Tides
The state of the tide when at its lowest level.
What is a low tide?
Waves that are formed when the wave collapses on top of itself.
What is a breaking wave?
An Executive Agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. Services include a website with weather information, forecasts and radar.
What is the Bureau of Meteorology?
a formation on the ocean's surface are commonly caused by wind transferring its energy to the water. Can travel over long distances. Size depends on wind speed, wind duration, and the area over which the wind is blowing.
What is a wave?
Also known as the front crawl, is the fastest and most efficient of the four competitive swimming strokes.
What is freestyle?
A tide caused moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon.
What is a high tide?
A wave produced when the ocean floor has a slope, these waves disperse the energy over a large area when the wave reaches a sloping sandy beach.
What is a spilling wave?
A storm with thunder and lightning and typically also heavy rain or hail.
What is a thunderstorm?
Swimming in a safe place at the beach.
What is swimming between the flags?
A swimming stroke performed on the back with the arms lifted alternately out of the water in a backward circular motion and the legs extended and kicking.
What is backstroke?
A term for an especially high spring tide. It is not a scientific term, nor is it used in a scientific context.
What is a king tide?
A wave produced when the ocean floor is steep or the bottom has sudden depth changes, these waves’ crest curls, moving over a pocket of air and explodes when it reaches a steeper beach.
What is a plunging wave?
A person who forecasts and reports the weather.
What is a meteorologist?
A powerful, narrow channels of fast-moving water that are prevalent along the coasts. You should not attempt to swim directly into shore, but across to get out.
What is a rip current?
A swimming stroke swum on the chest, with both arms moving symmetrically, accompanied by the dolphin kick.
What is butterfly stroke?
A tide just after a new or full moon, when there is the greatest difference between high and low water.
What is a spring tide?
A wave produced when long period swells reach coastlines with steep beach profiles, these wave’s travels fast without allowing the crest to evolve.
What is a surging wave?
A system that has lower pressure at its centre than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapour within it condenses forming clouds and often precipitation too.
What is a low pressure system?
This entry is chosen when entering deep water from a low edge/bank or when the swimmer needs to watch someone or something on entry. The swimmers aim is to prevent their head from submerging.
What is a stride entry?
What a swimmer can do while in a vertical position to keep their head above the surface of the water, while not providing sufficient directional thrust to overcome inertia and propel the swimmer in any specific direction.
What is treading water?
A tide just after the first or third quarters of the moon when there is least difference between high and low water.
What is a neap tide?
A blend of surging and plunging waves, collapsing waves’ crest never breaks completely and its bottom face gets vertical and collapses, turning into white water.
What is a collapsing wave?
Systems that are frequently associated with light winds at the surface and subsidence through the lower portion of the troposphere. In general, subsidence will dry out an air mass by adiabatic or compressional heating. They typically brings clear skies.
What is a high pressure system?
A long, narrow sandbank, especially at the mouth of a river.
What is a sandbar?
A swimming stroke used as a life preserving stroke to be able to swim long distances, conserving energy, minimizing heat loss, all whilst awaiting rescue.
What is survival backstroke?
