Environment: The Science Behind The Stories Chapter 5 Notes Questions and Answers 2023
watershed - -land area that funnels water to the bay through rivers
-hypoxia - -when phytoplankton die, settle to the bay bottom and are decomposed by bacteria, oxygen in the water is depleted
-system - -network of relationships among parts, elements, or components that interact with and influence one another through the exchange of energy, matter or information
-feedback loop - -a system's output serving as an input to that same system
-negative feedback loop - -output that results from a system moving in one direction acts as input
that moves the system in the other direction
-positive feedback loop - -opposite effect rather than stabilizing, they drive it further toward an extreme
-dynamic equilibrium - -when processes move in opposing directions at equivalent rates so that their effects balance out in a system stabilized by negative feedback
-homeostasis - -tendency of a system to maintain constant or stable internal conditions
-emergent properties - -characteristics not evident in the components alone
-runoff - -precipitation that flows over land and enters waterways
-airshed - -the geographic area that produces air pollutants that are likely to end up in a waterway
-eutrophication - -process of nutrient over-enrichment, blooms of algae, increased production of organic matter and subsequent ecosystem degradation
-lithosphere - -rock and sediment beneath our feet, the planet's uppermost mantle and crust
-atmosphere - -composed of the air surrounding our planet
-hydrosphere - -encompasses all water
-biosphere - -consists of all the planet's organisms and abiotic portions of the environment organisms and abiotic portions of the environment with which they interact
-ecosystem - -consists of all organisms and nonliving entities that occur and interact in a particular area at the same time
