Who is a Geologist?
Geologist or geoscientist is a scientist who studies the earth, about its origin, and what it is made up of. Geologist studies about the rocks, gases, and minerals found on the planet. And also how earthquakes, volcanoes, floods, and other natural phenomena have an impact on the earth's surface. A geologist understands earth and its inhabitants and provides useful information for the same. A geologist collects samples of rock and fossils, measures the physical properties of earth or study map & rock formation, and more depending on the geologist degree and specialization.

The most common question that comes into our mind is, where do Geologists work? And how much does a geologist make a year? Well, geology careers in demand because geologists can work for Local and they draw state Govt, Private Industries, Military Branches, Non-Profit Organizations, College and Universities, and Self Employed Consultants and the average annual salary is around $73,218 USD.

How can you become a geologist

Geology careers are in demand, and If you have the zeal to explore the earth's origin and everything related to earth, you have to opt for a bachelor's degree in geology or geoscience to become a geologist. The skills required to become a geologist are

Communication Skills- Geologists have to write reports and findings clearly so that it is easily understandable by their teammates and others who are not from the geology background.

Critical Thinking Skills
 Geologists should have the ability to observe and carefully analyze the data.

Problem Solving Skills
Geologists have to work on very complex and sensitive projects, and evaluating the statistical data. Finding the solution is one of the most important skills required.

What geologist do
There are different ranges of work and departments where geologists do work. Some geologists work in the field, and some work in the offices, and others work a mixture of field and office work. Geologists' work is to understand the earth's history and then predict how the events from the past influence the future. Here are examples to help you understand it better:

Geologists study Earth processes
 Geologists map those areas where natural calamities like floods, volcanic eruptions, earthquakes, cyclones, and landslides have occurred in the past. Investigate more about those areas, thereby making the maps that might be prone to natural calamities in the future.

Geologists study Earth materials
Researching the Earth materials is very important to locate the mines, underground water, petroleum, natural gas, etc. Earth is a reservoir of natural resources, and to locate them is the work of a Geologist.

Geologists study Earth history
The historical data about the earth helps geologists study the climate changes that have occurred because of past events and how they can affect the future. The study of how the climate has changed over time and what are the reasons behind the changes.

Let's understand the work of geologists better; below mentioned are some tasks performed by geologists in various fields and industries.

Mapping & fieldwork
This is field-based work where geologists need to do mapping of different aspects of the rock of a particular area.

Field Mapping
It is basically to produce a geological map by examining the area's rock type and geological structure and which helps to know how they relate to each other. It is generally taken care of by oil and gas companies or geoscientists who work for the universities or companies and students who study geology.

Geotechnical Mapping
It is to know the stability and properties around the rock areas. It helps determine whether the area is suitable or not for any construction or modification like building a tunnel or bridge.

It is a common practice done by geological companies and researchers.

Laboratory work
Many geologists work in laboratories, and they research and experiment a lot. We get to know many things about the geology of the earth and other planets with the help of geologists who work in labs. Laboratory-based work majorly done by those who work in geology based companies or work as researchers. Many commercial geology-based companies where geoscientists work specifically in laboratories are engineering, environmental, oil & gas, and mining.

Lab works include:
It is used to check very fine details of rock and fossils.

Geochemical analysis
It is used to disclose details about samples like how much quantity of metal content or oil and more. This work is done by using chemical methods.

Geomechanical test
It is used to test and disclose the strength of rocks.

Computer-Based Work
Geologists have to do much work on computers, and they need to work on specialized softwares. Geologists have to work in fields and offices, and file-based computer-related work has also become customary.

Geographical Information Systems (GIS)
It is a computerized Earth mapping system that helps capture, store, check, and display the earth's surface data. It provides the data to geologists for analyzing.

Database Management
One of the geologists' essential tasks is to keep the database updated with the relevant information, which is essential for modelling processes that help in better understanding.

Modelling programs
Geologists are trained to understand and learn how the processes and specialized softwares work.

Logging is a field-based activity based on geological drilling. Geologists understand and describe the rocks extracted by drills. To study past environmental changes or accurately record sample locations, logging of volcanic and sedimentary rocks is used.

Types of Logging includes:
Rock core logging
It is also known as rock chip logging that is used by mining and exploration companies.

Mud logging
Mud logging is for oil and gas exploration.

Geotechnical logging
It is used to know how strong and weak rocks are. It helps in identifying fractures.

Report Writing
Report writing includes summarizing all the tasks mentioned above. Geologists and geoscientists, who performed all the tasks mentioned earlier, are required to maintain the reports in a concise yet comprehensive manner. Reports can range from short daily site updates to large documents that include several hundred pages, such as drilling progress project reports, Ph.D. dissertations, etc.


Geology careers are in demand because it is an exciting and rewarding career option if you are interested in Earth sciences. Geologists work in mining and energy sectors, and they also help mitigate and prevent the damage caused by natural hazards. Geologists work in fields as well as laboratories so a Geologist will have experience of both worlds.
