The facts on the card
The card carries these facts from its Wikipedia article.
- This layer is sometimes called sial because its bulk composition is richer in aluminium silicates and has a lower density compared to the oceanic crust, called sima which is richer in magnesium silicate minerals.
- Changes in seismic wave velocities have shown that at a certain depth, there is a reasonably sharp contrast between the more felsic upper continental crust and the lower continental crust, which is more mafic in character.
- Most continental crust is dry land above sea level.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Continental crust article was read about 43,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 41: each hit it takes is cut by 16 %.
How to get Continental crust
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
