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
environment’s natural processes that provide us with resources to support life
ecosystem services
social movement based on political & ethical views of environment
environmentalism
preservationist
John Muir
believe that an environment should be maintained in its pristine form & its resources shouldn’t be harvested for human use
preservationist
Muir created…
The Sierra Club
the environment & its resources should be used by humans & managed in a responsible manner
conservation
natural resources will be used in a manner that will meet present-day needs without jeopardizing the supply of the resource for future generations
sustainable
when all the trees are removed at the same time
clear-cut
lands & their natural resources should not be consumed by humans & should instead be maintained in their pristine form
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
specific factors that can be manipulated
variables
factor that the scientist alters
independent variable
factor that is being measured
dependent variable
control of how each variable influences the experiment
controlled experiment
analyzing the data & making conclusions about the hypothesis
interpret the results
other scientists comment on & approve proposed manuscripts
peer reviewed
