Volcanoes
Discover Earth's fiery mountains that blast hot lava, ash, and gases from deep underground
Active volcano erupting with lava flows, ash clouds, and glowing molten rock
Volcanoes are Earth's most spectacular fire-breathing mountains! These incredible geological features happen when hot, melted rock called magma finds its way to the surface from deep underground. When magma erupts from a volcano, it becomes lava - molten rock so hot it glows red, orange, and yellow like liquid fire.
How Volcanoes Work
Deep beneath our feet, magma forms in Earth's hot interior and rises upward because it's lighter than solid rock. When pressure builds up, the magma blasts through weak spots in Earth's crust, creating spectacular eruptions. Active volcanoes erupt regularly, dormant volcanoes are sleeping but could wake up, and extinct volcanoes will never erupt again.

The Ring of Fire around the Pacific Ocean contains about 75% of the world's active volcanoes! Hawaii's volcanoes create new land every day as lava flows into the ocean and hardens into rock. Some volcanoes grow underwater and eventually become new islands.
Types of Volcanic Eruptions
Gentle eruptions produce slow-flowing lava that people can sometimes walk away from. Explosive eruptions blast ash and rock high into the sky, creating towering clouds that can affect weather around the world. Strombolian eruptions shoot lava fountains like giant fireworks displays.
Volcanic ash can travel thousands of miles and affect airplane flights. Pyroclastic flows are incredibly dangerous avalanches of hot gas, ash, and rock that race down volcano slopes at highway speeds. Volcanic lightning creates spectacular electrical storms in eruption clouds.
Volcanoes remind us that our planet is alive and constantly changing - these fiery mountains show us the incredible power hidden beneath our feet and help create some of Earth's most beautiful and fertile landscapes!
