The minimal education required for entering the field of geology is a four-year Bachelor's degree in Geology, combined with courses related to your specialization. In high school, you should prepare for the scientific and mathematical rigour of the geology course-load by focusing on those two disciplines, writing, computers, geography, and public communication. These skills, along with a persona dedication, are essential for success as a geologist.
After undergraduate school, many geologists continue on in education to pursue Master's Degrees and Doctorate Degrees in various areas of specialization. These include paleontology, mineralogy, volcanology, or hydrology. Employment opportunity for geologists is very high; getting good grades and a strong academic background will usually allow you to find a job very easily.
Since geology deals with much fieldwork, you should be able to adapt to weather changes and to varying terrains. Therefore, real passion is required to work successfully within the first few years of research. Effective communication of your findings is vital for advancing your position in the scientific community as well. This requires you to have a high level of perseverance and interest in your discipline.
