Extrusive igneous rocks are formed on the surface of the earth. These rocks are formed as a result of a volcanic eruption. Most have a fine grained texture made of small crystals due to rapid cooling. However, some of the lava cools so quickly that no crystals have time to form. An example of this type of rock is obsidian, commonly called black glass or volcanic glass.
Hurricane Sandy (unofficially known as Superstorm Sandy) was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season, and the second-costliest hurricane in United States history.
