No. In fact, in fine-grained rocks the grains are often impossible to see without a microscope.
False. Rocks with large grains that are easily seen are described as coarse-grained, not fine-grained. Fine-grained rocks have smaller grains that are not easily visible to the naked eye.
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.
Fine grained rocks are considered aphanitic.
Uplift and solidification
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.

it is fine grained because the grains that make it up are to small to see

Basalt and rhyolite are examples of fine-grained igneous rocks.
Large grains are easier to see than fine grains.
Fine-grained sedimentary rocks are typically smooth in texture due to their small grain size, which makes it difficult to discern individual grains with the naked eye. The smoothness can vary depending on factors such as the mineral composition and the level of compaction of the rock.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
extrusive igneous rocks =/
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.
