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.
Latin America is the portion of the Americas comprising countries and regions where Romance languages—languages that derived from Latin—such as Spanish, Portuguese, and French are predominantly spoken. The term was originally used to refer to places in the Americas that were ruled under the Spanish, Portuguese, and French empires. Latin America consists of 20 countries and 14 dependent territories that cover an area that stretches from Mexico to Tierra del Fuego and includes much of the Caribbean. It has an area of approximately 19,197,000 km2 (7,412,000 sq mi), almost 13% of the Earth's land surface area. As of March 2, 2020, the population of Latin America and the Caribbean was estimated at more than 652 million, and in 2019, Latin America had a combined nominal GDP of US$5,188,250 million and a GDP PPP of US$10,284,588 million.
