Editing Geocaching (section)

====EarthCache====
Similar to virtual geocaches, an Earth cache is published not by a local reviewer, but by a volunteer regional reviewer associated with the [[Geological Society of America]]. The geocacher usually has to perform a task which teaches an education lesson about the geology of the cache area.<ref>{{Cite web|url=https://www.geosociety.org/GSA/fieldexp/EarthCache/home.aspx|title=EarthCache|website=Geological Society of America|access-date=2 October 2022}}</ref><ref name="geo_types"/> Visitors must answer geological questions to complete the cache which can be as simple as describing the color and thickness of layers in an [[outcrop]] or can be as complicated as taking measurements of stream velocities or fault offsets. Earthcaches covers geologic topics such as: [[petrology|rock formation]], [[mineralogy]], [[geophysics|earthquakes]], [[fluvial processes]], [[erosion]], [[volcanology]], and [[planetary science]] (among others).
