Ring of Fire
Where is the Ring of Fire located
Which type of volcano is characterized by steep sides and explosive eruptions?
Composite volcano or stratovolcano
Name one type of earthquake fault.
Strike-slip, normal or reverse
What tectonic plate boundary has two plate coming together straight on?
Convergent boundary
Which layer of the Earth is composed of solid iron?
Inner core
Importance of knowing where Ring of Fire is located
Able to better predict where earthquakes will occur, tsunamis, and volcanic eruptions. Understand how tectonic plates behave.
Type of lava which is more viscous and tends to lead to explosive eruptions
rhyolitic lava and andesitic lava
This volcano has a broad, slightly domed shape and is built from many layers of runny lava
shield volcano
Outer most layer of the Earth
the crust
A layer of the Earth which is in a semi-solid state and may flow over long periods
mantle
Person who first discussed Pangea and plate tectonics along with continental drift
Wegener
Primary cause of volcanic eruptions
cement of tectonic plates
Process by which volcanic ash, dust, and gases are ejected into the atmosphere during an eruption
pryoclastic flow
Name the tectonic plate boundary which creates ravines, or new sea floor.
Divergent boundary
Thickest layer of the Earth
The mantle
Hawaiian lava with rope like structure
pahoehoe
Type of plate boundary typically associated with volcanic activity
convergent boundary or subduction
Maingas found in volcanic eruptions
sulfur dioxide
Subduction
when two tectonic plates of different densities come together, the denser one (oceanic) goes underneath the less dense one (continental).
The densest solid layer of the Earth
inner core
Volcano which is no longer active for all eternity
extinct volcano
Behavior that proceeds, or goes before, a volcanic eruption
earthquake swarm, ash, lava flow, increase pressure
Subduction zone off the west coast of Washington state
Cascadia subduction zone
Discovery sea floor spreading
Hess
Liquid dense layer of the Earth, made of iron
outer core
