Plate Boundaries
100
The rock that makes up the continental crust.
What is granite?
100
Heat transfer within a fluid.
What is convection?
100
The name of the past supercontinent that means "all lands."
What is Pangaea?
100
The technology used in the mid-1900's to map the ocean floor.
What is sonar?
100
The type of plate boundary where two plate collide.
What is a convergent boundary?
200
This increases as you move from the crust to the inner core.
What is pressure?
200
A measure of how much mass there is in a volume of a substance.
What is density?
200
The remains of an ancient organism preserved in rock.
What is a fossil?
200
The place where subduction occurs.
What is a deep-ocean trench?
200
The type of plate boundary located along the mid-ocean ridge.
What is a divergent boundary?
300
This is the soft, flowing middle layer of Earth's mantle.
What is the asthenosphere?
300
Convection currents in this layer create Earth's magnetic field.
What is the outer core?
300
The hypothesis that the continents slowly move across Earth's surface.
What is continental drift?
300
The place where oceanic crust is the youngest.
What is along the mid-ocean ridge?
300
These are responsible for the movement of Earth's plates.
What are convection currents?
400
This layer is broken into pieces called plates.
What is the lithosphere?
400
Sunlight and a campfire are examples of this.
What is radiation?
400
The shapes of continents, epicenter locations, landforms, glacial deposits and this are all evidence supporting the continental drift hypothesis.
What are fossil locations?
400
A process that continually adds new material to the ocean floor.
What is sea-floor spreading?
400
A break in Earth's crust where masses of rock slip past each other.
What is a fault?
500
A scientist who studies the forces that make and shape the Earth.
What is a geologist?
500
Convection currents will eventually stop if this is removed.
What is the heat source?
500
The geologist that proposed the hypothesis of continental drift.
Who is Alfred Wegener?
500
The scientist that helped discover and explain the process of sea-floor spreading.
Who is Harry Hess?
500
The type of plate boundary where two plates slip past each other often causing earthquakes.
What is a transform boundary?
