Answers
1
What are the two main types of crust?
Land and islands
Land and sea
Continental and oceanic
continents and sea
2
The name of the Super-continent which all of the contents once formed is
Pangaea
Pacifica
Laurasia
Gondwana
3
What is Seafloor Spreading?
plates coming together to form trenches
when the oceans get larger
occurs @ ridges where new crust forms & graduallymoves away
the gradual erosion of water forming canyons
4
Why was Wegener's Continental Drift theory rejected by scientists in the early 1900s?
Wegener had no evidence.
Wegener was a stupid stupid man.
Wegener could not explain how the continents moved.
The other scientists did not understand it.
5
What is the result of seafloor spreading?
ridges
mountains
trenches
volcanoes
6
Which one of the following statements is
NOT
evidence supporting Continental Drift?
Rock layers and formations line up on matching coastlines
Fossils of same animals found on different continents
Continental coastlines fit together like puzzle pieces
Seafloor Spreading where older rock is found far from ridge

Inner Core
Asthenosphere/Mantle
18
Crust is ____________ at convergent boundaries with continent to oceanic plate collisions
Destroyed
Created

19
Sea floor spreading is causing
the Pacific ocean gets larger & the Atlantic Ocean to shrink
the Atlantic & Pacific ocean stay the same size
the Atlantic ocean gets larger & the Pacific Ocean to shrink
the Atlantic ocean gets hotter & the Pacific Ocean cooler
20
Subduction is when:
2 plates converge & lighter plate slides under denser plate
2 plates diverge & denser plate slides under lighter plate
2 plates diverge & lighter plate slides under denser plate
2 plates converge & denser plate slides under lighter plate
21
What forms at Divergent Boundaries?
Mountains
Ridges
Earthquakes
Trenches
