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?
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.
23 Ιαν 2015 · When the lava is escaping from the volcano, the volcano is said to be 'erupting'. Eruptions can be started by explosions caused by water or gas coming into contact with the liquid rock under the ground.
14 Αυγ 2018 · 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.
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.
