Answer 6

destructive zones

Question 7

Answer 7

constructive

Question 8

which type of crust is older?

continental

Question 9

Answer 9

constructive
destructive
conservative

Question 10

what is a conservative plate boundary?

Answer 10

crust is not made or destroyed, slides past each other

Question 11

what can occur at a conservative boundary?

Answer 11

friction can build up, causing strike slip creating an earthquake

Question 12

what occurs at a oceanic to oceanic constructive boundary?

Answer 12

mid ocean ridges

Question 13

what occurs at a continental to continental constructive boundary?

Answer 13

rift valley

Question 14

what occurs at a..
O-O
O-C
C-C
destructive plate boundary

Answer 14

O-O more dense one sub ducts (island arcs, trenches and volcanoes)
O-C oceanic sub ducts ( volcanoes and earthquakes)
C-C don’t sub duct so collide and form fold mountains
