Lava Talk
100
Heating and cooling in the mantle that cause tectonic plates to move.
What is convection currents?
100
Number of plate boundary types.
What is three?
100
Giant gap between plates on LAND.
What is a rift valley?
100
Known for quick eruptions with little to no lava.
What is a cinder cone volcano?
100
One is melted rock above ground, the other is melted rock below the ground.
What is the difference between lava and magma?
200
Pieces of the lithosphere.
What is tectonic plates?
200
The type of boundary is dependent on these two things.
What is direction of plate movement and plate type?
200
Formed by oceanic-oceanic plate convergence.
What is a volcanic island arc?
200
Tectonic plate subduction or weakness in the crust/hot spot.
What are volcano formation methods?
200
This type of lava is very thick and very active.
What is high silica/high water vapor lava?
300
Place where new crust is created.
What is a mid-ocean ridge?
300
Two plates moving away from each other.
What is a divergent boundary?
300
Formed when a volcano collapses in on itself after erupting, where the inside is now hollow (no magma).
What is a caldera?
300
Convection currents force magma up into the volcano's main vent until it can no longer handle the heat/pressure/density changes, and erupts.
What is how does a volcano work?
300
Ash, tephra, lava, and pyroclastic material.
What is created from a volcanic eruption?
400
Property that fuels convection currents.
What is density?
400
These two boundaries destroy crust.
What is oceanic-oceanic convergence and oceanic-continental convergence?
400
Creates a volcanic MOUNTAIN range.
What is an oceanic-continental convergent boundary?
400
Volcano formed by high silica/high water vapor lava.
What is a stratovolcano?
400
This type of lava has the LOWEST viscosity.
What is low silica/low water vapor lava?
500
Source of heat for convection currents.
What is the outer core?
500
These two boundaries feed convection currents.
What is oceanic-oceanic convergence and oceanic-continental convergence?
500
Responsible for earthquakes and fault creation.
What is a transform boundary?
500
Lava type, eruption type, and appearance.
What are the differences between the types of volcanoes?
500
Land creation, destruction, and volcanic soil.
What is created by a volcano?
