"Geologists broadly
study the properties and processes of Earth
and other terrestrial planets. Geologists
use a wide variety of methods to understand
the Earth's structure and evolution,
including fieldwork, rock
description, geophysical
techniques, chemical
analysis, physical
experiments,
and numerical
modelling.
In practical terms, geology is important for mineral and hydrocarbon exploration
and exploitation, evaluating water
resources,
understanding natural
hazards,
remediating environmental problems,
and providing insights into past climate
change.
Geology is a major academic
discipline,
and it is central to geological
engineering and
plays an important role in geotechnical
engineering."
