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.
Question 1
Which data helps forecast a landslide?
- Calm wind
- Heavy rainfall on steep, soaked slopes
- Sunny days
- Cold nights only
Heavy rainfall on steep, soaked slopes
Hint: Wet slopes slide.
Question 2
Why are mineral resources found only in some places?
- They fall from the sky
- They grow like plants
- Past geologic processes concentrated them there
- People put them there
Past geologic processes concentrated them there
Hint: Geology made them.
Question 3
Oil and natural gas formed from…
- sand only
- volcanic glass
- melted glaciers
- remains of ancient marine organisms
remains of ancient marine organisms
Hint: Buried for millions of years.
Question 4
Volcano scientists watch for warning signs such as…
- small earthquakes and ground swelling
- rainbows
- cooler weather
- more birds singing
small earthquakes and ground swelling
Hint: Magma moving.
Question 5
Why can't scientists predict the exact date of an earthquake yet?
- They have no tools
- Earthquakes are rare
- Earthquakes don't follow physics
- Faults release stress unpredictably
Faults release stress unpredictably
Hint: Probabilities, not dates.
Question 6
Copper is mined in only certain places because…
- copper grows everywhere
- ore deposits form under special geologic conditions
- only cities have copper
- it falls in rain
ore deposits form under special geologic conditions
Hint: Uneven distribution.
