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.

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.
Magma is called lava after it erupts from a volcano. Different types of eruption result in different types of lava. For example, shield volcanoes such as Kilauea on the island of Hawaii produce large amounts of lava that is less viscous (less sticky) because it has less silica, SiO 2, in it.ava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. The source of the heat that liquefies the rock within the earth is geothermal energy.
