What are Some Types of Lava Formations?
When volcanoes explode, various interesting lava formations and features are often created. The most simple is new land — created when volcanoes dump magma into the sea and it cools, forming rock. This process is ongoing in the Hawaiian Islands, where new land is created every year. Entire island chains, such as the Hawaiian Islands and much of Indonesia, are huge lava formations created tens of millions of years ago. Another type of lava formation are lava tubes, which are formed when lava flows over the ground and the top of the flow hardens, sealing in super-hot lava which flows quickly through the tube. Lava tubes can either be active, as some are on the island of Hawaii, or dormant, as most around the world. These tubes are unique cave-like channels that can be explored by the adventurous. Their ceilings occasionally have lavacicles, lava formations created when hot lava splashes against the ceiling and drips down into a stalactite shape as it cools.
