may not want to leave
don’t believe the hazard will occur

Q

how are destructive plate margins formed?

A
continental meets continental 
no subduction of plates 
plates collide and cause mountains to forms 
earthquakes will occur
no volcanoes
17
Q

destructive plate movement continental with oceanic

A

more dense oceanic plate subducted below the continental plate
its taken down to the hot manle which will melt and become apart of the magama
new magma will pop out the other side and cause volcanoes

18
Q

conservative plate movement

A

two plate moving against each other causing friction that leads to earthquakes
no volcanoes

19
Q

constructive plate movement

A

plates moving the opposite direction
the magma becomes exposed as the plates separates causing it to reach the surface and cool down into new rocks.
can lead to rift valley

20
Q

(natural hazards)

what is a primary effect

A

the first effects pf a natural hazard or event the population. ( people or buildings)

21
Q

( natural hazards)

secondary effects

A

the after effect of a natural hazard, over a long period of time, days, months, years

22
Q

( natural hazards)

the immediate effect

A

how people react straight away

23

gross national income is $12,000 per person

24
