Explanation: The Son River is a significant tributary of the Ganga River, playing a crucial role in the hydrological and ecological systems of central India. To understand the geography of the Son River, it is essential to know its origin, course, and confluence point.
The Son River originates in the Amarkantak Plateau, which is located in the Shahdol district of Madhya Pradesh. The Amarkantak Plateau is a significant geographical feature in central India, known for its rich biodiversity and historical significance. The plateau is also the source of several other important rivers, including the Narmada and the Mahanadi.
The Son River flows through the states of Madhya Pradesh and Uttar Pradesh before joining the Ganga River. It is approximately 785 kilometers long and is one of the major tributaries of the Ganga. The river flows in a generally eastward direction, passing through several important cities and towns, including Rewa, Mirzapur, and Sonbhadra.
The confluence of the Son River with the Ganga River occurs at Arrah, a town in the Bhojpur district of Bihar. This confluence is a significant geographical and cultural point, as it marks the merging of two important river systems in India.
It is important to note that the Son River joins the Ganga on the right bank, which is typically considered the south bank in this context. This is a common misconception, as some might assume that the Son River is a west bank tributary of the Ganga. However, the Son River flows from the west to the east and joins the Ganga on the right bank, making it a south bank tributary.
In summary, the Son River originates in the Amarkantak Plateau and joins the Ganga at Arrah, Bihar. These facts make Statements 2 and 3 correct, while Statement 1 is incorrect due to the misconception about the river's confluence point. Understanding the geographical details of rivers like the Son is crucial for comprehending the broader hydrological and ecological systems of a region.
