Unit 1 Study.com Flashcards
incorporates info & ideas from multiple disciplines
interdisciplinary field
variety of substances & energy sources that we take from the environment & use
natural resources
can be replenished over time (sun, wind, soil, wood)
renewable natural resources
infinite supply & will run out (minerals, oil)
nonrenewable natural resources

ecosystem services
social movement based on political & ethical views of environment

preservation
valuable in itself simply by existing
intrinsic value
forests that are re-growing after a disturbance
secondary growth forests
process of asking questions, making observations, & developing experiments to investigate & learn more about a specific topic
science
info gathered about the problem through observations & experiments
scientific assessment
investigate potential harm to human health or the environment as a result of the specific problem or management options
environmental risk assessment
citizens are informed about environmental problem & presented with potential solutions & risks associated with the problem
public engagement
risks associated with each possible solution are weighed against each other by politicians & a legal decision is made about how to handle the environmental problem
political action
the environmental problem & location are monitored after the solution is implemented
long-term environmental management
structured technique used to test ideas & potential answers to scientific questions
scientific method
proposed explanation that aims to answer the question formulated- must be testable through experimentation
hypothesis
activity designed to gather data that will be used to support or reject the hypothesis
experiment
