What is the crystal size for extrusive igneous rocks?
Fine grained
Are in intrusive rocks fine grained?
No, intrusive rocks are typically coarse-grained because they form from magma that cools slowly beneath the Earth's surface, allowing larger crystals to develop. In contrast, extrusive rocks, which form from lava that cools quickly on the surface, are usually fine-grained. Thus, the grain size is a key distinguishing feature between intrusive and extrusive 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.
Is shale fine-grained or coarse-grained?
shale is fine grained
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
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
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.
What are the properties of extrusive rock?
Extrusive rocks are formed from magma that cools quickly on the Earth's surface, resulting in small or no crystals. They typically have a fine-grained texture and may contain gas bubbles. Examples of extrusive rocks include basalt and rhyolite.
What grain type is found in extrusive igneous rocks?
Extrusive igneous rocks are usually fine grained.
What is the crystal size for extrusive igneous rocks?
Fine grained
Are river rocks porous?
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.
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.
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 types of extrusive rock?
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.
How does extrusive differ from intrusive?
Extrusive rocks form from lava cooling on the Earth's surface, leading to rapid cooling and fine-grained texture. Intrusive rocks form from magma cooling beneath the surface, resulting in slower cooling and coarse-grained texture. This difference in cooling rates gives extrusive rocks their characteristic fine-grained appearance and intrusive rocks their coarse-grained appearance.
What rocks are extrusive?
Extrusive igneous rocks are formed by magma. The magma is crystallized after being pushed to the surface of the Earth. They usually are very fine grained. A really common extrusive rock would be Basalt.
