River

A river is a natural waterway that transits water through a setting from higher to lower elevations. A river may have its basis in a spring, lake, from damp, boggy landscapes where the soil is waterlogged, from glacial melt, or from surface runoff of precipitation. Almost each and every one river is joined by other rivers and streams termed tributaries the highest of which are known as headwaters. Water may also begin from groundwater sources. Throughout the course of the river, the total volume transported downstream will often be a combination of the free water flow together with a important contribution flowing through sub-surface rocks and gravels that underlie the river and its floodplain. For many rivers in large valleys, this unseen component of flow may greatly go above the visible flow.
From their source, all rivers flow downhill, typically terminating in the sea or in a lake, through a confluence. In arid areas rivers sometimes end by losing water to desertion. River water may also infiltrate into the soil or pervious rock, where it becomes groundwater. Excessive abstraction of water for use in commerce, irrigation, etc., can also cause a river to dry before success its natural terminus.

Solar wind

The solar wind is a stream of charged particles which are expelled from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons that are able to get away the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Clothing

Clothing protects the vulnerable nude human body from the extremes of weather, other features of our situation, and for safety reasons. Every article of clothing also carries a enriching and social meaning. Human beings are the only creatures known to wear clothing, with the exemption of pets clothed by their owners. People also decorate their bodies with makeup or foundation, perfume, and other ornamentation; they also cut, dye, and organize the hair of their heads, faces, and bodies, and sometimes also mark their skin. All these streamers contribute to the overall effect and message of clothing, but do not constitute clothing per se.

Articles carried rather than worn are normally counted as fashion garnishing rather than as clothing. Jewelry and eyeglasses are usually counted as accessories as well, even though in general speech these items are described as being worn rather than carried. The practical function of clothing is to protect the human body from dangers in the surroundings: weather, insects, noxious chemicals, weapons, and get in touch with with abrasive substances, and other hazards. Clothing can protect against many things that might injure the naked human body. In some cases clothing protects the environment from the clothing wearer as fine.

Humans have shown intense inventiveness in devising clothing solutions to practical problems and the difference between clothing and other protective equipment is not always clear-cut. See, among others: air inured clothing, armor, diving suit, swimsuit, bee-keeper's uniform, motorcycle leathers, high-visibility garments, and protective clothing.
