Intro
educated guess
measurement if acidity or alkalinity
what is pH
the set of all chemical reactions that occur in all living organisms to maintain life
what is metabolism
anything that has mass and takes up space
what is matter
accounting tool that uses land to show how much area a population is using for consumption, production, and waste discharge
what is ecological footprint
the process of gaining knowledge about the natural world
what is science
produce H+ ions in solutions
what is an acid
bond that involves SHARING of electrons
same type of matter
what is an element
People must proceed carefully when an activity threatens human health of environment
what is the precautionary principle
Pure science that seeks knowledge
what is basic science
produce OH- ions in solutions
what is a base
involves TRANSFER of electrons
what is an ionic bond
2 or more elements chemically bonded to make a new substance
what is a molecule
Land includes soil, water, plants, and animals; man is just a member of the community, not the boss
what is land ethic
uses science to solve a real work problem; has an underlying question or problem to solve
what is applied science
Keep the pH within a specific range
what is a buffer
equal sharing of electrons
what is non-polar
same element with different masses (change in neutrons)
what are isotopes
People treat Earth as a finite resource
what is sustainable ethic
What is environmental science
what is dynamic, disciplinary study of the interactions of the living and nonliving parts of the environment with a focus on human impact
contain carbon
what are organic molecules
affinity for electrons which affects the type of bond
what is electonegativity
radioactive isotopes
what are radioisotopes
earth is unlimited supply; keep moving to another location when resources are gone
what is frontier ethic
