CLASSIFICATIONS OF VOLCANOES.

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..

CINDER CONE VOLCANO. This is built from ejected lava, rocks such as pumice, piled up one another. They have steep slope, wide crater, and is the most common and abundant type of volcano..

Why do volcanoes erupt?.

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..

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..

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..

[Audio] This causes a hue explosion which can be big enough to remove the top of the whole volcano..
