1 What is geoscience?

2 Geoscience a group of related disciplines focused on the Earth and its systems, history, and resources it’s more than just rocks: geoscience also involves climate, plants, asteroids, fossils, archaeology, pollen, glaciers, lakes, etc.

3 Geoscience looks at everything involving the Earth and other planets, little picture to big picture also investigates ways that geology can help or harm people

4 Little picture (grains of sand to molecules & atoms) grains of sand (sedimentology) crystals (mineralogy and crystallography) molecules in groundwater individual atoms (isotope geochemistry)

5 Big picture (Earth as a whole) plate tectonics composition and structure of the crust, mantle, and core impact cratering formation and evolution of the Earth

6 Big picture (Earth as a whole) some fields of geoscience into the big picture: geophysics seismology structural geology planetary science

7 Geologic hazards geologic events that can harm people or property, such as volcanoes earthquakes landslides and avalanches sinkholes floods

8 Geologic hazards areas of geoscience that study these hazards include: volcanology seismology geophysics engineering geology geomorphology hydrology

9 Natural resources geologic materials used by people, such as: energy (petroleum, coal, geothermal, hydroelectric) materials (metals, gemstones, sand and gravel) fresh water fertile soil

10 Natural resources areas of geoscience concerned with natural resources include: exploration geophysics mineral mining hydrology soil science

11 Earth history some geoscientists study changes in the Earth’s past, such as: past climate evolution of the atmosphere ice ages past plant and animal life mass extinctions human evolution

12 Earth history geoscience fields involved in this research: paleoclimatology dendrochronology paleontology paleoanthropology geoarchaeology chronometry

13 Summary Geoscience is a very broad field involving the study of the Earth and other planets, from atoms and molecules to planetwide events like earthquakes There are many diverse careers involved in geoscience research
