Any trace of an ancient organism that has been preserved in rock.
What is a fossil?
100
The top layer or earth's surface
What is the crust?
100
When energy moves from one place to another.
What is heat transfer?
100
The geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion.
What is plate tectonics?
100
A collision between two pieces of continental crust at a colliding boundary.
What produces a mountain range?
200
The name of the super-continent that existed millions of years ago.
What is Pangaea?
200
Pressure does this as you move from Earth’s surface toward the center of Earth.
What is increases?
200
The transfer of energy through empty space.
What is radiation?
200
They are found in all of Earth’s oceans.
What are mid-ocean ridges?
200
A place where two plates slip past each other, moving in opposite directions.
What is a sliding or transform boundary?
300
A technology scientists used in the mid-1900s to map the mid-ocean ridge.
What is sonar?
300
Earth's layer below the lithosphere.
What is aesthenosphere?
300
The transfer of heat by the movement of heated fluid.
What is convection?
300
A place where two plates slip past each other, moving in opposite directions.
What is a sliding or transform boundary?
300
Fifteen of these make up the earth's surface.
What are land masses?
400
It forms at a spreading plate or divergent boundary.
What is a rift valley?
400
Adenine, thymine, cytosine and guanine.
What are amino acids or bases?
400
Mantle material rises in convection currents because heated materials become this.
What is less dense?
400
Old oceanic crust is more dense than new oceanic crust for this reason.
What are cool?
400
Geologists obtain indirect evidence about Earth’s interior by recording and studying these.
What are seismic waves?
500
He provided evidence from landforms, fossils, and climate in support of his theory of the continental drift.
Who was Alfred Wegener?
500
An area where oceanic crust is younger than oceanic crust on the edges of the ocean.
What is a mid-ocean ridge?
500
Mantle material fall in convection currents because cooler materials become this.
What is more dense?
500
Most geologists rejected Alfred Wegener’s idea of continental drift because Wegener could not identify a this that could move the continents.
