CLASSIFICATIONS OF VOLCANOES.
Scene 22 (3m 22s)
SHIELD VOLCANO. This is formed by the accumulation of lava oozes out from the volcano. Because the lava that creates shield volcanoes is fluid and flows freely, a broad, slightly doomed structure that resembles a warrior’s shield is formed..

Why do volcanoes erupt?.
Scene 34 (5m 4s)
Why do volcanoes erupt?. A volcano erupts when magma gases finds way to escape, so they burst to the surface through a vent. It can be gentle or very violent..
Scene 35 (5m 16s)
LEVEL OF ERUPTION. If it is easy for the gases to escape, then the eruptions is very gentle. However, the lava is very runny and moves faster..
Scene 36 (5m 32s)
LEVEL OF ERUPTION. Gas builds up and lumps of rock (bombs) and ash burst out of the volcano. This makes the lava thick and sticky..
Scene 37 (5m 43s)
[Audio] This causes a hue explosion which can be big enough to remove the top of the whole volcano..
