Length of water over which a given wind has blown. It is the main factor creating storm surges leading to coastal erosion and flooding. Fetch length, along with the wind speed, determines the sea state of waves produced. Longer the fetch and faster the wind speed, the more wind energy is imparted to the water surface resulting in a larger sea state.
Temperature above the normal range due to an increase in the body’s temperature set-point - uually between 37.5° and 38.3°C (99.5° and 100.9°F).The increase in set-point triggers increased muscle contraction and causes a feeling of cold resulting in heat production and efforts to conserve heat. Fevers do not typically go higher than 41° to 42°C (105.8° to 107.6°F).
Type of pyrotechnic producing a brilliant light or intense heat without an explosion. Used for signalling. May be ground or projectile based, or parachute-suspended to provide maximum illumination time.

A large area dominated by trees, they are the dominant terrestrial ecosystem distributed across the globe, accounting for 75% of the gross primary productivity of the Earth’s biosphere, and containing 80% of plant biomass. Forests at different latitudes and elevations form distinctly different ecozones - boreal forests near the poles, tropical forests near the equator and temperate forests at mid-latitudes. Higher elevation areas tend to support forests similar to those at higher latitudes.

A anaerobic, rod-shaped, non-sporulating bacterium. Increased levels of fecal coliforms provide a warning of failure in water treatment, a break in the integrity of the distribution system, possible contamination with pathogens. When levels are high there may be an elevated risk of waterborne gastroenteritis. The presence of fecal coliform in aquatic environments may indicate that the water has been contaminated with the fecal material of humans or other animals. Fecal coliform bacteria can enter rivers through direct discharge of waste from mammals and birds, from agricultural and storm runoff, and from human sewage. Some waterborne pathogenic diseases that may coincide with fecal coliform contamination include ear infections, dysentery, typhoid fever, viral and bacterial gastroenteritis, and Hepatitis A.
A man made metallic material that produces sparks in excess of 3,000°C when struck against iron or steel. This property makes it a valuable fire starter and is found commonly in cigarette lighters and are also available as rods. These are also called ferro rods, fire steel, flint starters, etc.

A way of broadcasting radio signals in the form of electromagnetic waves. In FM broadcast sound is encoded by varying the frequency of the wave while the amplitude is kept constant.
Distance at which light rays are brought to single pointed focus is the focal length of the material being used. Important when lighting fires with a magnifying glass, since the rays of the Sun through the glass have to be concentrated at the focal point for kindling to combust.
A portable hacksaw that folds back into a handle like a knife. It makes cutting wood a lot easier than hacking away with a knife in the absence of an axe.
The linear transfer of energy in the form of food, from one organism to another. Intertwined food chains make up a food web since most organisms consumer more than one type of food.
A discipline describing handling, preparation and storage of food in ways that prevent food borne illnesses. Food can transmit disease from person to person as well as serve as a growth medium for bacteria that can cause food poisoning. The five key principles of food safety are (1) prevent contaminating food with pathogens spreading from people, pets, and pests, (2) separate raw and cooked foods to prevent contamination, (3) cook foods for the appropriate length of time and at the appropriate temperature to kill pathogens, (4) store food at the proper temperature, and (5) use safe water and raw materials.
A collection of the uppermost layer of mature trees in a forest that often intertwine or touch. Thick, dense canopies can block sunlight from coming through.

In the majority of countries free climbing is a form of rock climbing without any equipment or ropes. In the USA, free climbing is specifically contrasted with aid climbing. Like aid climbing, it may use ropes and other means of climbing protection, but only to protect against injury during falls but not to assist progress.
Form of underwater diving that relies on the ability to hold breath until resurfacing rather than on the use of a breathing apparatus.
A form of free and solo climbing where the climber climbs alone without any ropes, harnesses or protective equipment, relying entirely on skill. Free soloists typically climb above safe heights, where a fall would always result in serious injury or death.
Freedom of the Seas
A principle in the international law and law of the sea stressing freedom to navigate the oceans. It also disapproves of war fought in water. The high seas are open to all states, whether coastal or land-locked including navigation, overflight, the laying of submarine cables, building artificial islands, fishing and scientific research.
Art and practice of cultivating balance on a piece of rope or webbing draped slack between two anchor points, typically about 15 to 30 feet apart and 2 to 3 feet off the ground at the centre. This type of very “slack” slackline provides a wide array of opportunities for both swinging and static manoeuvers. A freestyle slackline has no tension in it, while traditional slacklines are tensioned.
Freeze Drying Food
Process of preserving food by first freezing and then warming in a manner that the moisture trapped in the food in the form of ice goes from a solid state to a gaseous state. Freeze drying food affects its texture more than other preservation methods, but nutritional value and flavour stays intact. Being light, it’s great for backpacking or storing in emergency kits.
Water containing less than 0.5gm/litre of total dissolved mineral salts is termed as fresh water. It is generally found in ice caps, glaciers, icebergs, rivers, streams, ponds, lakes, etc.
