Answer 5

B-convergent

Question 6

There is a large area of slate. Which answer best describes what this tells you about what this area was like before it metamorphosed?
A-Parent rock: shale; interpretation: ocean floor
B-Parent rock: shale; interpretation: volcano
C-Parent rock: sandstone; interpretation: desert dune
D-Parent rock: sandstone; interpretation: mountains

Answer 6

A-Parent rock: shale; interpretation: ocean floor

Question 7
