natural hazards

Question 1

Define constructive plate margin

Answer 1

Two plates moving apart, leaving a gap in the middle for magma to rise up

Question 2

Define destructive plate margin

Answer 2

A dense oceanic plate descends below a less than Continental plate
As the plate descends it is melted due to friction with the continental plate forming hot liquid magma
This can then rise through the cracks in the conscientious plate and form volcanoes

Question 3

Define conservative plate margins

Answer 3

two plates slip past each other, even opposite directions are at different rates in the same direction
This causes friction and energy which is released as an earthquake

Question 4

Define natural hazard

Answer 4

A natural process which could cause disruptions to humans or destroy property or pocessions

Question 5

Two factors affecting hazard risk

Answer 5

vulnerability
capacity to cope
