Tectonic Plates<span>, Earthquakes, and </span>Volcanoes<span>. According to the theory of </span>plate tectonics, Earth is an active planet. Its surface is composed of many individualplates<span> that move and interact, constantly changing and reshaping Earth's outer layer.</span>Volcanoes<span> and earthquakes both result from the </span>movement<span> of </span>tectonic plates<span>.</span>
<span>I'm not sure I
completely understand what the question is asking for. When I look at
the plates, it looks like they all fit together like a giant puzzle.
They separated due to tectonic plates shifting over hundreds of years.
This was based on the theory that there was a supercontinent (one giant
landmass). I'm not sure how much this helps, but I hope it does. Good
luck!!
