Tectonic Hazards

Question 1

What are the different plate margins?

Answer 1

-destructive
-constructive
-conservative
- collision

Question 2

What happens at a destructive plate margin

Answer 2

-Crust is destroyed
-dense oceanic plate is pushed under continental crust
-Pushes magna up
-creates composite volcano + earthquake

Question 3

What happens at a constructive plate margin

Answer 3

-Crust is created
-two plates move apart which allows magna sill the gap
-creates shield volcano earthquake

Question 4

What happens at a conservative plate margin

Answer 4

Two plates more alongside each other
Creates an earthquake
No earthquake

Question 5

What is an example o a conservative plate margin

Answer 5

San Andreas fault

Question 6

What is an example of a constructive plate margin

Answer 6

Mid Atlantic ridge

Question 7

What happens at a collision plate boundary

Answer 7

-Two plates of the same weight push against each other
-builds pressure
- push up to create a fold mountain
-no volcano
-earthquake

Question 8

True or false: destructive and constructive plate margins don’t have a volcano formed

Answer 8

False: its conservative and collision which don’t have a volcano

Question 9

What protection can buildings have to prevent damage from an earthquake

Answer 9

-rolling weight
-rubber shock absorbers
-latticework foundation
-fire resistant material
-reinforced lift shafts
-automatic shutters on windows

Question 10
