Slide #2
You must be in presentation mode
Click and play the “Ring of Fire Map” below
Locate volcanoes and draw dots on your map. They most often occur on convergent plate boundaries
Locate earthquakes and draw “X’s” on your map. They occur on most plate boundaries.
Most tectonic activity is at plate boundaries!
The most active region is called the “RING OF FIRE”
Where are volcanoes that are NOT located on plate boundaries?

3. Slide #3 Hawaiian Islands Map
Record the ages of the volcanic Hawaiian Islands
Hawaii is the only island with active volcanoes.
No other Hawaiian islands have active volcanoes
Hawaii is the only island over a HOT SPOT were magma from the mantle rises through the crust. There’s no plate boundary located here!

4. Slide #4 Draw a diagram that shows hot spot island formation…
INACTIVE VOLCANO
Oceanic Plate
Hot Spot Magma
Magma forms_________but the ocean plate _____ and carries the island with it!
a volcano
moves
ACTIVE VOLCANO
In a few million years, an ___________ is formed!
Island chain

6. Slide #5 Locate OCEANIC HOT SPOTS on the ESRT tectonic plate map
Hawaii
Iceland
Canary Islands
Tasman
Bouvet
But hot spots can be on the continents too…
Yellowstone
Any volcanoes in Yellowstone?
OF COURSE!
And there are LOTS of geysers and hot springs!
Someday… one of the largest volcanoes in the world will…

7. Slide #6 1. How do volcanoes form at convergent plate boundaries?
2. How do volcanoes form at hot spots?
3. ESRT p5: In what compass direction is the Pacific plate moving?
4. Which Hawaiian island is the youngest? Oldest?
5. How do the ages of these islands show the direction of movement of the Pacific plate?
6. Where is the newest Hawaiian Island forming now? Why is it not visible?
