The facts on the card
The card carries these facts from its Wikipedia article.
- Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology.
- Igneous and metamorphic petrology are commonly taught together because both make heavy use of chemistry, chemical methods, and phase diagrams.
- Sedimentary petrology is commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Petrology article was read about 19,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 52 and blocks with 25: each hit it takes is cut by 10 %.
