Explanation: Goa, a state in western India, is known for its diverse geography, which includes several rivers that are integral to its landscape and economy. Among these rivers, the Mandovi River stands out as one of the most significant. The Mandovi River is a major waterway in Goa, flowing through the heart of the state and contributing to its natural beauty and agricultural productivity.
The Mandovi River originates in the Western Ghats and flows through the districts of North Goa and South Goa before merging with the Zuari River to form the Mandovi-Zuari estuary. This estuary is a crucial part of Goa's ecosystem, supporting a variety of flora and fauna. The river is also important for transportation and irrigation, providing a vital water source for the agricultural activities in the region.
Understanding the geography of Goa is essential for comprehending the state's natural resources and the role of its rivers in supporting its economy and environment. The Mandovi River, being one of the major rivers in Goa, plays a significant role in the state's geography and is a key feature that distinguishes Goa from other states in India.
It is important to note that while Goa is a small state, it has a rich geography that includes several rivers, each contributing to its unique landscape. The Mandovi River, in particular, is a prominent feature that students should be familiar with when studying the geography of Goa. This knowledge is crucial for various competitive examinations, including the UPSC and state PSC exams, where questions on the geography of Indian states are common.
In conclusion, the Mandovi River is the correct answer as it is one of the major rivers in Goa, playing a significant role in the state's geography and economy. The other options listed (Mahanadi, Mahananda, and Manas) are rivers located in different parts of India and are not related to the geography of Goa.
