No, scoria is not a fine-grained rock. It is a volcanic rock with a vesicular texture, which means it has many tiny holes or vesicles on its surface, giving it a rough and porous appearance.
Scoria is a volcanic rock, basaltic in composition. It is a Greek word meaning cinder

Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
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.
What igneous rocks form on or very near Earth's surface?
Some common igneous rocks that form on or very near Earth's surface are basalt and scoria. Basalt is a fine-grained rock that often originates from volcanic eruptions, while scoria is a more vesicular or bubble-rich rock that forms from rapidly cooling lava on the surface.
A coarse-grained rock and a fine-grained rock probably had different .?
Cooling rates. A coarse-grained rock likely cooled slowly, allowing larger crystals to form, while a fine-grained rock probably cooled quickly, resulting in smaller crystals.
What is the orgin of fine grained igneous rock?
Fine-grained igneous rocks are formed when magma cools quickly at or near the Earth's surface, resulting in rapid crystal formation. This rapid cooling prevents large mineral crystals from forming, giving the rock its fine-grained texture. Examples of fine-grained igneous rocks include basalt and rhyolite.
How can you tell that scoria is an extrusive rock?
It is fine grained to glassy and contains vesicles.
Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
What is A coarse grained intrusive igneous rock that makes shield volcanoes?
scoria
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
What is meaning the grain of the rock?
fine grained or coarse grained
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.
Is rock smooth or rough?
Metamorphic rock can be coarse grained or fine grained.
Is quartzite rock fine grained course grained or medium grained?
Coarse
How does fine grained igneous rock form?
