Chemists analyze and manipulate materials on the molecular level, from testing substances for purity to finding new uses for existing substances to synthesizing entirely new molecules. While a few entry-level positions require only a high school diploma with some laboratory experience, almost all jobs require a bachelor’s degree in chemistry, and many require a master’s or Ph.D.
Environmental scientist have a breadth of responsibilities mainly focused on identifying, decreasing or eliminating sources of pollutants or hazards that affect the environment or the health of the population. Environmental scientists should hold at least a bachelor ‘s degree in environmental science or environmental studies.
A geohydrologist studies different geological formations to assess water resources and exploitation possibilities as they pertain to underground and surface waters as well as infiltration rates of rain and snow melt runoff. The typical educational requirement for a geohydrologist is a bachelor’s degree for most entry-level positions; however, many who pursue careers as geoscientists obtain a master’s degree in a natural science.
Hydrology engineering focuses on water flows, runoff and erosion, sedimentation, watersheds, reservoirs, floods and droughts. Hydrology engineers need a bachelor’s or master’s degree in engineering.
Physicists are highly trained scientists who experiment with physical data to reach conclusions. Employment as a physicist requires at least a Master of Science degree and sometimes a Ph.D.
Oceanographers combine the fields of geology, geophysics, biology and chemistry to study oceans and coastal waters in order to better understand their effects. A master’s degree is required for most positions.
Though the responsibilities of geoscientists vary, they are typically curious about the world and work to protect, improve and understand it. Geoscientists must have a college education in order to find work. A bachelor’s degree is adequate for entry-level positions, but a master’s degree will open more doors and is necessary in order to advance.
