A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
The following outline is provided as an overview of and topical guide to geology: . 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 goal of this department is to conduct research in geology, mapping, hydrology, biology, and related sciences; evaluate hazards associated with floods, droughts, hurricanes, subsidence, human activity, and climate change; map the onshore and offshore geologic framework; assess mineral resources and develop techniques for their discovery ...
Environmental geology, like hydrogeology, is an applied science concerned with the practical application of the principles of geology in the solving of environmental problems created by man. It is a multidisciplinary field that is closely related to engineering geology and, to a lesser extent, to environmental geography . [ 1 ]
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.

This was an important step in further promoting knowledge of geology as a science and in recognizing the value of widely disseminating such knowledge. By the 1770s, chemistry was starting to play a pivotal role in the theoretical foundation of geology and two opposite theories with committed followers emerged.
Isotope geochemistry is an aspect of geology based upon the study of natural variations in the relative abundances of isotopes of various elements.Variations in isotopic abundance are measured by isotope-ratio mass spectrometry, and can reveal information about the ages and origins of rock, air or water bodies, or processes of mixing between them.
