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.

Sea-floor spreading occurs where oceanic plates are diverging from one another. Plates are huge slabs into which the crust as well as the upper part of the mantle (the intermediate zones between the Earthâs crust and core) is divided.As the plates move apart, the rocks break and form a crack between the plates.agma is a very hot, molten rock which is formed within the earth by partial melting of the mantle. As a result, the age of the rocks increases as one move away from the rift-zone (place where the earthâs crust is pulled apart). The mid-oceanic ridge is the primary site for sea-floor spreading.
