berggrunninn
Berggrunninn is a geological term referring to the solid rock that lies beneath the loose surface materials such as soil, sand, and gravel. It forms the foundation of the Earth's crust.

In some areas, it may consist of ancient, hard metamorphic or igneous rocks that have been exposed through erosion or uplift. In other places, the berggrunninn can be composed of younger sedimentary rock layers.
Understanding the berggrunninn is crucial for various scientific and practical applications. Geologists study it to interpret
