Geology

Geology is one of the core stem subjects and a Bachelor's degree will be required at the very minimum for most jobs. In some states and for some jobs (especially where safety issues are concerned - such as in mines) certification may be required to practice. This should not be the case in the overwhelming majority of cases.
Most major colleges and universities offer geology degrees, so you should not struggle to find a relevant course. Even, these are not available at your chosen college, geography or other earth sciences are the preferred options. Students should take minors in mathematics and physics or other earth science options, and IT related subjects. GIS is one example of a growing and required IT skill in geology.
Although, there is a skills shortage, students are advised to study Master's degrees due to the applied science and project work that this would entail. Employers prefer graduates with work experience in their chosen field. Summer schools during Bachelor's degrees are useful too. Doctorates are useful for those, who want to pursue a career in academia, teaching, research or both. They are also advantageous for senior positions such as government advisory roles.
