Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
Intrusive Extrusize Plutonic and Hypabyssal
.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

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.

Which statement is best supported by the information provided in the reference diagram of the Rock CycleinEarth's Crust?1. Igneous rocks are formed from eroded sediments 3. Metamorphic rocks are formed by the completeof metamorphic rocks. melting of any other rock.2. Sedimentary rocks are composed of intergrown 4. Rocks may be formed from other rocks by variouscrystals. processes.Answer: 4
