A3Back
The layer made of liquid metals that surrounds the inner core.
Answer

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?
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?
C2Back
An area where a column of hot material rises from deep within a
planet’s mantle
Answer
What is a hot spot?
C4Back
This is where two plates move apart, most are found in the ocean
Answer
What is a divergent boundary?
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?
E3Back
Large, moving pieces into which Earth’s lithosphere is broken
Answer
What are tectonic plates?
