The map reveals a clear correlation between the locations of active volcanoes and earthquake zones, with both phenomena primarily concentrated along the edges of tectonic plates. The red dots representing volcanoes tend to cluster along the same lines as the yellow lines indicating earthquake zones. This pattern indicates that volcanic activity is often associated with tectonic plate boundaries, where plates converge, diverge, or slide past one another.
Earthquake zones appear as long lines on the globe because they correspond to the extensive boundaries of tectonic plates, which can extend for thousands of miles. These boundaries are not just single points but rather continuous regions where significant geological activities, like earthquakes and volcanic eruptions, occur due to the movement of the Earth's crust.
