What is geoscience? Slide 2 Geoscience a group of related
disciplines focused on the Earth and its systems, history, and
resources its more than just rocks: geoscience also involves
climate, plants, asteroids, fossils, archaeology, pollen, glaciers,
lakes, etc. Slide 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 Slide 4
Little picture (grains of sand to molecules & atoms) grains of
sand (sedimentology) crystals (mineralogy and crystallography)
molecules in groundwater individual atoms (isotope geochemistry)
Slide 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 Slide 6 Big picture (Earth as
a whole) some fields of geoscience into the big picture: geophysics
seismology structural geology planetary science Slide 7 Geologic
hazards geologic events that can harm people or property, such as
volcanoes earthquakes landslides and avalanches sinkholes floods
Slide 8 Geologic hazards areas of geoscience that study these
hazards include: volcanology seismology geophysics engineering
geology geomorphology hydrology Slide 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 Slide 10 Natural resources areas
of geoscience concerned with natural resources include: exploration
geophysics mineral mining hydrology soil science Slide 11 Earth
history some geoscientists study changes in the Earths past, such
as: past climate evolution of the atmosphere ice ages past plant
and animal life mass extinctions human evolution Slide 12 Earth
history geoscience fields involved in this research:
paleoclimatology dendrochronology paleontology paleoanthropology
geoarchaeology chronometry Slide 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
