Jog Falls, one of the highest waterfalls in India located in Karnataka, is formed on which river?

Introduction / Context:
Jog Falls is a famous waterfall in the state of Karnataka and is often highlighted in Indian geography for its height and scenic beauty. It is important to know on which river this waterfall occurs, as such questions connect specific physical features with their river systems.

Given Data / Assumptions:

• The waterfall in question is Jog Falls in Karnataka.
• The task is to identify the river that forms this waterfall.
• We assume the learner is familiar with major peninsular rivers and their locations.

Concept / Approach:
Jog Falls, also known as Gerosoppa Falls, is located on the Sharavati river in the Shivamogga district of Karnataka. The Sharavati is a west flowing river that drops in a series of steep falls at Jog, creating one of the tallest waterfalls in India. The Kaveri, Godavari, and Krishna rivers are also major peninsular rivers, but their well known waterfalls are different. Jog Falls is specifically associated with the Sharavati, not with the larger east flowing river systems.

Step-by-Step Solution:
Step 1: Recall that Jog Falls is in Karnataka and is one of the highest waterfalls in India. Step 2: Remember that the Sharavati river is a west flowing river in Karnataka that forms Jog Falls. Step 3: Compare this with the Kaveri river, which is associated with other waterfalls such as Shivanasamudra, not with Jog Falls. Step 4: Note that the Godavari and Krishna rivers have different courses and do not form Jog Falls. Step 5: Conclude that Sharavati river is the correct answer.

Verification / Alternative check:
Tourism and geography references consistently describe Jog Falls as situated on the Sharavati river. Maps that mark Jog Falls show it on this river in the Western Ghats region of Karnataka. The association is so strong that Sharavati and Jog Falls are often mentioned together in descriptions of Karnataka's natural attractions.

Why Other Options Are Wrong:

• Kaveri river: Known for the famous Shivanasamudra Falls, not Jog Falls.
• Godavari river: A major east flowing river of central and southern India, but not associated with Jog Falls in Karnataka.
• Krishna river: Another major peninsular river with its own dams and projects, but not the river that forms Jog Falls.

Common Pitfalls:
Students sometimes confuse Jog Falls with other waterfalls on the Kaveri river because both are in southern India. Others may simply pick a familiar major river like Godavari or Krishna without remembering the specific regional association. To avoid mistakes, link Jog Falls always with Sharavati and Shivanasamudra with Kaveri in your mental map of Indian waterfalls.

Final Answer:
Jog Falls in Karnataka is formed on the Sharavati river.
