Study Notes
- Volcanoes are vents in the earth's crust that release lava, rock fragments, and gases to the surface.
- Most volcanoes form when tectonic plates collide, move apart, or slide next to each other, causing magma to be squeezed out as lava.
- Volcanic eruptions can be extremely explosive, shooting superheated particles over 20 miles high and throwing giant boulders in the air.
- Some volcanoes have effusive eruptions where lava is slowly released to the surface, which are less dangerous than explosive eruptions.
- The text discusses a series of videos at Nat Geo Kids that explain what volcanoes are and how they form.
