About Online PhD Programs in Geological Science
Along with a geological science PhD students usually choose a concentration, such as environmental science, geodynamics, climatology, marine geology, solid earth geophysics, tectonics, and a myriad of others to study. In these concentrations, students can focus their research and analysis on particular subjects relating to that concentration. Students entering a geological science Ph.D. program with their bachelor's degree usually take about 5.5-6 years to finish their geological science doctorates. Those who already have their master's degrees generally finish sooner.

During their first year in a geological science program, Ph.D. students will begin to search, prepare, and defend possible research proposal topics. The intent of this process is to determine whether or not a student is passionate and engaged enough with their proposed research topic. After the first year of Ph.D. work, students will finalize their dissertation topic and present it to a committee. During the course of their Ph.D. work, students will present new findings and/or important updates on their research and analyses to professors and graduate committees. Before a student can graduate from a geological science PhD program, they must pass a comprehensive examination. A dissertation typically requires 5 years of research.
Value and Criticisms of a PhD in Geological Science
Those who pursue a geoscience PhD have a direct hand in solving some of the most puzzling mysteries and difficult challenges in modern environmental issues; therefore, their work is very creatively and philanthropically rewarding. Yet due to the fact that the public-at-large doesn't understand the gravity of the world's drastic environmental changes in recent years, it is hard to make any real change in the way the environment is treated through legislation and policy change nowadays. This can make it quite difficult to believe in the power of research and analysis while pursuing a geological science PhD degree.
Another drawback of obtaining a geological science PhD is the need to understand an array of science-related topics, including but not limited to physics, geology, chemistry, mathematics, engineering, and a myriad of others. Therefore, it is important to analyze whether or not you can comprehend these topics before you apply to a Ph.D. program. Lastly, the earth is experiencing a number of dwindling energy, mineral, and water resources along with concerns about environment and natural hazards, and these occurrences have presented some serious challenges to geoscientists. Consider all the pros and cons before deciding whether or not you want to pursue a geological sciencePhD
Application & Admission Requirements
Different schools have different requirements, but generally, students must have a least a master's degree in geology, earth sciences, environmental sciences, environmental policy & sustainability, engineering, ecology, forestry, planetary science, or a closely related field before they can be admitted to a geological sciences PhD program. Most schools also require their applicants to have at least a 3.0 cumulative GPA on a 4.0 scale. GRE test scores, letters of recommendation, personal statements, and a handful of other items are taken into consideration as well.
Career Options & Job Market
Students who graduate with a geological science PhD can enter an array of professions, including geoscientists, geologists, hydrologists, geological consultants, soil scientists, and numerous other careers.
