg. 45
This occurs when oceans absorb excess CO2.
What is ocean acidification? pg. 197
The layer of at atmosphere where climate action occurs.
What is the troposphere? pg.91
This curve shows high survival until old age.
What is a Type I survivorship curve? pg. 75
This system raises animals in high-density confined spaces.
What is a CAFO (Concentrated Animal Feeding Operation)? pg. 110
This aquatic zone receives enough sunlight for photosynthesis.
What is the photic zone? pg. 46
This atom depletes the stratosphere and was later replaced with HFCs after the Montreal Protocol.
What is Carboflourocarbons (CFCs)? pg. 191
The Earth’s main source of energy and is dependent on season and latitude.
What is Incoming solar radiation (insolation)? pg. 94
This growth pattern occurs when resources are unlimited.
What is exponential growth? pg. 77
Started a shift to newer agricultural practices and farming to increase food production.
What is the Green Revolution? pg. 105
This process removes carbon dioxide from the atmosphere and stores it in biomass.
What is photosynthesis? pg. 47
Atmospheric carbon dioxide levels rise from 320 ppm to 400 ppm. Calculate the percent increase in CO₂ concentration.
What is 25%?
Convert a land area of 5 square kilometers into square meters.
What is 5,000,000 m2?
A population increases from 2,000 to 2,600 individuals over a 2 years. Calculate the percent population growth.
What is 30%?
A farm uses 1,200 liters of water for irrigation, but 25% is lost due to inefficiency. Determine the volume of water actually used by crops.
What is 900 liters?
An ecosystem receives 8,000 J of solar energy and produces 800 J as biomass. Calculate the percent efficiency of energy conversion in this system.
What is 10%?
