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.
Granite is a coarse grained igneous rock without Pyroxene.
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.
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.
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.
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.

A peridotite is a dense, coarse-grained igneous rock
Yes. Exactly, they do have both, fine grained and coarse grained rocks.

Coarse-grained igneous rocks are formed when magma cools slowly deep inside the Earth. Creating big crystals in them.
