100
The main similarity between the inner and outer core.
What is they are both composed of iron and nickel?
100
This type of heat transfer occurs when there is direct contact between substances.
What is conduction?
100
Spelling of the last super-continent.
What is P A N G A E A?
100
The process where old, cold, dense crust sinks back into the mantle.
What is subduction?
100
Type of movement that occurs at convergent boundaries and the force associated with it.
What are collision and compression?
200
The main difference between the inner and outer core.
What is the outer core is liquid and the inner core is solid?
200
This type of heat transfer occurs through electromagnetic waves in empty space.
What is radiation?
200
Evidence type # 1 for continental drift.
There are three choices...
200
The underwater mountain chain with volcanoes where new crust is created.
What is mid-ocean ridge?
200
Type of movement that occurs at divergent boundaries and the force associated with it.
What are separation and tension?
300
Oceanic crust.
Which type of crust is more dense?
300
This type of heat transfer occurs through the particle movement because of a change in density.
What is convection?
300
Evidence type # 2 for continental drift.
There are three choices...
300
The location of subduction on the sea floor.
What is deep ocean trench?
300
Type of movement that occurs at transform boundaries and the force associated with it.
What are sliding past each other in opposite directions and shearing?
400
The lithosphere
What is the name of the layer of Earth that includes all of the crust and the upper mantle? (officially what the tectonic plates are made of)
400
The source of the heat that causes the convection currents in the mantle.
What is the core?
400
Evidence type # 3 for continental drift.
Thee are three choices...
400
The reason that there are magnetic stripes in the rocks next to a mid-ocean ridge.
What is the iron lined up with the magnetic north pole which changes location?
400
Location and description of the Ring of Fire.
What is the Pacific Ocean and a circle of earthquakes and volcanoes?
500
This is the squishy solid layer of Earth (like starburst) where the convection currents occur.
What is the asthenosphere?
500
Another example of convection.
What is...
500
Reason why Wegener's Theory of Continental Drift was rejected.
What is there was no mechanism identified to cause an entire continent to move.
500
The layer of Earth that is responsible for the magnetic field.
What is the outer core?
500
The reason there are more Earthquakes in California than Massachusetts.
What is California is on a fault line, plate boundary?
