  3. What do Geologists study? • rocks, • minerals, • fossils, • landforms • and tectonic plates.

  4. Geologists… • Use hammers, chisels, shovels, screens and microscopes • Record their findings in notebooks. • Spend a lot of time outdoors collecting samples and observing the earth. This activity is called field work.

  5. Geologists study… • the processes that form terrian, and the processes that destroy terrian. • The processes that destroy the terrain may cause Geological concerns or Geohazards.

  6. Geological Hazards A geologic hazard or "geohazard" is a geologic condition, either manmade or natural, that poses a potential danger to life and property.

  7. What are some Geohazards? • karst (caves and sinkholes), • mine subsidence • earthquakes • landslides • shore/coastal erosion • Indoor Radon • investigated by the Division of Geological Survey. • Wildfire-related debris flows

  8. Geohazards in Pa include… Earthquakes Sinkholes Landslides Elevated levels of Co2 Floods Methane Gas Exposure Radon Subsidence caused by underground mining
