Maankuorissa
Maankuorissa is a Finnish term used in geology to refer to processes, rocks, and phenomena that occur within the Earth's crust. The crust is the outermost solid shell of the planet and differs from the mantle beneath it in composition, thickness, and geologic activity. Continental crust is typically about 30 to 50 kilometers thick, while oceanic crust is thinner, roughly 5 to 10 kilometers. The crust forms the surface on which continents and ocean basins sit and hosts much of the planet’s mineral resources.
The crust comprises a variety of rock types, including granitic, granodioritic, and other felsic rocks in continental
Geological processes within maankuorissa include crustal magmatism, earthquakes generated by brittle deformation, and hydrothermal activity that
In scientific usage, maankuorissa helps distinguish observations tied specifically to the crust from those related to
