The Disconformity shows physical signs that uplift and erosion has occurred but bedding is parallel on both sides of the contact. In this step deposition stops and the beds are tilted and faulted. The picture shown in the sketch doesn't let me tell whether the faulting occurred before the tilting or vice versa . In this step the faulted, tilted beds are uplifted. Erosion occurs at the top of the picture.
Material is removed from the top down and carried away from the picture area.
Uplift keeps lifting the pile into the erosion zone at the earth's surface. Note that several of the younger beds have been lost. Such irregularity is common but there are cases where erosion has produced a flat surface. The presence of erosion strongly implies that uplift occurred. New sediments shown in red at the top of the picture bury the old erosion surface and the strata below it.
