Answer:
the process or industry of obtaining minerals from a mine.
Explanation:
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized commodity that is of economic interest to the miner.
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 any material that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines.

Answer:
In matrilineal systems, inheritance of property and position usually is traced from the maternal uncle (mother’s brother) to his nephew (mother’s son) and, in some cases, mothers may pass on their property to daughters.
Explanation:
In matrilineal systems, women receive titles and names from their mothers, and later transfer them to their own daughters. But matrilineal succession is not necessarily related to women holding power, capital and titles. In some occasions, mothers pass these properties and titles to their sons, who later on repeat the process with their sister's children.
