I am a college student studying geology. Geology has many branches, including mineral exploration, engineering and geological disasters. For the latter two, the requirements for mathematics may be higher, and physical mechanics must be solid. For mineral exploration, because of its strong theory, the requirements for mathematics are relatively low. Even if you choose the first one in the postgraduate entrance examination, you may have a direction of not taking math exams. The relationship between geography and geology should actually be regarded as two concepts. Geography studies some of the surface, such as topography, and may also involve biology, while geology mainly studies underground phenomena, such as the formation of strata, some faults and structures, which provide the basis for mineral exploration and civil buildings, so it should be treated differently. Geology is a hard job. You may often work in the field, but it is also very interesting. If you are a girl, I suggest you apply for another major. If you are a boy, and you are not afraid of hardship, this should be regarded as a good major, because our country is still short of talents in this field. I hope the above answers are helpful to you. I wish the exam success!
