What is geoscience?
Earth science or geoscience is a blanket term used to describe the study of our home planet. It is a branch of planetary science that focusses on Earth and spans a large variety of sub-disciplines as detailed below.
Fields of study:
Atmospheric sciences: the study of Earth’s atmosphere, including aeronomy, climatology, meteorology, atmospheric physics, atmospheric chemistry, and weather forecasting.
Ecology: the study of all biota and how they interact with the planet, including biogeochemical cycles, soil formation, natural resource management, agriculture, how geographic locations affect life, and human impact on the planet and other forms of life. Ecology is not synonymous to environmental engineering.
Hydrology, oceanography, and limnology: the study of water, oceans, and inland water bodies, including hydrogeology, water quality management, oceanic currents, ecohydrology, geophysical fluid dynamics, the sea floor, freshwater on earth, and all other kinds of water bodies on earth.
Geology: the study of the lithosphere, including the development and study of rock and land, economic geology (study of metallic and non metallic resources, waste disposal, mineral water), engineering geology (application of geological data, techniques, and principles to the study of rock and soil surficial materials and ground water), environmental geology (study of the interaction between the geosphere, hydrosphere, atmosphere, biosphere, and human activities), marine geology (study of the sea floor, continental shelves, water-land boundary), geochronology, sedimentology, soil science, and stratigraphy.
Geochemistry: the study of inorganic and organic chemistry on earth, including the nature and distribution of major and trace elements, and fossil fuel.
Geodynamics, Seismology, and Volcanology: the study of continental plates, earthquakes, and volcanoes, including seismic waves, continental collision, magma, lava, orology (mountain building), oceanic trenches, and seafloor spreading.
Geophysics and Geodesy: the study of the internal structure, formation, and the shape of the earth, including gravitational, electric, and magnetic fields, 3D modeling of the geoid, geodynamo, the Van Allen radiation belts, magnostratigraphy, magnetohydrodynamics, and the structure of the earth’s interior.
Geomorphology: the study of how surface features are shaped, including study of landscapes, rivers, mountains, landforms, human impact on shaping of landscape, urban studies, and archaeology.
Glaciology: the study of glaciers and ice on earth, including the study and spread of ice sheet, the ice ages, ice flow from the mountains.
Mineralogy and Petrology: the study of minerals and mineral compositions of rock, including crystallography, gemology, lithology, and petrography.
Paleontology and Paleoecology: the study of fossils to determine evolution of life, organisms, and reconstruction of the ecology of the past, including study of life, evolution, oxygen and water on earth, fossil fuel, the sun’s effect on past life, paleoclimatology, dynamics of ecosystem change, ice ages, mass extinctions, and dinosaurs.
