Sopwith Model XII: Mineral vein denudation
This model shows the influence of surface denudation and faulting on inclined strata, with increased complexity to the situation in Model VII

Sopwith Model VIII: Overcutting of strata
This model shows overcut strata: when the layers of rock are inclined at a gentler angle than the eroded slope, the resulting vee pattern points uphill

Sopwith Model X: Denuded basset of strata
This model shows undercut strata: when the layers of rock are inclined at a steeper angle than the eroded slope, the resulting vee pattern points downhill

Sopwith Model III: Dislocation of strata
This model represents the side of a valley of denudation, with undisturbed horizontal beds of sedimentary rock when fully assembled

Sopwith Model I: Stratified rocks / denudation
Black lines in this model represent coal seams, between lighter shales and sandstones. When separated the lower section shows a gently inclined valley floor
