What Process adds new material to the ocean floor
Seafloor Spreading
100
The discovery of seafloor spreading helped or rejected the idea of continental drift? and how
Helped, showed how plates moved
100
Who discovered how material is added to the seafloor
Harry Hess
100
The idea that the earths plates are in slow constant Motion
Plate Tectonics
100
Whats going on at A
Molten Material
100
_______ Space
Blank
200
What is happening in the mantle that makes new floor be added to the ocean floor
Convection Currents
200
What are the 3 types of evidence Hess used for SFS
-Magnetic Striping
-Molten Material
-Drilling Samples

What year was Plate tectonics proposed and accepted?
(Within 5 years)
1960
200
What is happening at B
Convection Currents in the Mantle move the crust
200
I knew you were ________
Trouble
300
What is at C?
Mid Ocean Ridge
300
How is molten material good evidence for seafloor spreading
Molten Material proves that new ocean floor was being made and disproes the idea that all of the ocean floor was made at the same time

Continental Drift

What 3 theories is plate tectonics based on
Continental drift
Convection Currents
Seafloor Spreading

What PROCESS happening at C
Seafloor Spreading

______ Story

Process that recycles old crust back into the mantle
Subduction
400
Acquiring rock samples and determining the age of rock is good evidence for Sea Floor Spreading because..
Taking rock samples near and far from the mid ocean ridge proved that the ocean floor was different ages. This means it was not all made at the same time.

But _________ I love him
Daddy

What land feature is at D
Deep Ocean Trench
500
Magnetic striping is good evidence for Sea Floor Spreading because...
Magnetic striping of the ocean floor proves that not all of the ocean floor was made at the same time but rather piece by piece over time.
