Cooling; The process that hardens magma and turns it into igneous rock. The cooling of magma can occur either underneath or on the earth's surface. E ... When magma reaches the surface through a volcano, it is called lava. When lava cools, it forms extrusive igneous rock. Weathering; The process by which rocks are worn down...

Igneous rock (from the Latin ignis meaning fire ) is one of the three main rock types (the others being sedimentary and metamorphic rock). Igneous rock is formed by magma (molten rock) being cool...
en.wikipedia.org/wiki/Igneous_rock
Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava. ... Lava (usually dacite or rhyolite) that is too sticky to flow far from its vent forms steep-sided mounds called lava domes.

A small rootless spatter cone that forms on the surface of a basaltic lava flow (usually pahoehoe) is called a hornito. ... A body of igneous rocks with a flat bottom and domed top. It is parallel to the layers above and below it. ... Lava is the word for magma (molten rock) when it erupts onto the Earth's surface.

Igneous rocks form by the cooling of magma (molten rock material beneath the surface) or lava (molten rock material extruded onto the surface). Magma which originates at depths as great as 200 kilometers below the surface consists primarily of elements found in silicate minerals along with gases, notably water vapor.

Igneous rocks are formed from the molten liquid minerals that lie below the earth's crust. ... Slowly cooling igneous rock will usually contain larger mineral crystals than igneous rock that cools more quickly. The magma that forms igneous rock beneath the surface of the earth can take thousands of years to cool.
