Though Hutton believed in uniformitarianism, the idea was not widely accepted at the time. For an aspiring geologist, training typically includes significant coursework in physics, mathematics, and chemistry, in addition to classes offered through the geology department; historical and physical geology, igneous and metamorphic petrology and petrography, hydrogeology , sedimentology , stratigraphy , mineralogy , palaeontology , physical geography and structural geology are among the many required areas of study.

Most geologists also need skills in GIS and other mapping techniques. Geology students often spend portions of the year, especially the summer though sometimes during a January term, living and working under field conditions with faculty members often referred to as "field camp".

Many non-geologists often take geology courses or have expertise in geology that they find valuable to their fields; this is common in the fields of geography , engineering , chemistry , urban planning , environmental studies , among others.

Geologists may concentrate their studies or research in one or more of the following disciplines:. Professional geologists work for a wide range of government agencies, private firms, and non-profit and academic institutions.

They are usually hired on a contract basis or hold permanent positions within private firms or official agencies such as the United States Geologic Survey.

Local, state, and national governments hire geologists to work on geological projects that are of interest to the public community.

The investigation of a country's natural resources is often a key role when working for government institutions; the work of the geologist in this field can be made publicly available to help the community make more informed decisions related to the exploitation of resources, management of the environment and the safety of critical infrastructure - all of which is expected to bring greater wellbeing to the country.

An engineering geologist is employed to investigate geologic hazards and geologic constraints for the planning, design and construction of public and private engineering projects, forensic and post-mortem studies, and environmental impact analysis.

Exploration geologists use all aspects of geology and geophysics to locate and study natural resources. In many countries or U. Petroleum and mining companies use mudloggers , and large-scale land developers use the skills of geologists and engineering geologists to help them locate oil and minerals, adapt to local features such as karst topography or earthquake risk, and comply with environmental regulations.

Geologists in academia usually hold an advanced degree in a specialized area within their geological discipline and are employed by universities.

In Canada, National Instrument requires reports containing estimates of mineral resources and reserves to be prepared by, or under the supervision of, a Qualified Person QP who has at least five years of experience with the reported minerals and is a member of a professional association.

The QP accepts personal liability for the professional quality of the report and underlying work. The rules and guidelines codified in National Instrument were introduced after a scandal in where Bre-X geologists salted drill core samples at a gold exploration property in Busang, Indonesia.

The falsified drilling results misled Bre-X investors and upon discovery of the fraud, the company collapsed in the largest gold mining scam in history.

From Wikipedia, the free encyclopedia. Sir Charles Lyell first published his famous book, Principles of Geology , [72] in This book, which influenced the thought of Charles Darwin , successfully promoted the doctrine of uniformitarianism.

This theory states that slow geological processes have occurred throughout the Earth's history and are still occurring today. In contrast, catastrophism is the theory that Earth's features formed in single, catastrophic events and remained unchanged thereafter.

Though Hutton believed in uniformitarianism, the idea was not widely accepted at the time. Much of 19th-century geology revolved around the question of the Earth's exact age.

Estimates varied from a few hundred thousand to billions of years. The awareness of this vast amount of time opened the door to new theories about the processes that shaped the planet.

Some of the most significant advances in 20th-century geology have been the development of the theory of plate tectonics in the s and the refinement of estimates of the planet's age.

Plate tectonics theory arose from two separate geological observations: seafloor spreading and continental drift. The theory revolutionized the Earth sciences.

Today the Earth is known to be approximately 4. From Wikipedia, the free encyclopedia. Not to be confused with Geography. For the scientific journal, see Geology journal.

All geologists prepare reports, do calculations and use computers. The advanced degrees provide a higher level of training, often in a geology specialty area such as paleontology, mineralogy, hydrology, or volcanology.

Advanced degrees will often qualify the geologist for supervisory positions, research assignments, or teaching positions at the university level.

These are some of the most sought-after jobs in the field of geology. Employment opportunities for geologists are very good.

Most geology graduates with a strong academic background and good grades have no trouble finding employment if they are willing to move to a location where work is available.

Over the next several years, the number of geology job openings is expected to exceed the number of students graduating from university geology programs.

If you are a pre-college student, you can prepare to become a geologist by doing well in all of your courses.

Science courses are especially important, but math, writing, and other disciplines are used by every geologist during every working day.

If you are considering college or graduate school, there are many universities that offer courses or programs in geology.

Visit the website of a school that offers a geology degree , get in touch with the geology department, let them know you are interested and make arrangements to visit the campus.

Don't be hesitant. Good schools and professors want to be contacted by interested students. What Is Geology? Article by: Hobart M.
