Small grained texture from small crystal size.
Probably limestone. :)
Basalt is an extrusive igneous rock, which means it has solidified from magma above ground.Read more: What_kind_of_rock_is_basalt
When lava cools and solidifies, it forms igneous rock. The specific type of igneous rock that forms from lava is called extrusive or volcanic rock, which includes examples like basalt and pumice. These rocks typically have a fine-grained texture due to the rapid cooling of lava on the Earth's surface.
It would form into the rock basalt, an extrusive, mafic, igneous rock.
The volcanic rock can be classified as basalt. Basalt is a fine-grained igneous rock that forms from the solidification of lava flows. The smooth texture and small holes, known as vesicles, are characteristic features of basalt.
Yes, Basalt is the most common extrusive rock
BASALT
A smooth, black rock is likely to be basalt. Basalt is an extrusive igneous rock that is commonly dark in color and has a fine-grained texture, giving it a smooth appearance.
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.

Cooling lava produces extrusive igneous rock, such as basalt.
Basalt is a type of rock, specifically an extrusive igneous rock that forms from solidified lava flows. It is composed mainly of minerals such as feldspar and pyroxene.

Extrusive rock of an igneous origin, formed from the cooling and solidification of lava. Typical examples include basalt, andesite and rhyolite.
