A geologist is a kind of scientist that examines the processes that form the Earth and other terrestrial planets, as well as the solid, liquid, and gaseous materials that makes up Earth and the other terrestrial planets. Geologists often get their education in geology, although having a foundation in physics, chemistry, biology, or any of the other disciplines is helpful. Geology relies heavily on field study and field work; however, many subdisciplines also involve laboratory and digitalized work. Field research is an essential component of geology.
Geologists are employed in the mining and energy industries, where they look for natural resources such as precious and base metals, precious and natural gas, and petroleum. They are also at the vanguard of efforts to avoid and mitigate damage caused by natural hazards and catastrophes such as earthquakes, volcanoes, tsunamis, and landslides. They have been at the forefront of these efforts for quite some time. Their research is utilised to raise awareness among the general population about the possibility of these occurrences. Geologists are also key contributors to climate change talks.
