LAVA

             When a volcano erupts, the magma goes up to the Earth’s surface. The magma that goes up is called lava. Lava is sometimes not dense. This type of lava is like honey. But sometimes it is dense. This type of lava is like honey with sugar.  

 

 

Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava. Lava can be thick and slow-moving or thin and fast-moving. Rock also comes from volcanoes in other forms, including ash (finely powdered rock that looks like dark smoke coming from the volcano), cinders (bits of fragmented lava), and pumice (light-weight rock that is full of air bubbles and is formed in explosive volcanic eruptions - this type of rock can float on water). Volcanic eruptions can cause great damage and the loss of life and property.
