Plate Boundaries
This type of boundary involves 2 plates moving away from one another
Divergent
This volcano has gentle sloping sides, created from thick lava flows
Shield Volcano
Hardening of lava when it cools down as it reaches Earth's surface
Crystallization
This volcano was discussed in our unit challenge, and is found in Hawaii and constantly erupting
Kilauea
This is the largest layer of Earth
Mantle
This type of boundary involves 2 plates moving towards one another
Convergent
This type of volcano is a large volcanic crater in the ground, often forming lakes inside of its base after a magma chamber collapses
Caldera
This is how volcanoes are formed when they are not on a plate boundary
Hot Spot
Mount Saint Helens is located on a plate boundary with large amounts of thermal energy flow. Is this a region of change or stability?
Change
Molten material above the surface of Earth
Lava
This type of boundary involves two plates sliding past one another
Transform
This type of volcano is very tall and steep, with a crater shaped divet at the top where the fumarole is located
Cinder Cone Volcano
Theorized by Alfred Wegener, this idea led to the theories of Plate Tectonics and Pangea
Continental Drift
This region along the ring of the Pacific Ocean is where we find the most active volcanoes in the world, along many plate boundary lines
Ring of Fire
Crystallized, black, volcanic rock
Basalt
This is a transform boundary in California - the biggest transform boundary in the world!
San Andreas Fault
Very explosive, large, pointed volcanoes known for being very dangerous
Stratovolcano
The process of an oceanic plate moving under a continental plate at a convergent boundary
Subduction
This is a supercontinent discovered due to the shape of the continents and fossil evidence
Pangea
Convergent
New crust is created at this type of boundary
Divergent
A volcanic eruption that has thick, slow molten lava flows
Effusive
Movement in the mantle caused by the rising of heated fluid and sinking of cooled fluid
Convection Currents
This is the tectonic plate the Ring of Fire surrounds
Pacific Plate
Volcanoes, Earthquakes, Mountain Ranges, and Mid Ocean Ridges can all be found here
