Oregon Resources & Hazards

Where resources are, and forecasting natural hazards.

What your child practices

Practices why Earth's mineral, energy and groundwater resources are unevenly spread, and how scientists use data to forecast hazards and reduce their effects, with Oregon examples like the Cascadia Subduction Zone, tsunami maps for the coast, Cascade volcanoes and geothermal heat near Klamath Falls.

Oregon State Standards learning standard: 7.ESS3.1; 7.ESS3.2 · why resources are unevenly distributed, and using hazard data to forecast events and plan safety

Sample questions

A taste of this unit. In the app, questions change every time and get easier or harder to match your child.

    Which data helps forecast a landslide?

    • Calm wind
    • Heavy rainfall on steep, soaked slopes

    • small earthquakes and ground swelling
    • rainbows
    • cooler weather
    • more birds singing
  5. Question 5
