What is an EVS?

An environmental value system


100

A ___ ____exchanges both energy and matter across its boundary while a closed system only exchanges energy across its boundary

Open System

100

-------- is defined as the useful energy, the work or output produced by a process divided by the amount of energy consumed being the input to the process. 



What is efficiency?

100

__ is the use and management of resources that allows full natural replacement of the resources exploited and full recovery of the ecosystems affected by their extraction and use

What is sustainability?

100

A system may best be defined as __


What is an assemblage of functioning parts without inputs or outputs?

200

A value system that influences the way that we view the world.


(Any aspect of culture)

  • Language

  • Religion 

  • Tradition

200

A ___ ____ is a hypothetical concept in which either energy nor matter is exchanged across the boundary


Isolated System

200

----- is a measure of the amount of disorder in a system


What is Entropy?

200

___ Is the natural yield obtained from natural resources

What is natural income?

200

Name an input to a closed system.

What is heat energy?

300

What is a technocentric view point?


A technocentric view point argues that technological developments can provide solutions to environmental problems. 


300

Systems can we thought of as one of three types. The three being -- --- --

Open, Closed, & Isolated

300

------- of thermodynamics is the principle of conservation of energy, which states that energy is an isolated system can be transformed but cannot be created or destroyed.

what is the first law of thermodynamics

300

What are EIA's?

What is Environmental Impact Assessments?


400

What is an ecocentric view point?

An ecocentric view point integrates social, spiritual, and environmental dimensions into a holistic ideal. It puts ecology and nature as central to humanity and emphasizes a less materialistic approach.

400

--- occur when energy or matter flows and changes location but does not change its state


Transfers

400

-------- refers to the fact that energy is transformed through energy transfers.  Entropy is a measure of the amount of disorder in a system.  An increase in entropy arising from energy transformations reduces the energy available to do work.  

What is the second law of thermodynamics?

400

An ___ model is used to estimate the demands that human populations place of the environment

What is an ecological footprint?

400

Name a major source of pollutants 


What is:

Combustion of Fossil Fuels

Domestic Waste

Industrial Waste 

Agricultural Waste

500

What is the world’s worst industrial disaster?


Bhopal Disaster (India)

500

A ___ ____exchanges both energy and matter across its boundary while a closed system only exchanges energy across its boundary

Open system

500

___ is reached when an ecosystem experiences a shift to a new state in which there are significant changes to its biodiversity and the services it provides.

What is an ecological tipping point in ecological reference?

500

When changing what we do seems too difficult

What is Inertia?


500

Describe pollution.

What is an activity, at a rate greater than that at which it can be rendered harmless by the environment, and which has an appreciable effect on the organisms within it.
