yes because of fast cooling rate
Volcanic rocks form from lava that cools quickly on the Earth's surface, while plutonic rocks form from magma that cools slowly beneath the surface. Volcanic rocks have fine-grained textures, while plutonic rocks have coarse-grained textures. Volcanic rocks are often found in volcanic regions, while plutonic rocks are typically found deeper underground.
Volcanic rocks form from lava that cools quickly on the Earth's surface, while plutonic rocks form from magma that cools slowly beneath the surface. Volcanic rocks have fine-grained textures, while plutonic rocks have coarse-grained textures. Additionally, volcanic rocks often contain gas bubbles and may have a glassy appearance, while plutonic rocks are typically more crystalline.
Fine grained rocks are considered aphanitic.
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.
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.
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.

Basalt and rhyolite are examples of fine-grained igneous rocks.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Basalt and granite are the most common types of rocks that make up igneous rocks. Basalt is a fine-grained volcanic rock, while granite is a coarse-grained intrusive rock.
Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.

extrusive igneous rocks =/
Yes extrusive rocks are fine grained because they cool down at a faster rate.
Fine grained rocks are considered aphanitic.
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
