Geologist’s Hammer in Action: Rock Sampling and Field Testing #176605 (License: Personal Use)

This line drawing shows a standard geological hammer with a flat face and pointed pick end striking a weathered rock, sending small fragments airborne. The illustration emphasizes proper technique for breaking or splitting rocks during fieldwork, highlighting how percussion reveals internal structure, cleavage, and mineral grain. Such imagery is commonly used in educational materials to demonstrate basic field methods in earth sciences.

Used on geology education pages, field guidebooks, museum exhibits, or university course sites to illustrate rock sampling, hardness testing (e.g., Mohs scale), or野外 (field) methodology; matches user intent for learning practical geology skills or identifying tools.
