Arrange the following geological/material terms from smallest particle to largest landform. 1. Stone 2. Sand 3. Rock 4. Boulder 5. Hill

Introduction / Context:
Material/landform ordering tests knowledge of relative scale from granular particles to macro relief features.

Given Data / Assumptions:

• Sand refers to small granules.
• Stone is a small piece of rock.
• Rock is the general consolidated mass.
• Boulder is a very large detached rock fragment.
• Hill is a prominent landform, larger than boulders.

Concept / Approach:
Order strictly by size/scale: particle → fragment → mass → very large fragment → landform.

Step-by-Step Solution:
2 Sand (smallest).1 Stone (pebble/stone scale).3 Rock (generic mass).4 Boulder (very large rock piece).5 Hill (macro landform).

Verification / Alternative check:
Each element is larger or more extensive than the previous.

Why Other Options Are Wrong:
Placing hill before sand is reversed; mixing stone/rock order ignores that stone is a piece of rock.

Common Pitfalls:
Equating “rock” with any size; the term is generic, but here we use common educational hierarchy.

Final Answer:
2, 1, 3, 4, 5
