8.
Which explains that the continents were once joined together and over time they broke up and then drifted apart?
a)
Plate Tectonic Theory
b)

9.
This boundary is described by two plates moving away from eachother along the edges and separating. The resulting gap allows magma to rise and create new crust, forming new lithosphere. 
a)
Convergent Boundary 
b)
Divergent Boundary  
c)
Transform Boundary
