∙ 12y agoAn igneous rock is a rock that is formed by volcanos. Over 85% of rocks on the earth are igneous. These rock can be classified into felsic or mafic depending on the lava or magma is was made from. Igneous rocks can also be classified into intrusive or extrusive. If intrusive then the rock cooled slowly and created big crystals. If extrusive then the rock cooled slowly outside of the volcano, creating small crystals. Hope this helps!

∙ 14y agoIgneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).

Is felsic porphyritic extrusive?
Some felsic rocks are and some are not. The term felsic is a description of an ingeous rock's composition, not its texture or where it occurs.
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
Is felsic an intrusive or extrusive igneous rock?
It can be either. "Felsic" is not a specific type of rock but a general description of an ingeous rock's composition indicating high levels of silica and alkali feldspars.
What is the dirrerence between extrusive and intusive rocks give an example of each?
The difference between extrusive and intrsive rocks are thatextrusive rock is a ingeous rock and formes by lava that erupes onto earth surface, and that intrusive rock is igneous rocks that hardenes beeatg earth's surface.
Which process changes ingeous rocks into metamorphic?
Answering "What process changes igneous rocks into metamorphic types?"Igneous rocks convert into metamorphic due to extreme pressure and heat, which can come from magma/lava or the movement of tectonic plates. For example, the igneous rock basalt eventually turns into the metamorphic rock granulite.
Is magma like a ingeous rock?
yes
What are the examples of ingeous rocks?
Obsidian, Granite, and i believe slate

What isigneous rock at the earth's surface that is weathered and wears away?
extrusive ingeous rock
Why cant fossils be found in ingeous rock?
Its extreme heat and pressure would destroy it.
Why are molten rocks found near volcanoes?
Molten rock is magma when cooled turns into an ingeous rock
What do ingeous rocks form from?
a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
