Radioactive decay, also known as nuclear decay or radioactivity, is the process by which a nucleus of an unstable atom loses energy by emitting radiation. A material that spontaneously emits such radiation â which includes alpha particles, beta particles, gamma rays and conversion electrons â is considered radioactive.
Best Answer: Four of the larger Australian deserts are the Great Victoria Desert, the Gibson Desert, the Tanami Desert and the Great Sandy Desert. That accounts for most of the west of the continent, nearly two-thirds. Name four states that would be included in at least one of the North American deserts.
The vast Great Victoria Desert extends from the Eastern Goldfields area in Western Australia across the southern parts of central Australia to the Stuart and Gawler Ranges in South Australia. The climate is arid, with mean annual rainfall ranging from below 150 mm to over 250 mm (Laut 1977a, b, Newby 1984).
