Please give me answer. ​

Answer 1

Got home and did some research, to learn that these are “oxbow" lakes. They owe their existence to the river that runs nearby. Here’s how: especially in the plains, rivers never run in straight lines. (Pretty much nothing in nature forms straight lines, in any case). They form curve after curve, and the flow of water itself makes those curves get more curvy. Imagine a section of the river that’s shaped like a shallow “S". Over time, the “S" gets deeper; the two tongues of land that it marks out get more pinched at their waists; eventually the river breaks through at the waist and takes the shorter, straighter path. If you picture this in your mind, you will see that what’s left after the breakthrough are these “C"-shaped bits of water: oxbow lakes.
