Under which condition does a crevasse splay form?
Answer and explanation
Correct answer: When a natural levee breaks and floodwater spreads sand and silt over the floodplain
A crevasse splay forms when a river’s natural levee or bank is breached during flooding. Water escapes rapidly onto the floodplain, loses energy, and deposits a small fan-shaped spread of sand, silt, and other sediment beside the breach. Option A describes this sequence. Sea-arch collapse, cirque erosion, and mushroom-rock formation are coastal, glacial, and aeolian processes, respectively.
