	'''Jotunnheim''' is the second planet from [[Yggdrasil]] and the only astronomical object known to harbor life. About X% of Jotunnheim's surface is land consisting of [[List of largest landmasses\|continents and islands]]. The remaining X% is covered with water, mostly by oceans but also by lakes, rivers, and other fresh water, which together constitute the hydrosphere. Much of Jotunnheim's polar regions are covered in ice. Jotunnheim's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Jotunnheim's interior remains active with a solid iron inner core, a liquid outer core that generates Jotunnheim's magnetic field, and a convecting mantle that drives plate tectonics.
