Which is older igneous or sedimentary?
Igneous rocks are typically older than sedimentary rocks. Igneous rocks form from the cooling and solidification of molten material (magma or lava), which usually happens before the formation of sedimentary rocks through processes like erosion, deposition, and compaction.
Igneous rocks sedimentary rocks metamorphic rocks are made of?
Igneous rocks are formed by a solidified magma. There are hundreds of different minerals that those rocks may comprise. The mineralogy of igneous rocks is defined by their chemical composition and the pressures and temperatures at which they solidified. Most igneous rocks contain mostly silicates (e.g. quartz, feldspars, mica, pyroxenes, amphiboles, olivine). Sulphides (e.g. pyrite, chalcopyrite, galenite etc.) and titanite, monazite, zircon etc. are common minor components. Some more exotic igneous rocks known as carbonatites are largely made up of carbonate minerals that crystallized out of a carbonate magma.
Why fossils are rarely found in metamorphic and igneous rocks?
This is because igneous and metamorphic rocks are created under extreme heat and pressure, and very few fossils would survive those conditions. The most common forms of fossils are those found in sedimentary rocks.
What kind of rock do fossils form?
Sedimentary rock, its rarely found in metamorphic and never found in igneous rock because it would make the fossil of the animal worped and changed. It wouldn't be with the original form on metamorphic and igneous would destroy the whole fossil.
Why are igneous rocks also called as fire rocks?
Magma erupts from volcanic eruptions and on reaching earths crust it is called lava and solidifies by cooling. So they are referred to as primary rocksIgneous rocks are the rocks which are the original/initial rocks, as they were formed first.eg. sedimentary rocks are formed by denudation of a preexisting rock.and metamorphic rocks are also formed by metamorphism of preexisting rocks.Igneous rocks are also known as parent rocks because all other rocksare formed or derived from them.
How are rocks useful in everyday life?

How are metamorphic used in everyday life?
rocks and minerals
How are gamma rays used in everyday life?
While we are all exposed to them a little form rocks and from outer space, they are NOT used in everyday life. Gamma rays are dangerous.
What are everyday things that exist by science?
What are three examples of science that occur or exist in everyday life and why
What are three examples three examples of science in your everyday life?
Everyday life has a myriad of examples of science. Computer science is important, as well as medical science. Another is genetics that are assisting the planet in world hunger.

Why do rock fossils form in sedimantry rock and not in igneous rock?
Fossils usually form when the remains of an organism are buried gently under sediments which later turn into stone. Intrusive igneous rocks form at depths within Earth where no life is found. Extrusive igneous (volcanic) rocks are so hot when they are deposited that any remains of organisms are usually incinerated. Fossils do occur in volcanic rocks, but very rarely.
What size grains do igneous rocks have?
The bigger it is, the slower it cools and vise versa. -Life Science last year; Lots o' geology.

What type of rock is igneous?
Igneous rocks are formed by the hardening of molten lava from a volcanic erruption. These rocks are also categorised by two types. One that is formed by rapid hardening / solidifying of lava eg. Granite and one that is formed by slow hardening eg. Basalt. These rocks have high density, strength and are bulky.
What are the three examples of changes in life that are supported by evidence of rock layers?
