Geology The study of the solid Earth Volcanology Paleontology Seismology Earthquakes Volcanoes Fossils
Oceanography The study of the ocean Physical Biological Geological Chemical Waves and ocean currents Natural chemicals and pollution Ocean plants and animals Ocean floor
Meteorology The study of the Earth’s atmosphere Weather Hurricanes Tornadoes
Astronomy The study of all things beyond Earth Planets Stars Asteroids
Special Branches Not limited to Environmental Science Ecology Geochemistry Geography & Cartography
Summary Earth science can be divided into three general categories: 1. Geology 2. Oceanography 3. Meteorology
Summary Careers in Earth science often require knowledge of more than one science 1. Geochemistry- geology and chemistry 2. Environmental science- life science, chemistry, physics and geology 3. Ecology- biology, geology, chemistry climatology, computer technology and math 4. Geography & Cartography- geology, life science and physics
