2. What is the related disciplines?Geology, mineralogy, historical resource extraction, recreational prospecting
3. Why does gold stay at the bottom of the pan?Gold is very heavy—about 19 times heavier than sand. When you shake the pan, the heavy gold sinks to the bottom and the lighter sand goes over the lip.
4. Where can you find places to pan for gold?Good places to pan are spots where the river slows down, like inside bends, behind big rocks, or in cracks in the riverbed. These spots trap the heavy gold.

Alluvial environment: Areas, typically riverbeds, where sediments are deposited by flowing water.
Specific gravity: The ratio of the density of a substance to the density of a reference substance, usually water.
Hydraulic mining: A method of mining that uses high-pressure water jets to dislodge rock material and recover gold.
