Tell me about the lava

There are two types of lava fields in Hawaii. A'a is the broken lava and Pahoehoe is lava with the smoother surface. There is a third type of lava that is rarely seen, pillow lava, because it is found in the water at the base of a lava flow, and is caused when the hot lava hits the much cooler sea water.
