Pahoehoe lava. Molten pahoehoe lava flowing across a plain of solidified older lava. This thick ropy- looking lava may flow at speeds up to 50 kilometres per hour. Pahoehoe lava may harden in smooth sheets or it may ooze out and solidify into twisted rope-like formations. 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.
