Sabarmati, Mahi, Narmada and Tapti rivers form:

Solution (By Examveda Team)

Sabarmati, Mahi, Narmada, and Tapti rivers are known for forming potholes. Potholes are natural depressions or cavities that are formed in the riverbeds due to the erosional action of flowing water carrying rocks and sediment. Over time, the swirling action of water, along with the abrasion caused by rocks and pebbles, creates these cylindrical or hemispherical cavities in the bedrock of the river. Potholes are a unique geological feature that can be found in various river systems around the world.
