Igneous rocks formwhen magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. How do igneous rocks...

There are three rock types that make up the Earth: metamorphic, igneous andsedimentary. As the Earth renews its crust, the sedimentary rocks become metamorphic and the metamorphic rocks become igneous. The igneous rocks can be broken up into sediments that then make them a part of the sedimenta...

"Cinders" are small pieces of igneous rock that have been blown from the vent of a cinder cone. They usually have a composition similar to basalt and contain numerous vesicles. Vesicles are small, round, bubble-like cavities that owe their presence to small amounts of gas that were trapped...
Does Obsidian exist? obsidian, igneous rock occurring as anatural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre...
