Normal faults generally occur in places where the lithosphere is being stretched. Consequently they are the chief structural components of many sedimentary rift basins (e.g. the North Sea) where they have major significance for hydrocarbon exploration.

Normal faults extend the crust in a direction perpendicular to the fault trace. Because the hangingwall moves downward, normal faults place younger rocks ...

Scientists identify four types of faults, characterized by the position of the fault plane, ... In a normal fault (see animation below), the fault plane is nearly vertical. The hanging wall, the block of rock positioned above the plane, pushes down across the footwall, which is the block of rock below the plane.

First, for closely spaced normal faults, an array of parallel-dipping faults minimizes the viscous work rate (dissipation) in the viscous layer as it minimizes the distance between sources and sinks in the flow pattern.
