100
These formed the Hawaiian Islands.
What are hot spots?
100
What is the inner core?
This is the hottest layer
100
An instrument used to measure earthquakes
What is a seismograph?
100
This occurs when two plates move away from each other.
What is a divergent boundary?
100
This is the name for the supercontinent.
What is Pangaea?
200
The type of boundary that creates a volcano when an oceanic plate moves under another plate.
What is a convergent boundary?
200
This is the thinnest layer of earth.
What is the crust?
200
The point below the surface where the earthquake occurs.
What is the focus?
200
This occurs when two plates move against each other.
What is a transform boundary?
200
This theory stated that Pangaea split and the pieces drifted into their present day location and will continue to move.
What is Continental Drift Theory?
300
The type of boundary that creates a volcano when two plates move away from each other.
What is a convergent boundary?
300
This layer is made of a solid that flows like a liquid.
What is the mantle?
300
Earthquakes are measured for magnitude and damage on these two scales.
What are the Richter and Mercalli scales?
300
This occurs when two continental plates collide.
This occurs when two continental plates collide.
300
Name one item of evidence supporting the idea of continental drift.
What is the earth looking like a puzzle, rock evidence, or fossil evidence?
400
These are created as a plate continually moves over a hot spot.
What are volcanic chains?
400
This layer is liquid iron and nickel.
What is the outer core?
400
The point on the surface above the focus.
What is the epicenter?
400
What is a collisional boundary?
This occurs when an oceanic plate moves under another plate.
400
This German scientist authored a book on the Continental Drift Theory.
Who is Alfred Wegner?
500
This is the god of fire
Who is Hephaistos or Vulcan?
500
This is the cause of the inner core being solid iron and nickel.
What is pressure?
500
Earthquakes occur at this type of boundary.
What is a transform boundary?
500
When molten rock rises and falls beneath the earth’s crust it causes movement of these.
What are plates?
500
These are the names for the two continents that Pangaea split into.
What are Laurasia and Gondwanaland?
