Plate Movements
This occurs when two plate boundaries move away from each other.
What is a divergent boundary?
What is Pangea.
This is the hottest layer.
What is the inner core?
An instrument used to measure earthquakes.
This occurs when two plates move against each other.
What is a transform boundary?
This theory stated that Pangea split and the pieces drifted into their present day location and will continue to move.
What is Continental Drift Theory?
This is the thinnest layer of Earth.
What is the crust?
The point below the surface where the earthquake occurs.
What is the focus.
The type of boundary that creates a volcano when an oceanic plate moves under another plate (subduction).
What is a convergent boundary?
This occurs when two continental plates collide.
What is a collisional boundary?
Name one item of evidence supporting the idea of continental drift.
What is the earth looking like a puzzle, rock evidence, fossil evidence, or glacial evidence?
This layer is made of a solid that flows like a liquid.
What is the mantle?
Earthquakes are measured for magnitude and damage on these two scales.
What are the Richter and Mercalli scales?
The type of boundary that creates a volcano when two plates move away from each other.
What is a divergent boundary?
This occurs when an oceanic plate moves under another plate.
What is a convergent boundary?
Who is Alfred Wegener?
This layer is liquid iron and nickel.
What is the outer core?
The point on the surface above the focus.
What is the epicenter?
These are created as a plate continually moves over a hot spot.
What are volcano chains?
When molten rock rises and falls beneath the earth's crust it causes movement of these.
What are the plates?
These are the names for the two continents that Pangea split into.
What are Lauasia and Gondwanaland?
This is the cause of the inner core being solid iron and nickel.
What is pressure?
Earthquakes occur at this type of boundary.
What is a transform boundary?
This is the god of fire.
