Question
Describe the processes involved in the formation of the Rift valley by anticlinal arching.
Answer
What is Anticlinal Arching?
Anticlinal arching, in geology, refers to a geological structure characterized by an upward, convex arch or fold in rock layers. It is one of the fundamental types of geological folds, the other being synclinal folding, which features downward, concave folds.Formation of the Rift Valley by Anticlinal Arching
- Compressional forces act on crustal rocks- Crust is forced to bend upwards
- A large anticline is formed
- Continued compression create tension on the crust of anticline
- Several faults form on the anticline
- The side blocks are forced to upthrust
- Middle block left in leading to formation of rift valley.
