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.

Subduction is the process that destroys oceanic crust, and sea-floor spreading is the process that creates oceanic crust. Sea-floor spreading is driven by crust formation along the mid-ocean ridges, meandering undersea mountain ranges that span Earth like the seams of a baseball.eafloor spreading Theory that explains how continental drift occurs. It proposes that the ocean floor is moved laterally as new basalt rock is injected along mid-ocean ridges, and so the ocean floor becomes older with increasing distance from the ridge.
