Study Notes
Environmental Science Key Terms & Definitions
- Environment: The sum of all living (biotic) and non-living (abiotic) factors affecting an organism or ecological system.
- Biotic Factor: A living component of an ecosystem (e.g., plants, animals, bacteria).
- Abiotic Factor: A non-living component of an ecosystem (e.g., sunlight, temperature, water).
- Environmental Science: The interdisciplinary study of how humans interact with the environment.
- Environmentalism: A social movement aimed at protecting the natural world.
- Culture: The collective beliefs, values, and practices that affect human behavior and interaction with the environment.
- Stewardship: Responsible management and care for the environment.
- Anthropocentric: A worldview that places humans as the most important element.
- Biocentric: A worldview that values all living organisms.
- Ecocentric: A worldview that values entire ecosystems.
- Utilitarian: Prioritizing the practical and economic benefits of resources.
- Preservation: Protecting the environment by limiting human interference.
- Conservation: Managing natural resources to sustain them long-term.
- Environmental Ethics: The moral principles that guide human interaction with the environment.
- Renewable Resource: A resource replenished naturally over short periods (e.g., sunlight, wind).
- Nonrenewable Resource: A resource that forms slowly and is finite (e.g., fossil fuels, minerals).
- Nomadic Lifestyle: A way of life where people move frequently in search of food and resources.
- Agricultural Revolution: The shift from nomadic lifestyles to settled farming.
- Industrial Revolution: A period marked by significant industrialization, increasing energy use and resource demand.
- Consumption: The use of goods and resources by individuals/societies.
- Ecological Footprint: A measure of human demand on Earth's resources.
- Independent Variable: The variable manipulated in an experiment.
- Dependent Variable: The variable measured in an experiment.
- Qualitative Data: Non-numerical data.
- Quantitative Data: Numerical data.
- Manipulative Experiment: An experiment where the researcher actively changes the independent variable.
- Controlled Experiment: An experiment comparing a control group to one or more experimental groups to isolate variable effects.
Key Concepts and Explanations
- Biotic and Abiotic Factors: Examples of biotic factors include trees, deer, and fungi, while abiotic factors include sunlight, soil, and water.
- Goals of Environmental Science vs. Environmentalism: Environmental science uses data and research to understand interactions and find solutions. Environmentalism advocates for the protection of nature.
- Interdisciplinary Nature of Environmental Science: Environmental science combines various disciplines, such as biology, chemistry, physics, geology, and social sciences, to solve environmental problems.
- Requirements for Life: Basic needs include energy, nutrients, water, and suitable temperatures.
- Exxon Valdez Oil Spill: A significant event involving the release of crude oil in 1989.
- Scientific Method: A process involving observation, hypothesis formation, experimentation, data analysis, and conclusions, exemplified by testing how fertilizer affects plant growth.
- Variables in Experiments: The independent variable is a factor manipulated in an experiment, while the dependent variable is the outcome being measured.
- Control and Experimental Types: A control group receives no treatment or a standard treatment, while the experimental groups receive a variable treatment.
- Culture and Worldview: Different cultures may have differing interpretations of environmental issues. Western cultures often focus on economic gain ("anthropocentric"), while some others prioritize harmony with nature.
- Preservation vs. Conservation: Preservation aims to protect areas from human interference, while conservation practices involve managing resources to ensure long-term sustainability.
- Tragedy of the Commons: Hardin's analogy demonstrating the dangers of shared resources and the importance of responsible resource management, exemplified by overfishing in oceans.
- Easter Island Case Study: A historical example of resource overuse leading to societal collapse.
- Revolutions and Resource Use: Examples of revolutions changing resource use include the Agricultural Revolution and the Industrial Revolution.
- Graphing Experimental Data: Axes (X and Y) are used to plot independent and dependent variables.
- Science vs. Pseudoscience: Science relies on verifiable evidence, while pseudoscience lacks scientific rigor and isn't reproducible.
Earth Systems and Cycles
- Chemistry: The study of matter, its properties, and interactions with energy and other matter.
- Biology: The study of living organisms and their interactions.
- Ecology: The study of the relationship between organisms and their environment.
- Matter: Anything that has mass and occupies space.
- Law of Conservation of Matter: Matter can't be created or destroyed; it can only change form.
- Chemical Reactions: Processes that transform substances into new substances.
- Organic Compound: Any molecule containing carbon and hydrogen, often associated with living things.
- Hydrocarbon: Organic compounds made up completely of carbon atoms and hydrogen atoms.
- Combustion Reaction: A rapid chemical reaction with a hydrocarbon and oxygen to form carbon dioxide and water.
- Endothermic: Absorbing energy from surroundings.
- Exothermic: Releasing energy into surroundings.
- Metabolism: The sum total of all chemical reactions in a living organism.
- Population: A group of organisms of the same species in a particular region.
- Community: All the interacting organisms in a particular area.
- Bioremediation: Utilizing organisms, such as bacteria, to remove pollutants from the environment.
Additional Concepts
- Atmosphere: The layer of gases surrounding Earth.
- Hydrosphere: All water on Earth.
- Geosphere: Earth's solid parts (rocks, soil, landforms).
- Biosphere: All living organisms and ecosystems on Earth.
- Layers of Earth: Core, mantle, crust, asthenosphere, lithosphere.
- Tectonic Plates: Large sections of Earth's lithosphere that shift and interact, causing earthquakes, volcanoes, and mountain building.
- Natural vs. Laboratory Experiments: Differences in methodology and control over variables.
- Correlation vs. Causation: Identifying factors influencing each other without necessarily implying that one directly causes the other.
- Models: Simplified representations of systems used to gain insight.
- Peer Review: Evaluation of scientific work by experts.
