Explain the valleys formed by tectonic events.

1.	Explain the valleys formed by tectonic events.
Answer» The valleys formed by movements caused due to endogenetic forces come under the category of tectonics. This type of valley is classified into two parts: 1. Synclinal Valley 2. Rift Valley. 1. Synclinal Valley: Curved folds occurred in rocks due to compression force of tectonic action, which causes anticline and syncline. Synclinal valley is formed in subsided part of the folding. 2. Rift Valley: Rift Valley is a steep – sided valley formed by the downward displacement of a block of the earth’s surface between two nearly parallel faults. Valley of Narmada River is an example of rift valley.
