I think this is part of why geology is considered an easy science . Memorizing rocks and minerals and formation sequences , etc . There ' s not a ton of quantitative stuff in the basics . It ' s when you start applying the knowledge though , to actual situations that it gets more mathy . Hydro , as mentioned , is all about fluid movement within the ground and uses a lot of calculus . Geophysics remote sensing are all physics computer stuff and can get very mathy . Geo and biogeochemistry include , obviously , a lot of chemistry , which gets mathy . So , fear not You shall find yourself crunching plenty of numbers eventually . As far as in the real world , it ' s going to depend on the type of work you end up doing . I ' m a project manager , the most difficult math I get involved with at this point is financial algebra stuff . I haven ' t done an integral in years , I ' m not even sure I ' d know how to anymore ! But I can recognize the math I see in equations and follow along , and that ' s pretty important to be able to do , I think .
