Why are the crystals in pillow basalt smaller than the crystals in basalt that forms in the ground?
Pillow basalt is formed from solidifying lava which erupts under the surface of a body of water. Because of this, it cools much faster, allowing less time for crystal growth.
What is the name of A dark rock with small crystals formed on the surface of the earth?
Most generally, an igneous rock with small crystals formed from the cooling of lava on the surface of the Earth would be classified as basalt.
How will the size of crystals in granite be different to the size of crystals in basalt?
because they take longer to cool from the magma it is formed from
What does basalt have to do with volcanoes?
Basalt is an igneous rock that is formed after a volcano erupts.
Do large well -formed crystals cool quickly?
Large, well formed crystals form in solutions that cool rapidly. When solutions cool slowly, crystals are more likely to nucleate in higher numbers at the same time, leading to many very small and irregular shaped crystals.

Why does Granite take much longer to form than Basalt?
hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite
What is different from crystals underground than above?
Underground crystals are bigger where as crystals formed on the surface are smaller.

What rock has larger crystals than basalt and granite?
A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.
What are granite and basalt?
Both are igneous rocks, formed from the cooling and solidification of magma. Granite is a felsic, intrusive igneous rock, with visible well mixed mineral crystals. Basalt is a mafic, extrusive igneous rock, composed of darker mineral crystals, most of which are not distinguishable without the aid of magnification.
Is basalt formed from slow or rapidly cooling magma?
Basalt is formed from relatively rapid cooling magma.
What was the basalt and igneous rock formed by?
Basalt and igneous rocks were formed by what we would call magma/lava
How will the size of crystals in granite be different to the size of crystals in basalt?

What does basalt have to do with volcanoes?
Basalt is an igneous rock that is formed after a volcano erupts.

What is the meaning ofBASALTIC?
Pertaining to basalt; formed of, or containing, basalt; as basaltic lava.
