Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.
What else can I help you with?
A coarse grained igneous rock with no pyroxene?
Granite is a coarse grained igneous rock without Pyroxene.
What name is applied to coarse grained felsic igneous rocks?
Granite is the name applied to coarse-grained felsic igneous rocks. These rocks are primarily composed of quartz, feldspar, and mica minerals, giving them a light color and coarse texture.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Describe the textural difference between coarse-grained phaneritic and fine-grained aphaneritic rocks?
Coarse-grained phaneritic rocks have mineral grains that are large enough to be seen with the naked eye, giving them a rough texture. Fine-grained aphaneritic rocks have much smaller mineral grains that are not individually visible, resulting in a smooth or fine texture.
What is the difference between exrusive an intrsive igneous rock?
Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained textures. Intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in coarse-grained textures.
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is the difference between coarse-grained and fine-grained?
Fine grained has larger crystals and coarse grained has smaller crystals

Where do coarse-grained igneous rocks form?
