Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
basalt, granite, pumice, and obsidian
Intrusive Extrusize Plutonic and Hypabyssal
in geology
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.
1. Marble ----- Limestone or dolostone 2. Gneiss ----- Granite or schist 3. Quartzite --- Sandstone 4. Schist ----- phyllite

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.
there are only 3 kinds of rocks, igneous, metamorphic, and sedementry
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.
