Explanations:Harike Pattan, also known as Harike Wetland, is a significant ecological area located in the Tarn Taran district of Punjab, India. It is formed by the confluence of two major rivers: the Bias and the Satluj. The Bias river is a tributary of the Satluj, and their meeting point creates this important wetland area.
The Satluj, also known as the Sutlej, is one of the five major rivers of Punjab. It originates from the Mansarovar Lake in Tibet and flows through the Himalayas before entering India. The Bias river, on the other hand, is a smaller river that originates in the Shivalik Hills and joins the Satluj at Harike Pattan.
The confluence of these two rivers creates a unique ecosystem that supports a diverse range of flora and fauna. Harike Pattan is recognized as an important bird sanctuary and is home to numerous species of migratory birds. The wetland also plays a crucial role in the local agriculture and water supply.
It is important to note that while the Satluj is a major river in Punjab, it does not form Harike Pattan with the Ravi or the Gagher. The Ravi merges with the Satluj further downstream, and the Gagher is not involved in the formation of Harike Pattan. Therefore, the correct answer is that Harike Pattan is formed by the Bias and Satluj rivers.
