When you have thick layers of rocks rebounding where pressure is released
The lined space is reserved for the loading and unloading of wheelchairs.
The formation of an exfoliation dome begins with sheeting, when large masses of igneous rock, particularly, granite, are exposed by erosion, concentric slabs begin to break loose, this process occurs in part because of the great reduction in pressure when the overlying rock is eroded away, a process called unloading, and accompanying this unloading, the outer layers expand more than the rock below and thus separate from the rock body. Continued weathering eventually causes the slabs to separate and spall off, creating exfoliation domes.
Frost Wedging- water expands when frozen. Unloading- rock expands and breaks. biological- animals and plants dig up rock.

In an air compressor, there are devices that automatically stops the compressor from compressing air. A mechanical unloader is sometimes installed in large air compressors such that air valves are open when the set pressure is attained. When this happens, the drive motor continues running but no air pressurre is pumped to the receiving tank during the unloading period. When the pressure in the tank is reduced to a set level, the air valves in the compressor automatically closes and air pressure is again developed, this called pressure loading. In many oinstances, compressors are contolled only by pressure switches to automatically stop the drive motor at a set pressure and restart at a lower pressure.

If your unloading an aircraft, you need to be as close as possible.
Most air compressors do not have a continuous load, as a result there is a need to control the amount of air entering the system. One way to allow for load swings is to let the air surge tank pressure float between two pressures. To do this you can either start and stop the compressor automatically to stay with in the required pressure range. Say pressure Pmin and Pmax. During normal requirement(load) of air, compressor will work at below Pmax.But when the requirement(load) decreases, delivery pressure start to increase. And when pressure equalise to Pmax,compressor start to unload(means pressure of the compressor start to decrease). During unloading air inlet valve is closed and delivery pressure decreases till it become equal to Pmin. Working of compressor in this phase is known as unloading. As soon as pressure become equal to Pmin compressor start to load again till it reaches Pmax. working of compressor in this phase is known as loading.
