5 A Day: Fruit of the Month: Persimmons. Persimmons origins go back to ancient China. Fate intervened in the 1880's when a United States Commander brought back a native Japanese persimmon variety to Washington, D.C. Now, persimmons are grown in California where hundreds of different varieties flourish. A Day: Fruit of the Month: Persimmons. Persimmons origins go back to ancient China.

As the super hot magma cools, it solidifies to form a rock and that rock is called igneous rock. When most people think of igneous rock they vision a volcano erupting pumice and lava. Igneous rocks form directly by crystallization from materials from a magma melt.
Non explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas). If the viscosity is low, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.Since it its a liquid, it flows downhill in response to gravity as a lava flows. Different magma types behave differently as lava flows, depending on their temperature, viscosity, and gas content.on explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas).
