Chapter 2 of Class 5 EVS (Our Wondrous World), Journey of a River, follows the real Godavari River from its source in the Western Ghats to the Bay of Bengal.
Key Concepts
Three stages of a river’s journey: the upper course (mountainous, where it begins as a stream), the middle course (tributaries join, the river widens), and the lower course (flowing slowly across plains to the sea).
Key vocabulary: source (where a river begins), tributary (a smaller river joining a larger one), mouth (where a river meets the sea).
The Godavari’s real path: begins at Trimbakeshwar in Maharashtra and flows through Maharashtra, Telangana, Chhattisgarh, and Andhra Pradesh before reaching the Bay of Bengal.
Quick Recap
- A river always flows from a higher source towards the sea, joined along the way by tributaries.
- Dams built on a river’s course can affect the natural flow and the areas downstream.
Common Mistake to Avoid
Confusing a tributary with the main river — a tributary is a smaller river that joins and adds its water to a larger one, not a separate, unrelated river.
Frequently Asked Questions
What is the difference between a river’s source and its mouth?
The source is where a river begins (often in hills or mountains); the mouth is where it finally meets the sea.
What problems can building a dam create?
It can change water flow to areas downstream and affect the people and ecosystems that depend on the river’s natural course.
