Chapter 1 Flashcards
Anthropogenic
Manmade
Closed System
Energy can cross but not matter
Controlled Experiment
Identify independent and dependent variables and make predictions
Dependent Variable
Measured during experiment
Developing Nations
Less affluent countries with lower GDP’s
Ecological Footprint
Amount of biologically productive land and water required to provide resources
Ecosystem Services
Nature providing valuable resources
Environmental Ethics
All life has a right to exist
First Law of Thermodynamics
Energy cannot be cheated or destroyed, only converted
Independent Variable
Manipulated
Heat
Special form of energy
Half Life
The amount of time it takes one half of a sample to decay
Input
Matter and energy enter a system
Isolated System
Neither energy or matter can be exchanged
Negative Feedback Loop
Initial change of a system undone by a series of changes
Non-point Source
Pollutants introduced over a large area
Nonrenewable Resource
Resource not renewed over time
Open System
Energy and matter exchange across boundaries
Output
Energy and matter leave system
Per Capita
Per person
pH
Logarithmic scale ranging from 0-14
Point Source
Pollutants introduced in a single set or point
Poverty
Not able to achieve sustainability and environmental protection
Power
Rate at which energy is used related but not the same as energy
Renewable Resource
Resources renewed over time
Second Law of Thermodynamics
All energy conversions must always be produced
Sustainability
Using a resource at the rate that is less than or equal to the rate at which it is naturally replenished
Tragedy of Commons
Common- resource that is free and available to everyone
Tragedy- degradation of the resource
Affluence
Wealth
