Why don't igneous rocks look like magma rocks if igneous rock is formed from magma?
Because that is the very definition of igneous rock.
How do igneous rocks can become sedimentary metamorphic and igneous rocks?
Igneous rocks can transform into sedimentary rocks through weathering and erosion, which breaks down the igneous rock into sediments that are then compacted and cemented together. Igneous rocks can also undergo metamorphism due to heat and pressure, resulting in the formation of metamorphic rocks. Igneous rocks can also melt and be recrystallized to form new igneous rocks through cooling and solidification.
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
Do igneous rocks that form inside the Earth's crust look different from the igneous rocks that form on the Earth's surface?
Yes. Igneous rock that forms on the surface will have small mineral crystals, or in some cases no mineral crystals. Igneous rock that forms below the surface will have larger mineral crystals, from the additional cooling time afforded by the insulating effects of the surrounding Earth material.
What are 7 elements igneous rock contains?
The seven main elements commonly found in igneous rocks are silicon, oxygen, aluminum, iron, calcium, sodium, and potassium. These elements make up the minerals that compose igneous rocks and give them their characteristic properties.

How do you classify igneous rocks?
Look at them. There shape, size, color and feel! Dont worry you will figure it out....
Why shouldn't you look for fossils in igneous rocks?
Well, Igneous Rocks are formed from Magma and the bones of an animal or a plant wouldn't have the time to become a fossil
Are the minerals which appear in metamorphic rocks largely the same as those in igneous rocks?
The minerals which appear are quite similar chemically but not physically. In metamorphic rocks, foliation can be seen-bands of rocks formed by great pressure, whereas in igneous rocks, this is never present because igneous rocks specifically need to have just previously melted, so therefore, these bands are disorganized and lost. Therefore, igneous rocks clearly don't seem to have any patterns unlike metamorphic rocks. Also, some minerals only form during metamorphism/melting+cooling. Therefore, the chemical composition is usually slightly different. E.g. Garnet is only formed under high-grade metamorphism-high temperatures and pressures. Also, the crystals sizes in igneous rocks depend on how long the rock has had to cool. So therefore, an igneous rock's crystals could be a lot bigger or smaller than a metamorphic rock's crystals. But then again, both rocks have interlocking crystals unlike sedimentary rocks, so in that way, at first glance, they can sometimes look very similar, (depending if it is intrusive of extrusive-metamorphic rocks will look a lot more like intrusive igneous rocks because of how the air affects the magma, (how magma looks when it cools), extrusive rocks look different, (blacker, smaller crystals etcetera).
What 3 things do you look at to key out igneous rocks?
color texture and mineral composition

How did igneous rocks get their names?
Igneous rocks got their name from the Latin word "ignis," which means fire. This is because igneous rocks are formed through the solidification of molten magma or lava. The name reflects the fiery origin of these rocks.
What does silver look like in rocks?
Black to dark Grey, in most cause, though very rare to fine silver seams !
