1. Wegner proposed that the continents were once joined together into one large landmass called Pangea and have since split and moved apart. His theory is known as the theory of
Seafloor Spreading
Continental Crust
Plate Tectonics
Gravitational Pull
2. Select the evidence used to support the theory of continental drift (4 answers)
Fossils matched on different continents
Bird migration patters
Climate (tropical plants found in arctic)
Rock patterns matched on different continents
Continents fit together like puzzle pieces
3. Harry Hess provided evidence for seafloor spreading which he theorized was responsible for continental drift. Which of the following evidences supported his theory of seafloor spreading? (3 answers)
Magnetic striping
Drilling samples (age of rocks)
Climate change
Temperature of the crust
Molten material found (rock formation)
4. What is the land feature that is formed when plates pull apart, allowing magma to rise creating new crust and pushing out the old crust, thus spreading the seafloor?
Rift Valley
Mid ocean ridge
Volcanic island arc
Subduction
5. This is a diagram of a
Volcanic island arc
Rift valley
Mid ocean ridge
None of the above
6. At which point would you find the youngest rock?
A
B
All rock is the same age
&. At which point would you find the oldest rock?
A
B
All rock is the same age
8. At point c, one plate is sinking and is being melted and recycled back into the mantle. This is called
Radiation
Convection
Conduction
Subduction
9. Which type of crust is more dense and will sink?
Oceanic
Continental
Both types of crust have the same density
10. Which type of crust is less dense and will sit on top?
Oceanic
Continental
Both types of crust have the same density
11. What land feature is formed over a subduction zone?
Trench
Volcanic island
Folded mountains
Rift valley
12. Why does magma rise at a mid ocean ridge?
Because it is more dense than everything around it
Because it is less dense than everything around it
Gravity
