It is operated by the non-profit Educational Media Foundation and is syndicated on dozens of stations across 42 states in cities including San Bernardino, San Diego, Houston, Dallas-Fort Worth, Seattle-Tacoma, Portland, Phoenix, Oklahoma City, Tulsa, Ventura, Thousand Oaks, Kansas City, Virginia Beach-Norfolk, Burlington, Jacksonville and portions of Los Angeles.

History

In 1986, KLRD began broadcasting Christian music from Yucaipa, California, and went by the on-air moniker K-LORD. In 1994, KXRD was started as a sister station to KLRD. In 1995, K-LORD changed their name to "Air 1" and began broadcasting via satellite from St. Helens, Oregon. In 1999, Air 1 joined with EMF Broadcasting (the former name of KLA1 Foundation), and finally in 2002, it moved its headquarters to Rocklin, California. Air 1 makes use of broadcast translators to spread the signal across much of the country. As of November 2011, the network lists 90 full powered radio stations and 125 translators of various power levels reaching 40 states.

Atmosphere of Earth

The atmosphere of Earth is the layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).

The common name air (English pronunciation: /ɛər/) is given to the atmospheric gases used in breathing and photosynthesis. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air content and atmospheric pressure vary at different layers, and air suitable for the survival of terrestrial plants and terrestrial animals is found only in Earth's troposphere and artificial atmospheres.

The atmosphere has a mass of about 5.15×10¹⁸ kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. The Kármán line, at 100 km (62 mi), or 1.57% of Earth's radius, is often used as the border between the atmosphere and outer space. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi). Several layers can be distinguished in the atmosphere, based on characteristics such as temperature and composition.

Air (classical element)

Air (also sometimes called Wind) is often seen as a universal power or pure substance. Its fundamental importance to life can be seen in words such as aspire, inspire, perspire and spirit, all derived from the Latin spirare.

Greek and Roman tradition

Air is one of the four classical elements in ancient Greek philosophy and science. According to Plato, it is associated with the octahedron; air is considered to be both hot and wet. The ancient Greeks used two words for air: aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds.Plato, for instance writes that "So it is with air: there is the brightest variety which we call aether, the muddiest which we call mist and darkness, and other kinds for which we have no name...." Among the early Greek Pre-Socratic philosophers, Anaximenes (mid-6th century BCE) named air as the arche. A similar belief was attributed by some ancient sources to Diogenes Apolloniates (late 5th century BCE), who also linked air with intelligence and soul (psyche), but other sources claim that his arche was a substance between air and fire.Aristophanes parodied such teachings in his play The Clouds by putting a prayer to air in the mouth of Socrates.
