Why do some waterfalls have multiple tiers?
Quick Answer
Tiered waterfalls form where a river crosses layers of rock with different hardness, creating a series of steps instead of one drop.
The Full Story
If a river flows over alternating layers of hard and soft rock, the softer layers erode faster. That can create a staircase-like profile with several ledges. Water may drop from one level to the next, forming a tiered waterfall. Glacial erosion and faults can also produce stepped terrain. These waterfalls can be especially dramatic because each tier reflects a different stage of rock erosion.
