What else can I help you with?
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
Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
What is the cooling environment of a fine grained igneous rock?
A fine-grained igneous rock forms from magma cooling quickly at or near the surface of the Earth. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture with small mineral grains. Examples of fine-grained igneous rocks include basalt and rhyolite.
How fast do coarse grained and fine grained rocks cool?
If the rocks are igneous then in general:- Coarse = slowly. Fine = fast. However if the rocks are metamorphic or sedimentary then grain size has nothing to do with cooling and indicates other things.
What kind of rocks make up the most of the igneous rocks?
Basalt and granite are the most common types of rocks that make up igneous rocks. Basalt is a fine-grained volcanic rock, while granite is a coarse-grained intrusive rock.
What are two examples of fine-grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
Which igneous rocks are fine grained to due to fast cooling?
Extrusive igneous rocks are fine grained due to fast cooling. They cool at a faster rate than most igneous rocks.
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
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 grain type is found in extrusive igneous rocks?
Extrusive igneous rocks are usually fine grained.
What are 2 fine-grained igneous rocks?
Granite and Bassalt
What is the origin of the fine grained igneous rock?
Uplift and solidification
What is the crystal size for extrusive igneous rocks?
Fine grained
What is the orgin of fine grained igneous rock?
Fine-grained igneous rocks are formed when magma cools quickly at or near the Earth's surface, resulting in rapid crystal formation. This rapid cooling prevents large mineral crystals from forming, giving the rock its fine-grained texture. Examples of fine-grained igneous rocks include basalt and rhyolite.
What are types of extrusive igneous rocks?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
What are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.
