Anticlines and synclines - terms used to portray folds in view of the relative times of collapsed shake layers. A syncline is a crease in which the most youthful rocks happen in the center of an overlay, while the most established rocks happen in the center of an anticline. 

Monoclines - is a stage like a crease in shake strata comprising a zone of more extreme plunge inside a generally flat or delicately plunging grouping. 

Domes and basins - Dome structures are found where drives profound under the outside layer have pushed a part of the earth upward. The cuestas or covering folds confront internally. Basins are comparative, with the exception of the covers confront outward as the structure frames a gloom.
