Grade 5CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

•

Origin: The River Godavari originates from the Brahmagiri Hills at Trimbakeshwar in the Nashik district of Maharashtra.

•

Dakshina Ganga: Due to its large size and importance, the Godavari is often referred to as the 'Dakshina Ganga' (Ganges of the South).

•

Length: It is the second longest river in India with a total length of approximately 1465 km1465 \text{ km}.

•

Course of the River: It flows eastward across the Deccan Plateau, passing through the states of Maharashtra, Telangana, Andhra Pradesh, Chhattisgarh, and Odisha.

•

Tributaries: Major rivers that join the Godavari include the Purna, Wardha, Pranhita, Manjira, Wainganga, and Indravati.

•

Mouth and Delta: Before entering the Bay of Bengal, the river splits into two main distributaries, the Gautami and Vasishta, forming a large fertile delta region.

•

Dams and Projects: Significant structures like the Jayakwadi Dam (Maharashtra) and the Polavaram Project (Andhra Pradesh) help in irrigation and power generation.

•

Catchment Area: The Godavari basin extends over an area of approximately 3,12,812 km23,12,812 \text{ km}^2, which is nearly 9.5%9.5\% of the total geographical area of India.

💡Examples

Problem 1:

If the River Ganga is 2525 km2525 \text{ km} long and the River Godavari is 1465 km1465 \text{ km} long, calculate how much longer the Ganga is than the Godavari using vertical subtraction.

Solution:

2525−14651060\begin{array}{r} 2525 \\ -1465 \\ \hline 1060 \end{array}

Explanation:

To find the difference in length, we subtract the length of the Godavari (1465 km1465 \text{ km}) from the length of the Ganga (2525 km2525 \text{ km}), resulting in a difference of 1060 km1060 \text{ km}.

Problem 2:

The Godavari basin covers 312,812 km2312,812 \text{ km}^2 and the Krishna basin covers 258,948 km2258,948 \text{ km}^2. What is the combined area of these two river basins?

Solution:

312812+258948571760\begin{array}{r} 312812 \\ +258948 \\ \hline 571760 \end{array}

Explanation:

By adding the area of the Godavari basin (312,812 km2312,812 \text{ km}^2) and the Krishna basin (258,948 km2258,948 \text{ km}^2), we get a total combined area of 571,760 km2571,760 \text{ km}^2.
