Journey of a River
The chapter Journey of a River in the Class 5 EVS curriculum for Punjab (PSEB) explores the fascinating life cycle of a river from its origin in high mountains to its final meeting point in the sea. Students learn about the three main stages of a river's journey: the upper course (youth), middle course (maturity), and lower course (old age). The chapter highlights how rivers shape the landscape through erosion and deposition, provide essential water for drinking and irrigation in Punjab's fertile plains, and sustain diverse ecosystems. Understanding this journey is vital for board exams as it builds foundational knowledge about water conservation, local geography, and environmental science.

Origin of a River
Rivers usually start high up in the mountains from melting snow, glaciers, or underground springs where they flow very fast.
Stages of a River
A river travels through three stages: the upper course in mountains, the middle course in plains, and the lower course where it flows into the sea.
Tributary and Estuary/Delta
Smaller streams that join the main river are called tributaries, while the triangular deposition of silt formed at the mouth of a river before it meets the sea is a delta.
River Pollution
Human activities like dumping waste, washing clothes, and releasing factory chemicals into rivers make the water dirty and harm aquatic life.
Importance of Rivers in Punjab
Rivers like the Sutlej, Beas, and Ravi provide water for farming, making Punjab the 'granary of India', and are crucial for daily life.
