tectonic hazards

Question 1

destructive plate margin

Answer 1

plates move together if one plate is oceanic it sinks below the continental plate this can cause earth quakes and volcanoes if both are continentail form fold mountains

Question 2

constructive plate margin

Answer 2

plates move apart magma rises to the surface between the plates this creates volcanoes and mild earth quakes

Question 3

contructive plate margin

Answer 3

plates move past each other friction causes earthquakes but no volcanoes as there is no magama

Question 4

what are the types of hazards

Answer 4

tectonic :caused by plate movement e.g earthquakes and volcanoes
atospheric: liked to weather and climate eg tropical storms

Question 5

factors that might affect hazard risk

Answer 5

wealth : LICs are often more severly affected than HICs
population density : there are more people at risk in urban areas
physical environmental: relief ,proximity to coast climate etc

Question 6

monitoring

Answer 6

physical changes to help forecast tectonic hazards e.g monitoring earth tremors around volcanoes

Question 7

protection

Answer 7

actions taken before a hazards to reduce its effects e.g building earthquake proof buildings

Question 8

prediction

Answer 8

attempt to forecast when a hazard will strike
e.g monitoring used to make predictions earthquakes are almost impossible to predict but patterns of past events are considered

Question 9

planing

Answer 9

actions taken to enable comunites to respond to and recover from natural hazards e.g evacuation plans emergency supplied stores

Question 10

primary effect

Answer 10

inital impact on people and property caused directly by a hazard

Question 11

secondary effect

Answer 11

after effects that occur indirectly

Question 12

immediate response

Answer 12

action taken after a hazard has happend

Question 13

long term response

Answer 13

later reactions weeks months or years later
