Rock relative dating to determine fault
Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change.Geology also plays a role in geotechnical engineering and is a major academic discipline.Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates.
It is also being subducted far to the northwest into the Aleutian Trench.
Geology is the scientific study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them.
The Greek derivation of the word "geology" refers only to the Earth, but since the beginning of the space age, the field has expanded to include the study of the solid matter of other celestial bodies, such as Mars and the Moon.
However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.
So, we rely on radiometric dating to calculate their ages.
