The characteristics of structural plains are-
- These plains are formed due to uplift or subsidence of land.
- Diastrophic forces may cause uplift of a portion of land beneath the ocean water or may cause submergence of coastal land under ocean water.
- For example- The Great Plains of USA were formed due to the uplift of land submerged under water while the Coromandal plains in India are a result of mild submergence followed by sedimentation.
