Question 1
Question 2

 Since I have it from last year, so far this semester we have discussed...
Unit 1 - Introduction to Environmental Science and Sustainability (a not quite exhaustive list - feel free to comment and add)
  • Environmental science
    • definition
    • problems that ES is concerned with
    • causes of those problems
  • Environmentalism vs. ecology
  • Sustainability
    • definition
    • ways of measuring sustainability/environmental impact (IPAT equation)
    • 4 principles of sustainable environments/sustainability
  • Ecological footprint
Unit 2 - Earth Systems and Resources
  • Composition of Earth
  • Composition of Earth’s atmosphere
    • Climate and weather
    • Greenhouse effect
    • Coriolis effect
    • Convection
  • Requirements for life on Earth
    • Extinction and history of life on Earth
    • Origins of oxgyen
  • Plate tectonics and consequences
    • Volcanism
    • Plate boundaries
    • Earthquakes
  • Rocks
    • Types and characteristics
  • Soil
    • Composition of soils
    • Soil horizons
    • Conservation techniques
  • Carbon cycle
Unit 3 - Ecology
  • Food webs
    • Consequences of changes in a food web
    • Trophic levels
      • Eating lower on the food chain
    • Biomass
    • Energy pyramids
  • Nitrogen cycle
    • Nitrification, nitrogen fixing, denitrification
    • Eutrophication
  • Phosphorus cycle
  • Biomes
    • Characteristics
    • Example species
  • Niches and competition
    • Symbiosis, parasitism, commensalism, mutualism
  • Photosynthesis and respiration
  • Invasive species
  • Succession - primary and secondary
  • Definitions
    • Population, community, etc.
  • Evolution - requirements, evolution, consequences
Unit 4 - Populations
  • Logistic growth
  • Carrying capacity
    • Density-dependent and density-independent factors limiting population growth
  • Age-structure diagrams
  • Demographic transition
  • Factors affecting birth/death rates
  • Population growth predictions
  • Malthus’ predictions
    • Geometric and arithmetic growth
  • Calculating annual rate of population change
  • Calculating doubling time
  • r-strategists and K-strategists
  • Intrinsic growth rates
Unit 5 - Land and Water Use

  • Agriculture
  • State of global nutrition
  • Feedlot agriculture
    • CAFOs
  • Irrigation
    • Consequences - salinization, runoff
    • Sustainable practices - terracing, contour farming
  • Fertilizing crops/Green Revolution
    • Consequences - runoff
    • Sustainable practices - no-till agriculture, crop rotation, intercropping, strip cropping
  • Genetic engineering
  • Pest control
    • Pesticides and consequences - runoff, resistance
  • Sustainable practices - IPM
  • Fishing - methods and consequences
    • Purse-seine, trawling, hook and line, deep line, drift net, dredging, pot/traps, dynamite/cyanide
  • Aquaculture
  • Water supply - freshwater v. saltwater
  • Water usage
Jeopardy - with school being cancelled today, we have less time to review and taking the time to play Jeopardy makes less sense. But, you can see the questions and associated answers in the links below.
