Why do I need Maths, Physics and Chemistry?
Geology is a science that builds on the fundamental natural sciences. As such, you will be using basic skills in these subjects. For example, you will be determining chemical reactions between minerals in metamorphic rocks, you will be performing and analyzing seismic experiments in the ground, looking at the propagation of waves into the bedrock, and you will be tracking the flow of water and magmas underground. All these require a basic knowledge of Maths, Chemistry and Physics.
