What is the crystal size in a extrusive rock?
The crystal size in an extrusive rock is generally small to fine-grained due to rapid cooling of the magma outside the Earth's surface. This rapid cooling limits crystal growth, resulting in a compact and dense rock texture.
The crystal the size of an igneous rock is described as its what?
texture
What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
Does igneous rock texture refers to size?
please anyone else can answer this question I'm in hurry pls.
What is intrusive rock crystal size?
Intrusive rock crystal size refers to the dimensions of crystals that form within igneous rocks as they cool slowly beneath the Earth's surface. These crystals tend to be larger than those found in extrusive rocks, which cool quickly on the surface. The size can vary significantly depending on factors such as the cooling rate, mineral composition, and the environment of crystallization. Typically, intrusive rocks like granite exhibit larger, well-formed crystals compared to their extrusive counterparts.
Which crystal can help identify as igneous rock as intrusive or extrusive?
What is the effect of location on crystal size? Label the location of intrusive and extrusive igneous rocks on the diagram below. Then, illustrate the crystal size of the rock formed at that location in the appropriate callout circles.
What is the crystal size for extrusive igneous rocks?
Fine grained
What is the crystal size in a extrusive rock?
The crystal size in an extrusive rock is generally small to fine-grained due to rapid cooling of the magma outside the Earth's surface. This rapid cooling limits crystal growth, resulting in a compact and dense rock texture.
Is conglomerate intrusive or extrusive?
Neither. Conglomerate is a sedimentary rock. Intrusive and extrusive are descriptive terms used to classify igneous rocks.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
How can you determine if an igneous rock has had an intrusive or extrusive organ?
by the size of the crystals, big crystals intrusive, small crystals extrusive

What is the size of a crystal in an extrusive igneous rock?
Normally the crystals in extrusive igneous rock are small enough as to not be visible without magnification. The exception would be a porphyritic rock that has visible crystals dispersed in a fine-grained matrix. This type of rock represents a partial cooling of magma before expulsion by volcanism.
What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
What do extrusive igneous rocks look like?
The particle size (grain size--crystal size) in igneous rock is largely dependent on the amount of time spent cooling and solidifying from molten rock. If cooled quickly, crystals will have little time to grow. Slow cooling allows time for larger crystal growth.
Is lava intrusive or extrusive?
Lava is extrusive, meaning it forms on the Earth's surface as a result of volcanic activity. It cools rapidly and solidifies quickly into volcanic rock, such as basalt or obsidian. Intrusive rock, on the other hand, forms below the Earth's surface from magma that cools slowly.
