2. Answer the questions

5. LAVA vs. MAGMA LAVA = above/on Earth’s surface
MAGMA = below Earth’s surface

6. Volcanic Eruptions Can be DESTRUCTIVE
when an eruption is explosive it changes the landscape of and around the volcano
Can be CONSTRUCTIVE
adds new rock to existing land
forms new islands

9. WHY DO WE CARE?
Scientists study and volcanic activity in order to support the theory of plate tectonics.
The evidence proves that there is a distinct relationship between VOLCANIC ACTIVITY and PLATE TECTONICS (plate movement)

10. Where do volcanos occur
Where do volcanos occur? When plates interact at boundaries, there is much more volcanic activity at these places.
Convergent Boundary
Subduction Zone = crust melts and magma rises through
Forms: Volcanoes and Volcanic Island Arcs

12. Where do volcanos occur
Where do volcanos occur? When plates interact at boundaries, there is much more volcanic activity at these places.
Divergent Boundary
Magma pushes between plates (rift zones) as plates pull apart
Forms: NEW CRUST at Mid-Ocean Ridges and Rift Valleys

13. Magma = less dense than surrounding rock
Rises to surface, forms new crust

15. Where do volcanos occur
Where do volcanos occur? When plates interact at boundaries, there is much more volcanic activity at these places.
Hot Spots
An area in the mantle where heat rises from deep in the Earth
Higher heat and low pressure in the Lithosphere melts rock into Magma
Magma rises through cracks and erupts to form volcanoes

16. Hot Spots are STATIONARY (stay in one place)
Hot Spots continued…
Hot Spots are STATIONARY (stay in one place)
Plate moves over the hot spot and a volcano forms
As plate moves, the volcano breaks away and moves with the plate
This makes room for a new volcano over the hot spot
Forms: Volcano chains  HAWAIIN ISLANDS

17. PACIFIC RING OF FIRE

18. PACIFIC RING OF FIRE Surrounds the majority of the Pacific Ocean Basin
HIGH volcanic activity because of Converging plate boundaries that border the Pacific Ocean Basin
Ring of Fire is great PROOF of plate motion for scientists

19. What do underwater volcanoes look like when they erupt? (video)
