This image has currency in it to indicate scale.

Using coins for scale is discouraged as it will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins can also reinforce a geographical bias, and some coins' designs are copyrighted.

Ideally, a photograph should include a ruler with the subject (example) or an added scale marking. SI ("metric") units are the most commonly used worldwide (see meter and centimeter).

Description
Deutsch: Kalktuff; frisches Wachstum am Albtrauf, Schwäbische Alb. Die Assimilation von Moos erhöht die Ausfällung von Calciumhydrogencarbonat aus dem Karstwasser einer Schichtquelle. Auf dem verkrusteten Moosgerüst wächst frisches Moos nach. Es entwickelt sich ein nach vorne und oben wachsendes, fragiles Gebilde.
Kalktuff gehört zur Gruppe der Sinter.
English: Fresh Kalktuff („Calcarious Tuff") - a rare secondary deposit of solid calcium carbonate on the Swabian Alb and the Franconian Jura, southern Germany. Assimilation of Moss accelerates chemical precipitation of calcium bicarbonate, which is dissoluted in karst water. The moss grows freshly on top of its encrusted species. These iterations form fragile structures.
