Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.
Igneous Rocks - Rocks formed by crystallization from a melt (magma) types are: # Extrusive (volcanic) - produced when magma flows on the earth's surface # Intrusive (plutonic) - produced when magma solidifies at depth beneath the earth. eg.s are: 1)pumice. 2)Laccolith 3)Batholith 4)Dike 5)Sill
Parent rocks of metamorphic rocks can include sedimentary rocks, igneous rocks, and other metamorphic rocks. Some common parent rocks are shale, granite, and basalt. The mineral composition and texture of the parent rock influence the characteristics of the resulting metamorphic rock.
The layers of Earth's crust that consist mostly of igneous material are the uppermost layer, the oceanic crust, and the lowermost layer, the lower continental crust and lithospheric mantle. These layers are primarily composed of igneous rocks formed from the cooling and solidification of molten rock.

there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
Basically a bunch of rocks come together( are pressed together by heat and pressure) in a process called Lithification , those rocks can be either Sedimentary or Igneous rocks.

Precambrian rocks are the oldest rocks on Earth, dating back over 4 billion years. They often contain minerals such as quartz, feldspar, and mica, and can exhibit a wide range of colors and textures. These rocks can provide valuable information about the early Earth's geology and the processes that shaped our planet.
