In most cases, it comprises continental and oceanic lithosphere.
<h3>Why is it crucial to record the movement of plates and their boundaries?</h3>
Plate Boundaries and their movement are largely linked to volcanic activities and earthquakes. This means that they can be used to predict when any of the above-mentioned events may happen.
