What is Pangea?
Super Continent
100
Which is more dense- continental or oceanic?
Oceanic
100
What are the 3 types of rocks
Sedimentary, Igneous, Metamorphic
100
What is an IV
What you change in an experiment
200
Unbalanced force...
causes an objects motion to change
200
What was Alfred's hypothesis?
Once was 1 continent, which drifted apart.

Recite layers of Earth starting from the surface to the center.
Crust, Mantle, Outer core, Inner core
200
Which type of rock requires compaction and cementation?
Sedimentary
200
What is the DV
What changes because of the IV
300
Balanced force....
causes an objects motion to stay still
300
Why was Wegner's theory rejected?
He could not explain why the continents moved
300
Divergent How does it move? What does it create? Example?
Moves apart New Crust Mid-Atlantic Ridge
300
How are metamorphic rocks formed?
Folding process that occurs during mountain building due to extreme heat and pressure
300
What is Newtons 1st Law of Motion
Things at rest stay at rest, things in motion stay in motion, unless acted upon by an unbalanced force. AKA Law of Inertia

On Warrior Olympics Day, the students were pulling with 285 N to the West. The teachers were pulling with 510 N to the East. What is the Net Force?
225 N
400
What 3 types of evidence did Wegner use to support theory?
land form, fossils, climate
400
Transform How does it move? Example? Does it destroy or create?
Grinds past (parallel) San Andrea's Fault Not destructive or constructive
400
How are igneous rocks formed?
Volcanic activity- melting, cooling and solidifying
400
What is Newtons 2nd Law of Motion
Acceleration of an object depends on its mass and the size of the force acting on the object. F=MA

On Warrior Olympics Day, the students were pulling with 285 N to the West. The teachers were pulling with 510 N to the East. What direction will the participants travel?
East

Give specific evidence Wegner used
land forms- mountains, coal lined up fossils- reptile in Africa and SA, plant in 5 different areas climate- tropical plant fossils found in Norway and glacier in SA
500
Convergent 3 types with examples
continent to continent- creates mountains (Himalayan) continent to ocean- creates subduction zone (Andes Mts) ocean to ocean- creates subduction zone (Japanese Island)

Describe how convection currents are the driving force behind rock cycle
Answer should include mantle

What is Newtons 3rd Law of Motion
For every action there is an equal and opposite reaction
