Small grained rocks have what texture?
Fine grained rocks are considered aphanitic.
Describe and explain the difference in the crystalline texture of volcanic rock and rock formed from an intrusion?
The texture of intrusive igneous rocks is phaneritic, which is characterized by coarse-grained large crystals that are visible to the naked eye. The texture of volcanic rocks, meanwhile, is porphyritic, which is characterized by fine-grained crystals.
Describe the textural difference between coarse-grained phaneritic and fine-grained aphaneritic rocks?
describe the textural difference between coarse-grained (phaneritic) and fine-grained (aphaneritic) rocks
Are grains in fine grained rocks easy to see?
No. In fact, in fine-grained rocks the grains are often impossible to see without a microscope.
What are two examples of fine-grained igneous rock?
Basalt and rhyolite are examples of fine-grained igneous rocks.
Are river rocks porous?
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.

Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
What are the types of volcanic rocks?
Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.
Are grains in fine grained rocks easy to see?
No. In fact, in fine-grained rocks the grains are often impossible to see without a microscope.
How do fine- grained igneous rocks from?
extrusive igneous rocks =/
Are extrusive rocks finely grained?
Yes extrusive rocks are fine grained because they cool down at a faster rate.
Which the following is a fine grained light colored extrusive igneous rock?
fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
