Earth's Layers
This is the innermost layer of our earth and is a solid
What is the inner core?
This primary volcano has violent eruptions and can be very steep due to the many layers that have accumulated
What is a composite volcano?
This is the result of an active transform boundary
This type of lava has the lowest viscosity
What is mafic lava?
This layer is just outside the inner core and is liquid
What is the outer core?
This type of plate boundary occurs when plates collide
What is a convergent plate boundary?
This secondary volcano is formed from debris falling back down after an eruption
What is a cinder cone?
This is the result of a divergent plate boundary in the ocean
What are mid-ocean ridges?
This type of rock is formed by mid-ocean ridges
What is basalt?
This causes the Earth's inner core to stay at a solid despite the temperature
What is Pressure?
This type of plate boundary occurs when plates slide past each other
What is a transform plate boundary?
This primary volcano is formed from mafic lava adding thin layers over a large surface area (often in oceans)
What is a shield volcano?
This determines which plate will dive underneath another in a convergent interaction
What is plate density?
This type of secondary volcano has felsic lava and may be formed by spilling slowly out of a vent
What are lava domes?
This is the name for the crust and upper mantle
What is the lithosphere?
This layer of earth is what makes of plates (not crust)
What is the lithosphere?
This type of lava causes the most violent eruptions
What is felsic lava?
This term is used to describe one plate diving beneath another
What is subduction?
This term describes when the top of a volcano collapses inward (Crater Lake)
What is a caldera?
What are convection currents?
This is the man that first came up with plate tectonics theory
Who is Alfred Wagner?
This term describes volcanoes that form in the center of plates, away from plate boundaries
What are hot spots?
These two types of crust often form mountain ranges when in a convergent boundary
What is a continental - continental interaction?
This term is used to describe how thick a substance is
What is viscosity?
