I find volcanoes fascinating!
Me too. It's crazy how the crust of the Earth ruptures and allows hot lava, ash and gases to escape.
It's weird how that all works. What causes a volcano to erupt?
The erupt due to the Earth's crust being broken into 17 major tectonic plates that float on a hotter, softer layer. 
That's all really interesting! I hear that they're formed because of the plates colliding with each other. Is that right?
Yes, but volcanoes can also form where this is stretching and thinning of the crust's plates.
I'd love to go and see a volcano in person! Any suggestions on which ones are safe to visit?
Northern Cordilleran Volcanic Province
The Northern Cordilleran Volcanic Province (NCVP), formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North America. This belt of volcanoes extends roughly north-northwest from northwestern British Columbia and the Alaska Panhandle through Yukon to the Southeast Fairbanks Census Area of far eastern Alaska, in a corridor hundreds of kilometres wide. It is the most recently defined volcanic province in the Western Cordillera. It has formed due to extensional
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic
