When you touch a hot plate, the transfer from the heat to your hand is an example of this.
What is conduction?

Wegner named the supercontinent this, which means "all lands"
What is Pangea?
100
The longest chain of mountains in the world.
What is the mid-ocean ridge?
100
The geological theory that states that the pieces of the Earth's lithosphere are in constant, slow motion.
What is plate tectonics?
200
The study of planet Earth
What is geology?
200
Feeling the heat from the sun is this kind of heat transfer.
What is radiation?
200
Wegner's hypothesis of continental drift states that the continents were once joined together in a single landmass and have since done this.
What is drift apart?
200
Scientists in the mid-1900s used sonar to do this.
What is map the mid-ocean ridge?
200
This landform is made when two continental crust collide.
What are mountains?
300
To observe Earth's interior, geologist record and study this
What is seismic waves?
300
This kind of heat transfer happens in the asthenosphere.
What is convection currents?
300
The mesosaurus, lystrosaurus, and glossopteris, are these traces of ancient organisms preserved in rock.
What are fossils?
300
The three types of evidence of sea-floor spreading.
What is molten material, magnetic stripes, and drilling samples.
300
This type of boundary causes earthquakes, when two plates slip past each other, moving in opposite directions.
What is transform boundary?
400
Starting from the surface, these are the layers of the earth.
What is crust, mantle, outer core, inner core?
400
If we remove the heat source from a fluid the fluid will do this.
What is eventually stop?
400
The three types of evidence of continental drift.
What is fossils, landforms, and climate?
400
When the sea floor spreads, the new rock pushes through the crack pushing these out.
What is the older rock?
400
When two continental plates are diverging, this landform is made.
What is a rift valley?
500
The mantle is made made up of these two layers.
What is lithosphere and asthenosphere?
500
When the convection currents from the mantle heat material, the material becomes this.
What is less dense and rise.
500
The two types of evidence that linked Africa and South America ever being joined.
What mountain ranges, glossopteris, lystrosaurus, and mesosaurus?
500
Dense oceanic crust sinking back into the mantle is this process, which creates trenches.
What is subduction?
500
This causes the plates to move.
