Q1) What is a rift valley?

A rift valley is a huge fracture on continental and oceanic plates which widens gradually over extensive periods of times. A rift valley is a landform whose formation is triggered by a geologic rift or fault. The landform manifests as an elongated lowland in the middle of mountain ranges or several highlands. The depressed regions of a rift valley are created by one or more grabens. A graben is a valley having faults of two or more sides set up by the divergence of tectonic plates.
