geóideíhlutdar
A geóideíhlutdar, meaning "geoid island" in Icelandic, is a hypothetical landmass that floats above the Earth's surface without direct connection to the mantle or crust. This concept arises from theoretical considerations in geology and physics, exploring the potential for large, buoyant structures to exist in the Earth's gravitational field. The idea suggests that such a formation would be composed of materials less dense than the surrounding lithosphere, allowing it to maintain an elevated position.
The existence of geóideíhlutdar is not supported by current geological evidence. The processes that shape the
While geóideíhlutdar remain purely speculative, they touch upon principles relevant to understanding phenomena like mantle plumes
