Correct answer: "Rivers wear away banks until the bank is broken and the river flows straight."
Explanation: As a meandering river erodes the outer banks and deposits sediment on the inner banks, the neck of a meander becomes narrower. Eventually the river cuts through the neck (often during a flood), creating a new, straighter channel. The abandoned meander loop becomes an oxbow lake.
