How are islands formed? Islands seemingly pop up out of the ocean. New land is created through magma/lava oozing out of the ocean crust and forming seamounts (large amounts of magma/lava piled on top of each other) When the pile gets tall enough so that it is taller than the water - an island is born. As the magma/lava continues to flow, the island continues to get taller and wider. You can see streams of hardened lava down the sides of the volcano where the vegetation has been destroyed by the lava.
Clouds pass over Papua New Guinea's Manam Volcano on June 16, just as a thin, blue-gray volcanic plume issues from the summit. The bright white clouds may result from water vapor from the volcano, or they may be unrelated to the volcanic activity. This picture was captured by an imager aboard NASA's Earth Observing-1 satellte, also known as EO-1.
