What is a geologist?

A geologist is a scientist who studies the earth’s solid and liquid materials, like soil and rocks, and their processes. They’re significantly valuable within businesses, especially those involved in natural resource extraction and environmental consulting, as their understanding of the Earth’s processes can help companies safely execute their operations and align them with environmental regulations. Their findings influence society at large, providing essential insights for sustainable development.

Duties and responsibilities

The specific tasks of a geologist can vary depending on the area of expertise. Generally, they collect samples and data from the field, conduct laboratory tests, and analyze data using computer software.

Geologists also contribute to environmental conservation efforts by determining the impact of human activities on the Earth and its resources. They define remedial actions and help forecast future scenarios to guide strategic planning.

Work environment

Geologists are often required to split their time between the field, labs, and office environments. Depending on the terrain and weather, fieldwork can involve traveling to remote locations and working in challenging conditions.

Typical work hours

Most geologists work full-time and typically work a standard 40-hour per week. However, the nature of their work means that there may be periods of longer hours, especially when they are conducting field studies. Fieldwork may also require being away from home for extended periods, sometimes in remote locations, making for unusual work schedules.

How to become a geologist

The key steps typically include earning a bachelor’s degree, gaining hands-on experience, and meeting state licensure requirements.

Step 1: Earn a high school diploma

Your journey starts with obtaining your high school diploma. During these years, concentrate on science courses such as biology, chemistry, and physics, as well as math subjects.

Step 2: Obtain a bachelor’s degree

A bachelor’s degree in geology or a closely related field is the minimum education requirement for a professional working in this field. You will study subjects like physical geology, mineralogy, petrology, and earth dynamics.

Step 3: Complete an internship or co-op program

Hands-on experience is key in this profession, so seek to complete an internship or participate in a co-op program while pursuing your degree. You’ll apply the skills learned in your coursework and gain practical experience in the field. It also provides a fantastic opportunity for networking that can prove instrumental when you start job hunting after graduation.

Step 4: Obtain state licensure

After you have completed your undergraduate degree, you’ll want to ensure that you meet your state’s licensing requirements. Many states require geologists to obtain a license. This usually involves passing a standardized exam, along with proof of adequate academic education and field experience.

Step 5: Consider a master’s degree

While not required for all roles, some specialized fields within geology may require a master’s degree. If you’re considering a career in research or academia, a master’s or even a doctoral degree could be necessary. In this step, you’d go deeper into geology—allowing you to explore a certain area in detail.

Step 6: Apply for jobs or doctoral programs

After obtaining the necessary education and licensure, you are ready to apply for positions in the field. Keep an eye on job boards, network with industry professionals, and seek guidance from your school’s career services if available. Alternatively, if you see yourself in a research or teaching role, consider applying for doctoral programs in this step.
