Question 6

Types of plate margins:

1-2-3

Answer 6

1) Destructive - oceanic forced under continental causing volcano
2) Constructive - plates move apart and volcano formed
3) Conservative - when plates slide past each other and shock waves produce earthquake

• Deep sea trenches

Question 8

Landforms at constructive boundaries

Answer 8

• Rift valleys
• Volcanoes
• Ocean ridges

Question 9

3 types of earthquake waves

Answer 9

• P-waves, fastest but least damage
• L-waves, large amplitude, on surface, cause significant damage
• S-waves, ground shakes violently
