Hazardous Environments

Question 1

Constructive Plate Boundary

Answer 1

Two continental plates
Plates move apart
Earthquakes and shield volcanoes can form

Question 2

Destructive Plate Boundary

Answer 2

Continental and Oceanic
Plates pushed together
Earthquakes, composite volcanoes, and tsunamis can form

Question 3

Conservative Plate Boundary

Answer 3

Any type of plate
Plates slide together in same direction
Only earthquakes can form

Question 4

Collision Plate Boundary

Answer 4

Continental and Continental
Plates pushed together
Only earthquakes can form

Question 5

Answer 5

Formed on destructive plate boundary
Violent eruptions
Thick, slow-moving lava
Narrow with steep sides
Layers of ash and lava

Question 6

Shield Volcanoes

Answer 6

Formed on constructive plate boundary
Gentle eruptions
Thin, quick-moving lava
Wide with gentle slopes
Only layers of lava

Question 7
