volcano DLO

this term we were learning about the the earth and what happens my DLO is about 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. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. More than 80% of the earth's surface is volcanic in origin.
