Want this question answered?
fine grained or coarse grained
extrusive
Intrusive and extrusive factors of an igneous rock classify them. The other factors are if they are vesicular, coarse, fine grained, glassy, or very coarse
tat is very large grain .. its not having a fine texture..
Igneous rocks are formed by the cooling of lava (above Earth's surface) or magma (below). Rocks in general are classified by their mineral composition, texture, and origin. Igneous rocks all have the origin of molten material, there are two categories within this: intrusive and extrusive. Intrusive rocks formed below earth's surface and extrusive rocks above. Their mineral composition varies greatly and depends on each individual rock. The classification of igneous rocks in texture is linked to their origin. The texture of a rock is defined by its grain: can you see and feel the little rocks that make it up? If you can, that rock has a coarse grain, if you can't see the bits, it is fine grained. Intrusive igneous rocks are usually fine grained; extrusive, coarse grained.
Coarse is ruff/hard, and fine grain is smooth/ soft!

Basalt is an Extrusive Igneous Rock, it is a fine grained textured rock, While Gabbro is an Intrusive Igneous Rock and it has a Coarse grain texture.
Extrusive igneous rocks are usually fine grained.
Fine grains are harder than coarse grains
fine grained or coarse grained
Yes extrusive rocks are fine grained because they cool down at a faster rate.
No only fine grained as they cool quickly when out of the earths mantle so no time for crystals to form.
extrusive
Granite - coarse grained. Basalt - fine grained.
