its not man made, it was created naturally.
No the great barrier reef is a natural phenomenon and protected as much as possible from interference by man.
The first man made device to break the sound barrier is the whip. The first pilot to break the sound barrier was Chuck Yeager, flying a Bell X-1 at Mach 1 in October of 1947.
The Great Barrier Reef is natural because it hasn't been man-made.
Probably the whip. The distinctive crack of a whip is made when the end of it breaks the sound barrier.
No is not ! Asus is Chinas PC Company :D
The Bell X-1, a rocket-powered aircraft, was the first man-made item to break the sound barrier in level flight in 1947. It was flown by pilot Chuck Yeager.
The Great Barrier Reef is a giant coral reef. It is basically a large collection of aragonite structures produced by living organisms. In a sense, it is neither man made nor God made. (If you are a creationist, and believe that God created all the creatures of the earth, then you could say that the Great Barrier Reef was indirectly made by God or a byproduct of Gods creation).
It is not man made, but a natural feature. Natural features do not HAVE reasons- they ARE.
The Great Barrier Reef is not a man-made structure. As it has been built by coral polyps, it continues to be built upon constantly. The Great Barrier Reef is constantly being regenerated, in natural, fluctuating cycles.
No it is not.
No, they are made by polyps, which confusingly are also known as coral (but coral the reef is made of and the polyps are two different things).
