4.3. Types of Boundaries

Plate boundaries are very important and significant structural features. Nearly all seismic, volcanic and tectonic activities are confined to the plate margins. Boundaries are very distinct and easy to identify. They are associated with newly formed mountain systems, oceanic ridges and trenches. Plates are moving continuously and have relative direction of movement. Based on the direction of movement three types of plate boundaries can, easily, be identified (figure 7).
