Rocks in Hawaii form from (magma/lava)
Lava
this event happens at every plate boundary.
earthquake
true or false: The plates and continents do not move
false
The term to describe when a volcano is no longer
Extinct
The equation for density
D=m/V
The duration a rock cools controls this.
Texture or grain size.
A ridge only forms at this type of plate boundary
divergent
this event/scenario is why plates move
convection currents
What feature creates an active volcano and appears to move due to the slighting of tectonic plates
Hotspot
In a layering of multiple materials the least dense substance is located here
At the top
The term for lava that tends to form DARK rocks
mafic
Provide one of the features that can form at a convergent boundary
Mountains, trenches, volcanoes
what causes a convection current
change in temperature/density within the mantle
This type of volcano has a very shallow slope and has frequent interruptions of lava (Hawaii)
Shield volcano
Between oceanic and continental crust which has a higher density
oceanic
This type of rock forms outside earth's crust
Extrusive

transform
this type of seismic wave arrives last during an earthquake
Secondary S-Wave
This type of volcano has a very steep slope and has very long periods of time between eruptions where it ejects rock and ash. (Mount Saint Helens)
Cinder cone volcano
in general when you heat up something its density does this
decreases
This word describes one rocks develop a porous/hole-y texture due to gas bubbles when cooling
Vesicular
what is formed at an oceanic ridge due to the plates diverging?
new rock/crust
this type of seismic wave can travel through liquid
Primary P-Wave
This term describes fragments of rock, ash, and gas ejected during explosive volcanic eruptions
Pyroclast
what is the density for a rock with a mass of 500 g and a volume of 150 cm3
3.33 g/cm3
