| A Volcano can be very deadly.1792 in Unzen,Japan a volcano collapsed and killed 14,300.Lava is molten rock. Lava forms between 150-50 below the surface of the earth that is called magma. When a volcano erupts it can create small islands and land forms. After the lava dries it creates mineral deposits and wonderful landscapes.The Hawii islands formed when a volcano erupted. Volcanos are caused when magma builds up in the camber below the volcano. The pressure in the camber forces the magma through the vent of the volcano and out comes lava. Lava can flow as fast as 40 miles per hour. The longest flowing lava known went as far as 51 kilometers. |
