The Bear Seamount (left), a guyot in the northern Atlantic Ocean. In marine geology, a guyot (/ ˈ ɡ iː. oʊ, ɡ iː ˈ oʊ /), [1] [2] also called a tablemount, is an isolated underwater volcanic mountain with a flat top more than 200 m (660 ft) below the surface of the sea. [3] The diameters of these flat summits can exceed 10 km (6 mi). [3]
An autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below. [6] [7] The downward component of the total aerodynamic reaction of the rotor gives lift to the vehicle, sustaining it in the air. A separate propeller provides forward thrust and can be placed in a puller configuration ...
A vapor cone (also known as a Mach diamond, [1] shock collar, or shock egg) is a visible cloud of condensed water that can sometimes form around an object moving at high speed through moist air, such as an aircraft flying at transonic speeds. When the localized air pressure around the object drops, so does the air temperature.

The buoyancy, in both cases, is equal to the weight of fluid displaced - Archimedes' principle holds for air just as it does for water. A cubic meter of air at ordinary atmospheric pressure and room temperature has a mass of about 1.2 kilograms, so its weight is about 12 newtons. Therefore, any 1-cubic-meter object in air is buoyed up with a ...
United States Air Force F-15C Eagles flying in a Vic formation over Alaska. Formation flying is the flight of multiple objects in coordination. Formation flying occurs in nature among flying and gliding animals, and is also conducted in human aviation, often in military aviation and air shows.
Where an aircraft passes through a cloud, it can disperse the cloud in its path. This is known as a distrail (short for "dissipation trail"). The plane's warm engine exhaust and enhanced vertical mixing in the aircraft's wake can cause existing cloud droplets to evaporate.
A bird or bat flying through the air at a constant speed moves its wings up and down (usually with some fore-aft movement as well). Because the animal is in motion, there is some airflow relative to its body which, combined with the velocity of its wings, generates a faster airflow moving over the wing.
