Famine

The condition in which food insecurity is so extreme that large numbers of deaths occur in a given area over a relatively short period

Application:

Human nutritional requirements are not always satisfied. Food insecurity.

Fault

A fracture in rock caused by a movement of Earth’s crust

Application:

Where earthquakes occur.

Fault Zone

A large expanse of rock where a fault has occurred

Application:

Seismic activity occurs here.

Fecal Coliform Bacteria

A group of microorganisms in the human intestines that can serve as an indicator species for potentially harmful microorganisms associated with contamination by sewage

Application:

The best indicators for potentially harmful water

Feedback

An adjustment in input or output rates caused by changes to a system

Application:

A natural system can respond to changes in its inputs and outputs.

First Law of Thermodynamic

s

A law of nature stating that energy can neither be created nor destroyed

Application:

You can’t get something from nothing.

Fish Ladder

A stair-like structure that allows migrating fish to get around a dam

Application:

Alleviates the interruption of the natural flow of water, caused by dams, to which many organisms are adapted

Fishery

A commercially harvestable population of fish within a particular ecological region

Application:

Can be applied to tragedy of the commons

Fishery Collapse

The decline of a fish population by 90 percent or more

Application:

Caused by the decrease in difficulty of catching fish due to the advancements in fish catching techniques and the enlargement of fish catching vessels

Fission

A nuclear reaction in which a neutron strikes a relatively large atomic nucleus, which then splits into two or more parts, releasing additional neutrons and energy in the form of heat

Application:

Aspect in nuclear energy used to produce steam, just as in any other thermal power plant.
