Cooled pahoehoe lava. Ferns growing out of cracks in a solidified flow of pahoehoe lava from the Kilauea Volcano,Hawaii. When molten,this thick ropy-looking lava may flow at speeds of up to 50 kilometres per hour. Pahoehoe lava is a type of basic lava with a low silica content,giving it a low melting point. This means the lava can travel great distances from the crater or vent from which it issued. The Hawaiian islands are entirely made up of volcanic rock,and the continuous eruptions of volcanoes such as Kilauea,mean the islands are still growing in size.
