who had the theory of continental drift
Alfred wegener
What type of plate boundary moves apart from another
divergent plate boundary
Where does the liquid magma form a pool
magma chamber
A break or crack in the earths lithosphere
fault
Magma that reaches the surface of the earth
lava
The thickness of a liquid
viscosity
What type of plate boundary moves past eachother
transform boundry
where does the ash and lava exit the volcano
vent
Shaking of the ground caused by tectonic movement
earthquake
Volcano that has flowing lava and magma constantly inside of it
Active volcano
Where are most volcanoes found
ring of fire
What type of plate boundary moves against eachother
convergent boundary
Cloud that comes out of the top of the volcano
ash cloud
Force being applied to an object using a pulling force
tension
An area where magma from deep within the mantle melts through the crust
hot spot
Why does Hawaii have volcanoes even though it is in the middle of a tectonic plate.
stationary hot spot
Where is the only transformer boundary located
San Andreas fault in California.
Indent in the top of a volcano
crater
Force being applied to an object with a pushing force
compression
Why do volcanoes erupt
built up pressure
Why does MN have earthquakes
Second layer of techtonic plates under the ones on the surface
what are the three types of plate boundaries?
transform, convergent, and divergent
Solid material that shoots out of a volcano
lava bombs
