It has a hook or hole at one end, is made from wood, metal, plastic or composite material, and is driven into the ground for holding a tent, either directly by putting it through the grommets, or by connecting to ropes attached to the tent. A tent peg can be improvised from a small branch.
Armies on the move have often used tents for sleeping accommodation. The enemy initiated an attack by riding horse back at speed knocking out the tent pegs, collapsing the tents on the enemy as they slept while a more direct attack took place. This has now developed into an equestrian sport called tent pegging.
A tepee fire lay is one where the kindling material is laid in a formation that resembles a tepee with the tinder material nesting inside it. This ensures that the heat generated from the tinder accesses and combusts the kindling quickly. This is one of the more common campfire fire lays.

This sovereignty extends to the airspace over and seabed below.
A line drawn to join the lowest points along the entire length of a stream bed or valley in its downward slope, defining its deepest channel. The thalweg thus marks the profile of a watercourse. The term is also sometimes used to refer to a subterranean stream that percolates under the surface and in the same general direction as the surface stream.
If the boundary between two political entities is stated to be a waterway, the boundary follows the thalweg of that watercourse. In particular, the boundary follows the center of the principal navigable channel of the waterway, which is presumably the deepest part. If there are multiple navigable channels in a river, the one principally used for downstream travel, likely to have the strongest current, is used.
A column of rising air at lower altitudes created by uneven heating of Earth’s surface from solar radiation. Dark earth, urban areas, and roadways are good sources of thermals. They are often indicated by the presence of visible cumulus clouds at the apex of the thermal. With steady wind, thermals and cumulus clouds align in rows oriented to wind direction. Thermals are one of the many sources of lift used by soaring birds and gliders to soar.

Many ticks carry disease and removal of the tick, particularly the head that is embedded inside the skin, is extremely important.
Occurs where a river empties into the sea. It pushes up the river, against the current. A tidal bore is a true tidal wave. Its occurrence is relatively infrequent and requires the river to be fairly shallow with a narrow outlet to the sea, with the estuary being wide and flat. The tidal range must be (usually) at least about 20 feet.
The distance a boat floats due to the speed to of the tide, without any additional steeering or paddling.
The vertical difference between the high tide and the succeeding low tide. This distance changes with the position of the Moon relative to the Sun and the Earth. Tidal ranges are classified as: (1) Micromareal, when the tidal range is lower than 2 metres, (2) Mesomareal, when the tidal range is between 2 metres and 4 metres, and (3) Macromareal, when the tidal range is higher than 4 metres.
The periodic movement of water in a horizontal direction due to tides. The tidal stream associated with a rising tide is called the flood stream and that with a falling tide is called the ebb stream. A tidal stream is often described by the direction to which it runs.
Rise and fall of ocean water caused by the effects of gravitational forces exerted by the Moon, Sun and rotation of the Earth. Some shorelines experience a semi-diurnal tide, two nearly equal high and low tides each day. Other locations experience a diurnal tide, only one high and one low tide each day.

A violently twisting column of air connecting the ground with a cumulonimbus cloud. It looks like a funnel and as it travels, with wind speeds of around 180 kmph, it destroys pretty much everything in its path. They usually dissipate within a few kilometres, but some larger more devastating can wreck havoc and destruction over hundreds of kilometres.

Often done low to the ground but can be done on highlines as well. A great number of tricks can be done on the line, and because the sport is fairly new, there is plenty of room for new tricks. Some of the basic tricks done today are walking forwards and backwards, turns, drop knee, running and jumping onto the slackline to start walking and bounce walking. Some intermediate tricks include: Buddha sit, sitting down, lying down, cross-legged knee drop, surfing forward, surfing sideways, and jump turns. Some of the advanced tricks are jumps, tree plants, jumping from line-to-line, 360s, butt and chest bounces. With advancements in webbing technology and tensioning systems, the limits for what can be done on a slackline are being pushed constantly. It is not uncommon to see expert slackliners incorporating flips and twists into slackline trick combinations.
