Ozone–oxygen cycle Ozone–oxygen cycle The ozone–oxygen cycle is the process by which ozone is continually regenerated in Earth's stratosphere, converting ultraviolet radiation (UV) into heat. In 1930 Sydney Chapman resolved the chemistry involved. The process is commonly called the Chapman cycle by atmospheric scientists. Most of the ozone production occurs in the tropical upper stratosphere and mesosphere. The total mass of ozone produced per day over the globe is about 400 million metric tons. The global mass of ozone is relatively constant at about 3 billion metric tons, meaning the Sun produces about 12% of the ozone layer each day. And if
Stratosphere: Conquest of the Skies Stratosphere: Conquest of the Skies Stratosphere: Conquest of the Skies is a Vehicular combat game and also a real-time strategy PC game, developed by Kodiak Interactive and published by Ripcord Games in 1998. Stratosphere focuses on floating island battles which players control. Gameplay consist of the player controlling a single floating island which are called flying fortresses in the game. These fortresses float because they are built from 'floatstones' which can be collected from mountainsides and also from other fortresses after damaging them. There are three types of floatstones each used to build different structures on the fortress. Extra land
