semi melted rock

Question 19

what is the two different types of plates

Answer 19

1 continental plates
2 oceanic plates

Question 20

what is a plate boundary

Answer 20

the line where two plates meet

Question 21

what is convection currents

Answer 21

when magma in the mantle is moved around in a circular motion it causes plates to move.

Question 22

explain convection currents

Answer 22

1 magma is heated in the core
2 it rises toward the crust
3 it cools down and moves sideways
4 this causes friction and pulls the plates
5 the magma cools and sinks back down
6 it is then repeated

Question 23

what is plate tectonics

Answer 23

the study of plates and their movement

Question 24

Answer 26

1 plates that collide have destructive boundaries.
2 crust is destroyed
3 the heavier plate melts back into the mantle
4 the lighter plate is lifted up to form Fold mountains.

Question 27

what happens when plates separate

Answer 27

1 plates that separate have constructive boundaries.
2 new crust is created
3 plates that separate form -
1 volcanic Mountains
2 Volcanic islands - iceland
3 mid ocean ridges - European plate and north American plate

Question 28

what happens when plates slide past each other

Answer 28

1 Plates that slide past each other has passive boundaries
2 they cause earthquakes and fault lines
3 the san Andreas fault in California is a fault line that is created when pacific plate is sliding past the north American plate

Question 29

what are the Andes

Answer 29

fold mountains that formed when the NAZCA plate collided with the south American plate
