Rift valleys are long trench-like valleys formed due to continent-continent divergence.

FORMATION OF RIFT VALLEYS
- Continent based divergence of Tectonic Plates
- Role of mantle plumes (energy source)
In next stage; Rift valley turns into narrow sea as water (ocean) incursion takes place [or fresh] [not necessary] ex: Red sea
In the final stage; it becomes ocean. Ex: Atlantic ocean.
II. Geomorphological Significance
(1) Proves the Plate Tectonic Theory by McKenzie & Parker. (2) Helps to understand mantle plumes and volcanism. (3) Critical insights about Earth's interior and resource potential. (4) Helps to pre-plan and mitigate disaster threats. (5) Development of landforms like inudation valleys, etc. (6) Helps in riverine development Ex: Narmada, Tapi. (7) Helps us understand about solar system (esp. Inner planets)
III. Economic Significance
(1) Determines the patterns of settlements and habitation. (2) Easier for mineral extraction as ground is exposed. (3) Development of inland waterways potential. (4) Impact on livelihood patterns. (5) Migration (often forced). (6) Poverty and geoeconomic disputes (Bilateral, etc).
