Volcanoes

We have been learning about volcanoes in the Tigers group.

How volcanoes are made.

Volcanoes form where lava comes up a crack in the earth's crust. The lava cools and turns into hard rock. It builds up and forms a volcano. Volcanoes are made out of ash and lava and rocks.

Under sea volcanoes.

When lava hits water it makes obsidian or cobblestone.

When an under sea volcano erupts it may form an island.

Lava and the centre of the earth.

 

Some people know where to find most volcanoes by learning about the movement of the earth.

 

Gets hotter when near to the centre of the earth.

Volcano types. there are six types of volcanoes, fissure, shield, dome, ash-cinder, composite and caldera.

Dormant-don't know if it will erupt.

Active-can erupt at any time.

Extinct-will not erupt.

Have you seen a volcano?
