Bigint Data Type The Bigint data type represents an integer value. It can be stored in 8 bytes. Formula 2^(n-1) is the formula of the maximum value of a Bigint data type. In the preceding formula N is the size of the data type.

He suggested that a process he called sea-floor spreading continually adds new material to the ocean floor. In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them.Look at Figure 16 to see the process of sea-floor spreading.arry Hess, an American geologist, was one of the scientists who studied mid-ocean ridges. Hess carefully examined maps of the mid-ocean ridge system. Then he began to think about the ocean floor in relation to the problem of continental drift. Finally, he reached a startling conclusion: Maybe Wegener was right!
