• something to put food on

• movement of the land

convergent plate boundary

• when one plate moves against another

• where one plate moves away from another

• where one plate touches another

• when a plate moves on its own

earth's layers in order from outside to inside

• asthenosphere, outer core, inner core, lower mantle

• inner core, asthenosphere, lower mantle, outer core

• asthenosphere, lower mantle, outer core, inner core

• outer core, lower mantle, asthenosphere, inner core

volcano chain

• a randomly occurring chain of volcanos

• a cluster of volcanoes

• where subduction zone plates create a chain of volcanoes on the surface

• where convergent plate boundaries create a chain of volcanoes on the surface

stratavolcano

• composed of alternating layers of volcanic ash and lava flows

• over time different layers of rock form over the existing ones, creating and supermassive volcano

• composed of alternating layers of different aged rock (precambrian and mesozoic)

• magma and debris fall back onto the volcano when it erupts.

cascade subduction zone

• oceanic plate sucked beneath North America plate

• magma buoyancy brings the magma to the surface forming volcano chain

• the oceanic plate drifts away from North America causing a hole where everything gets sucked into

• this hole forms the deep ocean trench

subduction

• the denser plate descends beneath another plate

• the lighter plate descends beneath another plate

• the plate gets really close to another plate

• a massive hole where the plates drift away

volcanoes may erupt:

• grey:molten rocks as lava flows

• grey: particles of volcanic ash and larger blocks of rock

• red: particles of volcanic ash and larger blocks of rock

• red: molten rocks as lava flows
