Consider the following facts:

1. Volcanoes are found primarily at convergent plate boundaries.
2. The Pacific Ring of Fire, the most volcano-rich area of the world, has examples of volcanoes formed by convergent plate tectonics.
3. Volcanoes are abundantly found where two tectonic plates slide past each other.

Which of the above is/are not true?

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example: the Mid-Atlantic Ridge has examples of volcanoes caused by divergent tectonic plates pulling apart. The Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another.
