Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through

· Environmental impacts: Studying gneiss rocks helps understand how past environmental conditions influenced rock formation and how these processes impact the environment today. Rock layers : Gneiss rocks often exhibit distinct layering, known as foliation, which can indicate the direction of the pressure during their metamorphism.
