Guided Notes: 3 Types of Volcanoes
Shield
Forms on hot spots
Broad base, small incline
Enormous height (including base below sea level)
Thin lava makes it the least explosive
EX: Mauna Loa in Hawaii
Cinder
Cone-shaped mound of ash
Smallest
Forms on sides of other volcanoes
Forms in groupsEX: Capulin in New Mexico, Mount Paricutin in MexicoComposite (Stratovolcano)Creates lahars (mudflows/landslides)Forms from layers of lava (from many eruptions)May remain dormant for long periods between eruptionsThick lava makes it the most explosive EX: Mount St. Helen’s in Washington, Mount Vesuvius in ItalySlide6
Volcano Articles
Working individually, read the following articles and answer the accompanying questionsSlide7
Raging Planet: Volcanoes
While watching the Raging Planet: Volcanoes, answer the questions on your worksheetSlide8
Warm Up
How does a volcano’s amount of activity relate to it’s explosiveness?
How does a volcano’s magma temperature relate to it’s destructive potential? Slide9

What kind of destruction can you see?
What kind of destruction may have occurred that you cannot see?Slide11
Earthquake Survival Activity
Ms. McGowan will split you into groups of 4
In your groups, take turns reading the Earthquake Survival Script
Then, work together to determine what actions you would take post-earthquakeSlide12
Notes: Seismic Waves
Body Waves—travel through Earth’s interior
P waves
Particles move parallel to wave
Travels through anything
Fastest speed
S waves
Particles move
p
erpendicular to wave
Only travels through solids
Medium speedSurface Waves—travel through Earth’s surfaceSlowest speedSlide13
Seismic Waves Slinky Demonstration
Follow along on your Seismic Waves Demonstration Worksheet as Ms. McGowan demonstrates seismic waves with her slinkySlide14
