puzzle like fit of all the continents
same animal fossils on different continents
3
Oceanic crust is ___________than continental crust
more dense
more hot
less hot
less dense
4
type of volcano that forms on the side or crater
shield volcano
composite volcano

none of the above
5

where the earth is the hottest
where the edges of the continents are
nothing, it looks random
where the plate boundaries are

transform plate boundary
convergent plate boundary
none of the above
divergent plate boundary
8

?
convergent boundary
transform boundary
divergent boundary
none of the above
11

divergent plate boundary
none of the above
13
Name the plate boundary in the illustration.
none of the above
divergent plate boundary

convergent plate boundary
14
What do scientists believe is the force behind the plate tectonics theory?
gravity slab pull
the Sun's gravity
convection currents
the movement of the planets
15
How can crust disappear at the edge of a boundary?
new crust is being added to the other edge of the boundary
