Which outcome occurs when a meander stream encounters a resistant rock layer during downcutting?

💡 Explanation

Entrenched meanders develop, because the downcutting stream maintains its course while encountering resistance, which creates incised loops where the *downcutting erosion* mechanism happens; therefore the stream erodes vertically, rather than laterally forming braided channels or oxbows.

• Which outcome occurs when prolonged aeolian processes erode surface materials?
• Which mechanism reduces ocean gyre intensity following heightened glacial meltwater discharge?
• Which downstream effect of prolonged high-volume flows typically initiates alluvial fan stream incision?
• Which climatic effect results because mountain ranges force air masses upwards in many global climate regions?
• Which long-term outcome happens when intense *bioturbation* decreases topsoil density?
• After effusive lava eruptions decrease, which outcome results from increased dissolved silica content?
