Name that Plate Boundary
Two tectonic plates pushing against each other
Convergent plate boundary
This is formed when an oceanic plate subducts underneath another plate, destroying old ocean floor and creating a deep underwater hole
Ocean Trench
This layer of the earth is the thinnest
crust
This geologic feature happens when two continental plates diverge
Rift valley
Two tectonic plates moving away from each other
Divergent plate boundary
This is formed when two oceanic plates diverge and create a chain of underwater volcanoes
Mid Ocean Ridge
This layer of the earth is liquid
Fill in the blanks:
________ plate boundaries move toward each other, _________ plate boundaries move away from each other
Convergent, Divergent
Two tectonic plates grinding past each other
Transform plate boundary
Which kind of plate boundary forms new oceanic crust?
divergent oceanic plate boundary
Earth's inner core is solid due to
Pressure
Plates that grind past each other are called
transform plate boundaries
Sea floor spreading happens along this type of boundary
Divergent plate boundary
When an oceanic plate collides with a continental plate, which plate subducts, or gets forced underneath?
The oceanic plate is forced under the continental plate
This layer of the earth is the most dense
Inner core
Circular currents in the mantle that cause changes to the earth's surface are called
convection currents
Earthquakes happen at this type of plate boundary
All plate boundaries
The volcanoes in Hawaii are formed as tectonic plates move over these
Hotspots
Convection currents that cause changes in the earth surface are located in this layer
Mantle
Name the layers of the earth in order, starting from the outside
Crust, mantle, outer core, inner core
