Small grained texture from small crystal size.

What is most common type of extrusive rock?
Probably limestone. :)
What type of type rock is basalt?
Basalt is an extrusive igneous rock, which means it has solidified from magma above ground.Read more: What_kind_of_rock_is_basalt
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
You find a volcanic rock that is fairly smooth and only has a few small holes made when gas and water vapor escaped as the rock cooled you know that the rock can be classified as?
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.
What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Is basalt the most common intrusive rock?
Yes, Basalt is the most common extrusive rock
What is the most common type of extrusive rock?
BASALT
What type of rock is a smooth black rock?
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.
Which type of rock is formed as a result of lava cooling quickly?
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.
What type of texture does extrusive rock have?
coarser grained
What type of texture does extrusive rock?
coarser grained
What is most common type of extrusive rock?
Probably limestone. :)
What type of igneous rock that is made from lava?
Cooling lava produces extrusive igneous rock, such as basalt.
Is basalt a rock or mineral?
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.

What type of extrusive rock would form at a volcano?
Extrusive rock of an igneous origin, formed from the cooling and solidification of lava. Typical examples include basalt, andesite and rhyolite.
What is a igneous rock formed from magma?
basalt
