A volcano is a mountain that forms when magma escapes from underground, erupting through the surface of the Earth. It consists of an opening in the crust where molten rock and gases are released. The largest volcano in New Zealand is Lake Taupo, which last erupted in 186 AD, while the most active is Mt. Ruapehu. Indonesia has the most volcanoes of any country due to its location along the Pacific Ring of Fire.

• A volcano is a landform (usually a mountain) where

• In simple terms a volcano is a mountain that opens
downward to a pool of molten rock (magma) below the
surface of the earth. It is a hole in the Earth from which
molten rock and gas erupt.
