Geologists study the earth's history, composition, physical structure and substance. They concentrate their time on rock formation; figuring out how rocks were formed, as well as studying the evolution of life on earth, examining fossils from both plants and animals. Geologists also study physical activities occurring above and below the earth's surface, many relating to earthquakes.

Geologists often work for companies searching for natural resources, including petroleum, water and metal companies. They may also seek positions teaching at the college or university level, or focus their time on geological research. If you are interested in pursuing a career in geology, this page provides information on how to become a geologist.

Geologists spend their time studying rock and mineral formation as it relates to the earth. They examine the evolution of life forms on earth, including plant and animal fossils, and study activities happening above and below the earth's surface, usually associated with earthquakes. These studies may include:

1. Gas exploration
2. Drilling
3. Water issues
4. Mapping
5. Exploration

Aspiring geologists should begin preparing for their careers as early as possible, taking classes in high school and college that will pave the way for more specific geological courses. These classes include, but are not limited to:

1. Physics
2. Chemistry
3. Physical Science
4. Earth Science
5. Biology
6. Environmental Science

If you are seeking a job outside of the education or research field, such as working for a company in the private sector, you will likely only need to obtain a bachelor's degree to enter the work field in an entry-level position. However, a master's degree is always helpful in making yourself more appealing to a potential employer. If you decide to become a college or university professor, or want to explore the field of geological research, you will likely need your Phd.http://degreedirectory.org/articles/Geology_How_to_Become_a_Geologist_in_5_Steps.html

Courses you can expect to take for your undergraduate degree in geology may include:

1. Marine geology
2. Hydrogeology
3. Paleoecology
4. Aqueous Geochemistry
5. Natural Hazards

Taking such courses will also help you chose a specialization in field to maintain your focus. Specialization may include mineralogy, marine geology, chemistry, hydrology, hazardous waste management, cartography, paleontology and physics.http://www.howtodothings.com/careers/how-to-become-a-geologist

If you are seeking employment in the private sector, you will likely need to obtain a license. Each state will have different requirements regarding licensing, so check the state you intend to work in for additional information. Licensing usually combines educational requirements, experience in the field and passing an exam.http://degreedirectory.org/articles/Geology_How_to_Become_a_Geologist_in_5_Steps.html
