Analogy — Substance contained by a natural formation: Ocean : Water :: Glacier : ?

Introduction / Context:
The first pair is container→content: an ocean is a mass of water. A glacier is a large persistent body of what substance?

Given Data / Assumptions:

• Ocean contains water.
• Glacier is composed of compacted snow that becomes ice.

Concept / Approach:
Maintain the same container→content relationship.

Step-by-Step Solution:

Why Other Options Are Wrong:

• Cooling: process, not substance.
• Cave: a geological feature, not glacier’s content.
• Mountain: location/landform; not the substance of a glacier.
• None of these: incorrect as “Ice” fits.

Common Pitfalls:
Confusing origin (snow) with final consolidated material (ice). The analogy prefers the consolidated substance.

Final Answer:
Ice
