Final answer:
An arete is a sharp bedrock ridge that separates two bowl-shaped depressions formed by mountain glaciers.
Step-by-step explanation:
A sharp bedrock ridge separating two bowl-shaped depressions formed by mountain glaciers is termed a arete. An arete is a narrow, steep-sided ridge that is formed when glaciers erode parallel valleys on opposite sides of a mountain. As the glaciers move down the slopes, they carve away the rock on both sides, creating a sharp edge in the center.
