Igneous rocks are formed from the solidification of molten rock material. There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below Earth's surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above Earth's surface. Pictures and brief descriptions of some common igneous rock types are shown on this page.

What are 3 basic types of rock?
The three basic types of rock are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and cementation of sediments. Metamorphic rocks are created from the alteration of existing rock through heat and pressure.
What this different between acid igneous rock and basic igneous rock?
Acidic igneous rocks have a higher silica content and lower magnesium and iron content compared to basic igneous rocks. Acidic rocks are typically light in color and have a higher viscosity, meaning they are more resistant to flow. Basic rocks, on the other hand, have a lower silica content, higher magnesium and iron content, and are typically dark in color with lower viscosity.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
When magma is cooled it becomes what?
Cooling and solidifying magma turns into igneous rock.
What kind of rock is formed after a volcano erupts?
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
