A volcano is a vent or fissure in the crust of a planetary-mass object that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift, the Wells Gray-Clearwater volcanic field, and the Rio Grande rift in North America. Volcanism away from plate boundaries most likely arises from upwelling diapirs from the core–mantle boundary called mantle plumes, 3,000 kilometres (1,900 mi) deep within Earth. This results in hotspot volcanism or intraplate volcanism, in which the plume may cause thinning of the crust and result in a volcanic island chain due to the continuous movement of the tectonic plate, of which the Hawaiian hotspot is an example. Volcanoes are usually not created at transform tectonic boundaries where two tectonic plates slide past one another.

One of the best places to start your volcanic journey is in Hawaii. The Hawaiian Islands were formed by a series of volcanic eruptions, and the evidence of this explosive history can be seen everywhere you go. Head to Hawaii Volcanoes National Park on the Big Island to witness the active Kilauea volcano up close – you might even catch a glimpse of the lava flowing! The park also boasts a variety of hiking trails that wind through lava fields and lush rainforests, offering a unique perspective on the island's explosive past.

If you're looking for a different kind of volcanic experience, head to Crater Lake National Park in Oregon. This stunningly beautiful park is centered around the deepest lake in the United States, which was formed over 7,000 years ago when a massive volcano collapsed in on itself. Today, visitors can hike around the rim of the crater, take a boat tour of the lake, or simply marvel at the crystal-clear water that seems to change color with the light.
