A1Back
Layer of earth made of hot, solid metals
Answer
What is the inner core?
A2Back
The Earth’s thickest layer
Answer
What is the mantle?
A3Back
The layer made of liquid metals that surrounds the inner core.
Answer
What is the outer core?
A4Back
Earth’s crust and very top of the mantle together
Answer
What is the lithosphere?
A5Back
A layer of hotter, softer rock in the upper mantle
Answer
What is the asthenosphere?
B1Back
Hypothesis that Earth’s continents were once joined in a single landmass
and gradually moved
Answer
What is continental drift?
B2Back
This is what they called all of the continents joined as one huge
supercontinent
Answer
What is Pangaea?
B3Back
Huge underwater mountain ranges
Answer
What are mid-ocean ridges?
B4Back
A circulation pattern in which material is heated and rises in one area, then
cools and sinks in another
Answer
What is convection current?
B5Back
It states that the Earth’s lithosphere is made up of huge plates that move
over the surface of the Earth
Answer
What is the theory of plate tectonics?
C1Back
A deep valley formed as tectonic plates move apart
Answer
What is a rift valley?
C2Back
An area where a column of hot material rises from deep within a
planet’s mantle
Answer
What is a hot spot?
C3Back
This occurs where plates push together
Answer
What is a convergent boundary?
C4Back
This is where two plates move apart, most are found in the ocean
Answer
What is a divergent boundary?
C5Back
This occurs where plates scrape past each other
Answer
What is a transform boundary?
D1Back
In the ocean, divergent boundaries are called this
Answer
What is a spreading center?
D2Back
The process by which an oceanic tectonic plate sinks under another
plate
Answer
What is subduction?

D4Back
A boundary along which two plates carrying continental crust push
together
Answer
What is continental-continental collision?
D5Back
A boundary along which a plate carrying oceanic crust sinks beneath
a plate with continental crust
Answer
What is oceanic-continental subduction?

E2Back
A thin layer of cool rock
Answer
What is the crust?
E3Back
Large, moving pieces into which Earth’s lithosphere is broken
Answer
What are tectonic plates?
E4Back
A switch in the direction of Earth’s magnetic field
Answer
What is magnetic reversal?
E5Back
A boundary along which a plate carrying oceanic crust sinks beneath
another plate with oceanic crust
Answer
What is oceanic-oceanic subduction?
