4
What is foliation?
The science of metamorphic rocks
Stripes in metamorphic rocks that form when the rock melts and cools
Thin layers formed are bent and stretched during metamorphism
This layers of sediments that form metamorphic rocks
5
Name this plate boundary

6
What is the rock cycle
when rocks melt
when rocks cool down
when rocks break apart
when one rock can change into another type of rock
7
According to Wegener's theory of continental drift...
the continents were once together in a single landmass
earth has always had 7 continents
earth is slowly cooling and shrinking

Which is
not
true about Pangaea?
present day continents are identical to the Pangaea
it means "all lands"
it exisited about 225- 300 00 million years ago
