An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. perfect insulator does not exist, because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms.
From Wikipedia, the free encyclopedia. The Tabernas Desert (Spanish: Desierto de Tabernas) is one of Spain's semi-deserts, located within Spain's southeastern province of AlmerÃ­a. Almeria is the driest region of Europe, with the continent's only true desert climate where annual rainfall reaches levels as low as 156 mm in coastal areas.
A desert is a landscape that typically has very little precipitation (rain), high heat, and a distinct lack of plant life â desert plants like cactus adapt to thrive with less water.

It is the worldâs hottest desert and the third largest desert on the planet. Some of the sand dunes in the Sahara can reach as high as 590 feet tall!
