Internal structure of Earth, an Uncommon card

The card carries these facts from its Wikipedia article.

• The primary structure is a series of layers: Its mechanical structure is of a rigid lithosphere, a semi-fluid asthenosphere, a semi-fluid mesosphere, a liquid outer core, and a solid, rigid inner core.
• Its chemical structure is of a silicate crust, a ferromagnesian mantle, and an iron-nickel core whose flowing upper portion generates the Earth's magnetic field.
• Scientific understanding of the internal structure of Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravitational and magnetic fields of Earth, and experiments with crystalline solids at…

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Internal structure of Earth article was read about 140,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 65: each hit it takes is cut by 26 %.
