Cloud

In meteorology, a cloud is an aerosol comprising a visible mass of liquid droplets or frozen crystals made of water or various chemicals. The droplets or particles are suspended in the atmosphere above the surface of a planetary body. On Earth clouds are formed by the saturation of air in the homosphere when air cools or gains water vapor.

Cloud types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names due to the universal adaptation of Luke Howard's nomenclature. It was formally proposed in December 1802 and published for the first time the following year. It became the basis of a modern international system that classifies these tropospheric aerosols into several physical forms which can be found at various altitude levels or étages.

Top

A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.

Characteristics

The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.

Super Smash Bros.

Super Smash Bros., known in Japan as Dairantō Smash Brothers (Japanese: 大乱闘スマッシュブラザーズ, Hepburn: Dairantō Sumasshu Burazāzu, lit. "Great Melee Smash Brothers"), is a series of crossover fighting games published by Nintendo, that primarily featuring characters from franchises established on its systems. All five games have been directed by Masahiro Sakurai.

The gameplay objective differs from that of traditional fighters by aiming to knock opponents out of the stage instead of depleting life bars. The original Super Smash Bros., released in 1999 for the Nintendo 64, had a small budget and was originally a Japan-only release, but its domestic success led to a worldwide release. The series achieved even greater success with the release of Super Smash Bros. Melee, which was released in 2001 for the GameCube and became the best-selling game on that system. A third installment, Super Smash Bros. Brawl, was released in 2008 for the Wii. Although HAL Laboratory has been the developer of the first two titles, the third game was developed through the collaboration of several companies. The fourth and fifth installments,Super Smash Bros. for Nintendo 3DS and Wii U, were released in 2014 for the Nintendo 3DS and Wii U, respectively. The 3DS installment was the first series title to be released on a handheld platform.
