Introduce your students to magma, lava, and volcanic eruptions through this classic, jurassic science experiment. Your students won’t want to miss the show, either!
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...
During a volcanic eruption, hot melted rock called magma escapes from a vent, or opening, in Earth’s surface, or crust. Magma released from a volcano is known as lava. Fresh lava ranges from 1,300 to 2,200 °F (700 to 1,200 ° C) in temperature. It glows red as it flows out of the volcano’s opening.
A volcano is a type of mountain that caves downwards to a pool of molten rock, which is below the Earth’s surface. During a volcanic eruption, pressure builds up underground due to the formation of magma, which is molten rock mixed with gas. The pressure causes gases and rock to shoot up through the opening and spill over with lava fragments.
WHAT IS A VOLCANO? Volcanoes are openings in the Earth’s rocky Core crust which allow hot molten (melted) rock, ash and gas to escape from below the surface. Volcanoes form when parts of the Earth’s solid mantle melts to form pockets of hot liquid rock called magma. This magma collects in large pools deep underground known as magma chambers.
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?
14 Αυγ 2018 · Volcanoes can be dangerous—especially to the millions of people around the world who live near one. When a volcano erupts, lava, hot ash, steam, and rocks are released. In addition, volcanic eruptions can cause other natural disasters. These include landslides, mudslides, earthquakes, and tsunamis.
