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
.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.
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.

Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.

there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
obsidan,granite,marble,calcite
Limestone, sandstone, mudstone and chalk.
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.

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.
The five types of rocks are igneous (formed from cooled and solidified lava or magma), sedimentary (formed from compressed layers of sediments), metamorphic (rocks that have changed due to heat and pressure), sedimentary (formed from compacted and cemented particles), and organic (formed from the remains of living organisms).
