They may be smooth and others may be rough. Smoothness/roughness is not a defining characteristic for igneous rocks.

What is the luster of igneous rock?
i think that igneous and metamorphic rocks uses luster because maybe they have it in them
What is the texture of Intrusive igneous rocks?
An igneous rock has two different textures. Extrusive rocks generally are smooth and glassy. Intrusive rocks are generally coarse
Which terms best describe igneous rocks?
Calloused rock, or Subtraceaneal rock. Also, Ephyloceaeoulical-Pharchylogenic Carboniferincean Postulate Aggrevations is a fancy way of saying it.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.

Are all igneous rocks rough?
Any igneous rock, if ground down to a smooth face and polished, will be smooth. Any igneous rock, if cut, will display a jagged edge. There is the potential for any igneous rock to be smooth or rough. A pumice may be an exception, but pumice isn't all igneous rocks. Most igneous rocks are not vesicular. Pumice will always be rough. Obsidian is naturally smooth, though not perfect. It has conchoidal fracture, so it may show a smooth face, but this is not always the case. Any rock that has been tossed in a river or on a beach for a few thousand years will be pretty smooth, no matter what it is (except pumice). A rock fresh from the quarry will nearly always be jagged and rough. Due to the crystalline texture of igneous rocks, most will naturally fracture in a way that leaves a rough face, if that is what you meant.
How you can tell an igneous rock from a sedimentary rock from a metamorphic rock?
Igneous Rocks are usually black and smooth because they ate formed by heat, sedimentary rocks are usually layered in color.
When molten rocks cools what rocks form?
igneous rocks
What kinds of rock make up continental crust?
Continental crustal rocks can be igneous, metamorphic, or sedimentary, but the vast majority are igneous, most closely resembling granite in composition.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Where are the two types of igneous rocks made?
Extrusive igneous rocks , Intrusive igneous rocks
