Volcanoes - The Open Mind Academy
... Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava ...

Shield Volcanoes Composite Volcanoes Cinder Cone Volcanoes
... Cinder cone volcanoes are smaller than shield volcanoes and composite volcanoes. If the eruption contains thick magma, the gas pressure shatters the rock within the volcano into small pieces. In other cases, the lava in the air may harden and fall as fragments. These small pieces are called cinders. ...

... What is a volcano? A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava f ...
