A geologist is a scientist who studies the structure, composition, and history of Earth. Geologists incorporate techniques from physics, chemistry, biology, mathematics, and geography to perform research in the field and the laboratory. Geologists work in the energy and mining sectors to exploit natural resources.
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

Geology – one of the Earth sciences – is the study of the Earth, with the general exclusion of present-day life, flow within the ocean, and the atmosphere. The field of geology encompasses the composition, structure, physical properties, and history of Earth's components, and the processes by which it is shaped.
The branch of geology and mineralogy that studies natural and artificial gemstones. gemstone. Also called a gem, fine gem, jewel, precious stone, or semi-precious stone. geogenic Of geologic origin – Resulting from naturally occurring geological processes. geologic map A special-purpose map made to show geological features. geological time scale
Photogeochemistry is the study of light-induced chemical reactions that occur or may occur among natural components of the Earth's surface. [ 14 ] Regional geochemistry includes applications to environmental, hydrological and mineral exploration studies.
It incorporates astronomy, mathematical geography, meteorology, climatology, geology, geomorphology, biology, biogeography, pedology, and soils geography. Physical geography is distinct from human geography, which studies the human populations on Earth, though it does include human effects on the environment. [29]
Geoscientist may refer to: . Geoscientist, a person studying Earth or other planets using Earth science. Geochemist (see Geochemistry); Geologist, a scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth and other terrestrial planets
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .
