Check out these fascinating volcano facts with National Geographic Kids! What is a volcano? Why does it erupt? And where can you find the world's biggest?
When a volcano erupts, hot gases and melted rock from deep within Earth find their way up to the surface. This material may flow slowly out of a fissure, or crack, in the ground, or it may explode suddenly into the air. Volcanic eruptions may be very destructive. But they also create new landforms.
The eruption released an avalanche of hot ash, gas, steam, and rocks that mowed down giant trees up to 15 miles (24 kilometers) away. When magma finds a way to escape from beneath the earth's...
A volcano is a mountain that has lava (hot, liquid rock) coming out from a magma chamber under the ground, or did have in the past. Volcanoes are formed by the movement of tectonic plates. The Earth's crust has 17 major, rigid tectonic plates. These float on a hotter, softer layer in its mantle.
A volcano is an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interior. When this material escapes, it causes an eruption.
A volcano is a mountain or hill with an opening. When a volcano erupts, magma is pushed up through the opening with great force. When magma reaches the Earth’s surface, it is called lava. Lava can be as hot as 2,200°F (1,204°C). Some volcanic eruptions are explosive. Lava shoots into the sky. Gas and hot pieces of rock and ash are also released.
Do you know how Volcanoes Work? What makes Volcanoes Erupt? Mother Earth is here to explain. Volcanoes are openings on the Earth’s surface where LAVA escapes...
