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.
If the last number is correct then the Great Victoria Desert in Australia is the third largest desert in the world, after the Sahara and the Arabian Desert. If the first number is correct it would still make it to number eight on the list, followed by the Great Sandy Desert.
