There's three types of plate boundaries:
- Collision plate boundaries (where two or more plates of the same density collide )
- Adjacent plate boundaries (where two or more plates slide against each other)
- Subduction plate boundaries (where one or more plates with lesser density are subducting below the the plate that has bigger density).
I’m pretty sure you just add AB to BC, since they are all points on a line, those two segments add together to get the value of AC. Therefore, 12+16= 28, so AC=28
<span><span>The epicenter is the location where the greatest damage associated with an earthquake occurs.
</span>The distance of the epicenter of the earthquake from the seismic station is calculated according the difference in arrival time between the two types of seismic waves (S waves and P waves) . The further away an earthquake is, the greater the lag time between the detection of the S waves relative to the P waves.
