1
Q
Where are volcanos located?
A
along plate margins, when plates are moving towards each other
2
Q
name 6 ways to predict volcanos
A
Seisometer
Tiltmeter
Gas readings
GPS
Thermal imaging
Eyesight
3
Q
Seisometer-
A
measures ground vibrations
4
Q
tiltmeter-
A
detect changes in volcanos slope, slope is steeper then there will eruption
5
Q
GPS-
A
monitors the change in shape and height of a volcano, cannot predict eruptions
6
Q
Gas readings-
A
if there is lots of toxic gases being produced then eruption on the way
7
Q
thermal imaging-
A
detect heat coming from magma or hot gases, cannot predict eruption
8
