They are rocks formed from lava at or near the surface. Basalt is a typical fine-grained extrusive igneous rock, composed of mineral crystals that require magnification to see. The fine-grained texture is due to rapid solidification of the lava which leaves little time for large mineral crystal formation.

Which would weather faster a fine grained or a coarse grained igneous rock?
fine grained rock will weaher faster thatn the course grained rock
Is limestone coarse grained or fine grained?
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
Is metamorphic rock rough or smooth?
Metamorphic rock can be coarse grained or fine grained.
Is fine grained sedimentary rock smooth?
Yes. Fine grained means the grains in the rock are very small. The smaller the grains, the smoother the rock.
What are three types of sedimentary rock texture?
Coarse grained, Medium grained, and fine grained.
The moon is made of rock called what?
The moon is made of basalt rock. Basalt rock is igneous, dark colored, and fine grained. Similar rock can be found in Antarctica and Hawaii.
Basalt is an example of a n?
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
Which would weather faster a fine grained or a coarse grained igneous rock?

What does basalt?
A dark fine-grained volcanic rock that sometimes displays a columnar structure
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Is limestone coarse grained or fine grained?
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
What is meaning the grain of the rock?
fine grained or coarse grained
What is an andesite?
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
Is rock smooth or rough?

Is quartzite rock fine grained course grained or medium grained?
Coarse
How does fine grained igneous rock form?
when the lava cools quickley it is fine-grained
Is metamorphic rock rough or smooth?
