What are some facts about volcanoes?

Here

Explanation:

An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls. More than 80% of the earth's surface is volcanic in origin. The seafloor and some mountains were formed by countless volcanic eruptions. Gaseous emissions from volcano formed the earth's atmosphere.

The word volcano originally comes from the name of the Roman god of fire, Vulcan.

Volcanoes are usually located where tectonic plates meet. This is especially true for the Pacific Ring of Fire, an area around the Pacific Ocean where over 75% of the volcanoes on Earth are found.

Volcanoes can be active (regular activity), dormant (recent historical activity but now quiet) or extinct (no activity in historical times and unlikely to erupt again). While these terms are useful, scientists are more likely to describe volcanoes by characteristics such a how they formed, how they erupt and what their shape is.
