This guide explores the world's most famous volcanoes in a way that's perfect for kids ages 8–12, with a fun fact about each one and a free printable worksheet to learn more.
How does a volcano work?
Deep below the ground, rock is so hot it melts into a liquid called magma. When pressure builds up, the magma pushes up and bursts out of the volcano — and once it reaches the surface, we call it lava.
Some volcanoes ooze slow rivers of lava, while others erupt with a giant explosion.
The world's most famous volcanoes
Mount Vesuvius in Italy is famous for burying the Roman city of Pompeii — and about 3 million people live close to it today.
Krakatoa erupted so loudly that the sound circled the whole Earth about four times.
Kilauea in Hawaii erupts so often that its lava keeps adding brand-new land to the island.
Mount Nyiragongo in Africa has lava so runny it can race downhill as fast as a car.
Are volcanoes dangerous?
Volcanoes can be dangerous when they erupt, so scientists called volcanologists watch them closely to warn people in time. But volcanoes are also helpful — their ash makes soil rich for farming, and their lava builds new land.
Even famous Mount Fuji in Japan, quiet for over 300 years, is still counted as active.
