Science is broken up into four branches: Physical ScienceEarth ScienceLife ScienceFormal Science Each of these branches have a few main branches, and then sub-fields within those branches. I know it sounds a little confusing, but it won’t be after I break it up for you. Let’s start with the branches of Physical Science. The main branches of Physical Science are: PhysicsChemistryAstronomy Each of these branches have sub-fields: Physics has Optics, Nuclear Physics, Mechanics, Atomic Physics, and more.Chemistry has Biochemistry, Industrial Chemistry, Physical Chemistry, Polymer Chemistry, and more.Astronomy has Astrophysics, Astrobiology, Solar Astronomy, Planetary Astronomy, and more. The main branches of Earth Science are: GeologyMeteorologyOceanography Each of these branches have sub-fields: Geology has Physical Geology, Mineralogy, Petrology, Historical Geology, and more.Meteorology has Physical Meteorology, Synoptic Meteorology, Dynamic Meteorology, and more.Oceanology has Marine Bio...
