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.

Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
What igneous rock that formed from lava that erupted into earths surface are called?
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.

Are all igneous rocks formed inside the earth?
Igneous rock can form inside the Earth or on its surface, from the solidification of molten rock.
Is it true that igneous rocks form only beneath earths surface?
It is not true. Extrusive rock forms on the surface from solidifying lava.
What is igneas rock?

Where do you find coarse grained rock?
true mf
What is igneas rock origin?

What type of rock forms when lava cools very quickly?
igneous with small crystals. Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt. Igneous rocks are formed by magma (inside the earth) or lava (outside earth) that cools and hardens. Extrusive rocks are rocks thathave exited the earths surface.
