Concept:A nodal town is a settlement that arises at the junction or meeting point of roads and other transport routes.
Explanation:Roads are important lines of transport and communication.
Where several roads converge, they create a central node.
At this node, people and goods gather and are exchanged.
This attracts traders, travellers, and service providers.
As a result, a settlement develops and later grows into a town.
A town that grows in this way is called a nodal town.

A confluence town is formed where two rivers meet.
A gap town develops at a natural break or pass through hills or mountains.
