Question 13

Oceanic Plates

Answer 13

New, thin plates made of Granite

Question 14

Convergent (destructive) Plate boundary

Answer 14

When two plates (oceanic and continental) move towards each other, the oceanic plate to move under, causing earthquakes and composite volcanos

Question 15

Divergent (constructive) Plate boundary

Answer 15

When two plate move away from each other, causes calm earhtquakes and volcanoes.

Question 16

Conservative Plate boundaries

Answer 16

When two plates move vertically but in other directions, causes very violent erthquakes but no volcanoes.

Question 17

Collision Plate boundaries

Answer 17

When two Continental (same density) plates move together. They forcing each other up, causes volcanoes, earthquakes and fold mountains
