All igneous rock is the product of hardened magma from the upper mantle, except for igneous rock formed from extraterrestrial impacts.
magma cooling
Graphite can be found in all types of rock (igneous, metamorphic, and sedimentary). Although, it originates from igneous rocks, and is generally most economic in metamorphic rocks.
Igneous rock.
Extrusive igneous rocks , Intrusive igneous rocks
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.
All rocks are classfied as 1 of the following:Sedmintary Igneous and Metamorphic
Igneous, sedimentaty and metamorphic are all types of rocks. You would just write sentences to describe each, like "Igneous rocks come from volcanoes" and "Sedimentary rocks come from sediment."
igneous
Igneous Rocks are formed. Obsidian is a volcanic glass, go to wikepidiea and search "list of rocks" and it will come up with all the different igneous, metamorphic, and sedimentary rocks and what they are.
Magma
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

All volcanoes produce igneous rocks.
Igneous rocks
Yes!! All hot rocks are igneous rocks.

It comes from either metaphoric rocks or igneous rocks.
