Which outcome occurs when glacial sediment blocks a valley, trapping meltwater?

💡 Explanation

A moraine dammed lake forms, via glacial deposition. The mechanism of **glacial till accumulation** blocks water flow. Therefore a lake occurs rather than a braided stream, because the sediment accumulation creates a basin rather than allowing water dispersion.

• Which resulting wind pattern occurs because thermal imbalances establish pressure gradients on a rotating Earth?
• Which risk increases significantly when low-silica lava erupts subglacially?
• Which outcome is accelerated when increased sediment deposition obstructs subduction zones?
• Which erosion risk increases where deep-rooted shrubland transitions to heavily grazed pasture?
• Which landform consequence occurs where freeze-thaw weathering is dominant?
• Which mineral deposition pattern indicates stable cave climate?
