Volcanoes Magma vs. Lava Liquid rock that forms under Earths
surface!
When magmaerupts on Earthssurface! Volcanism Any movement of magma
onto Earths surface!
Volcano The vents in Earths surface which magma and gases are
released. Where do Volcanoes form?
Plate Boundaries Convergent Boundaries (Subduction Zones) Converge
= Collide/Move Together Divergent Boundaries (Mid-Ocean Ridges)
Diverge = Move Away Hot Spots Major zone of active volcanoes that
circles the pacific ocean!
Major Volcanic Zones Active volcanoes occur near both convergent
and divergent plate boundaries! Volcanic Zones Most volcanoes are
located near both convergent and divergent plate boundaries.
Pacific Ring of Fire Major zone of active volcanoes that circles
the pacific ocean! Convergent Boundary Boundaries that form when
two plates collide.
Three Types of Plate Collisions Oceanic and Continental Oceanic and
Oceanic Continental and Continental Subduction Zone Zone where one
tectonic plate moves under another. Lava flows to surface forming a
volcano. Divergent Boundary When two plates move away from each
other
Divergent Boundary When two plates move away from each other!
Mid-Ocean Ridges form in this area and magma rises to the surface
forming a volcano! Hot Spot Volcanically active site away from a
plate boundaries where large balls of magma (mantle plumes) rise
and reach the surface!
