200
What type of magma has these properties: -Sticky -High viscosity -Lighter in color
Felsic
200
What are the three volcanic zones?
Rift, subduction, and hot spot
200

Shield
300
What are the characteristics of the continental crust?
The continental crust is thicker and less dense than the oceanic crust.
300
What happens at a transform boundary?
A tectonic plate slides past another tectonic plate
300
Out of this list, name the liquid with the highest and the one with the lowest viscosity: -Maple Syrup -Water -Peanut Butter -Molasses

300
What are two properties of a composite cone?
-Tall -Explosive eruptions -Felsic magma -Steep slope
300
What type of zone is the whole Hawaiian island chain?
Hot spot
400
What are the differences between the oceanic crust and the continental crust?
The oceanic crust is thinner and more dense, and the continental crust is thicker and less dense.
400
Why is the Juan de Fuca plate boundary considered a triple junction?
The boundary contains all three boundary types (divergent, convergent, and transform)
400
What are three properties of Mafic magma?
-Low viscosity -Darker in color -Low levels of silica -Contains heavier elements
400
Name three differences between a composite cone and a shield cone.
-Composite cone is tall/narrow at the top while a shield cone is wide and shorter -Composite cone has explosive eruptions while shield cones have gentle eruptions -Composite cone has steep slope while shield cone has gentle/broad slope -Composite cones have felsic magma while shield cones have mafic magma
400
What is the asthenosphere?
The layer below the lithosphere which is the upper most layer of the mantle
500
How are tectonic plates like puzzle pieces?
The tectonic plates fit together as many pieces on the lithosphere of the earth.
500
What kind of boundary(s) is the Mid-Atlantic Ridge, and why?
The Mid-Atlantic Ridge is a divergent boundary since the two tectonic plates are separating. The Mid-Atlantic Ridge is also a transform boundary since the two tectonic plates are sliding past each other.
500
What kinds of volcanoes and eruptions do both felsic and mafic magma form?
Felsic: -Composite volcanoes -Explosive eruptions Mafic: -Shield volcanoes -Gentle eruptions
500
Name two world examples of composite cones.
-Hekla -Reventador -Mt. Vesuvius -etc.
