Class 5 Evs - WEST-BENGAL
Journey of a River
The chapter Journey of a River in the West Bengal Board (WBBSE) Class 5 EVS textbook, Our Wondrous World, takes young learners on a fascinating adventure from a high mountain peak all the way to the deep blue sea. Students discover how small streams join together to form a mighty river, learning about its three distinct stages: the upper course, middle course, and lower course. This chapter is very important for board exams as it builds foundational geographical concepts about water bodies, riverbanks, and human dependence on water, frequently appearing in both short answers and descriptive question papers.

Source of a River
The starting point of a river, usually found high up in the mountains where snow melts or rain collects to form a tiny stream.
Three Stages of a River
A river flows through three main stages on its journey: the upper course (youthful and fast in mountains), middle course (wider in plains), and lower course (slow and wide near the sea).
Tributary
A smaller stream or river that flows into and joins a larger main river along its journey.
Delta
A triangular area of land formed by silt and mud deposited at the mouth of a river just before it enters the sea, like the Sundarbans.
Mouth of a River
The final point of a river's journey where it empties its water into a larger body of water like a sea or ocean.

Frequently Asked Questions
Where do rivers usually start their journey?
Rivers usually start high up in the mountains where snow melts or rainwater gathers to form small springs and streams.
What is the difference between a tributary and a distributary?
A tributary is a small river that joins a bigger main river, whereas a distributary is a smaller stream that branches off from the main river before it meets the sea.
Why is the water in the lower course of a river often muddy?
As a river flows through its long journey, it carries a lot of soil, sand, and rocks (silt). By the time it reaches the lower course, the flow becomes slow and this heavy load of sediments makes the water look muddy.
