As a result of convection currunts from the centre of the earth plates may move:
towards each other (Convergence)
away from each other (divergence)
or sideways aling adjacent boundaries (conservative plates)
Distribution of volcanoes, fold mountains and earthquakes.
In general plate boundaries are where most active zones of movement are.
It is where high mountains and ocean ridges are.
It is where volcanoes erupt and earthquakes occur.
The Pacific Ring of Fire and the Great East African Rift Valley for example are both found on plate boundaries.
Below is an interactive map of the world showing plate boundaries and their associated activity.
Click on the various activities such as earthquakes and volcanoes and you will notice that if you click the plate boundaries button, that these activities are mainly found along the boundaries of the major plates.
To show all earthquake and volcanic activity as well as the margins/boundaries of the world’s plates click on the “Click all” button.
NB This map uses flash and might not work on browsers like Opera Mini. Either find a device that can handle flash elements or just take our word for it. These activities are found along boundaries.
