In due course of time the meander loop cuts off from the river and forms a cut - off lake, also called a/an _________ lake.
ox - bow
In mature rivers, the neck of a meander loop narrows over time due to erosion on the outer bank and deposition on the inner bank. During a flood the river cuts straight across the neck, abandoning the loop, and deposition seals it off.
The crescent-shaped water body left behind resembles the bow of an ox's yoke and is therefore called an ox-bow lake. Oases occur in deserts, lagoons are coastal, and tectonic lakes form by crustal movement — none relate to meanders.
