Environmental geosciences equip earth-science students with environmental or interdisciplinary interests the foundation to enter careers or advanced studies in geoscience fields connected to the environment, particularly in water resources, water pollution and cleanup, oceanography, and climate change.
Numerous earth scientists work across multiple disciplines.
Geochemists examine the chemical composition of everything from surface and groundwater to molten rock and crustal formations; apply geochemical methods to locate new mineral and energy deposits; and tackle environmental issues tied to resource extraction.
Biogeochemists study how chemical elements circulate through Earth's systems, from vital nutrients like carbon, nitrogen, and phosphorus to hazardous metals such as mercury and uranium.
Geobiologists focus on fossil paleontology, biogeography, and functional evolution; the paleoecology of ancient organisms, their development, and life's progression; and creating a chronological sequence for past geological and climatic occurrences.
Geophysicists analyze Earth's gravitational, magnetic, and electrical fields; interpret seismic waves from natural and artificial sources; and map underground water and hydrocarbon deposits along with potential leaks.
