In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. Minerals are classified by key chemical constituents; the two dominant systems are the Dana classification and the Strunz classification. Silicate minerals comprise approximately 90% of the Earth's crust. Other important mineral groups include the native elements, sulfides, oxides, halides, carbonates, sulfates, and phosphates. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.

The northern region of Europe has several definitions. Narrower definitions may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54°N, or may be based on other geographical factors such as climate and ecology. A broader definition would include the area of Europe north of the Alps (but excluding Eastern Europe). There are various definitions of Northern Europe which often include the British Isles, the Nordic countries and the Baltic states and sometimes Greenland, northern Germany, northern Belarus and northwest Russia. country in Northern Europe - Aland Islands, Channel Islands (Guernsey, Jersey, Sark), Denmark, Estonia, Faroe Islands, Finland, Iceland, Ireland, Isle of Man, Latvia, Lithuania, Norway, Svalbard & Jan Mayen Islands, Sweden, United Kingdom of Great Britain & Northern Island.
