In reference to the cooling of magma into rock, basalt is formed from rapid cooling.

∙ 13y agoNo, basalt is an extrusive rock, that means it came to the surface at an eruption. Compared to intrusive rocks (that stay in the earth), extrusive rocks cool fast.

∙ 12y agoFast if by basalt you mean a fine grain mafic rock.

When melted rock cooled on the Moon's surface it cooled to form what type of rock?
Basalt.
Is Scoria rock igneous?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
Which igneous rock has larger crystal one that cooled slowly or one that cooled quickly?
i thing becaUSE THEY ARE COOLED
Oceanic crust is composed of a volcanic rock that forms from quickly cooled lava called?
mainly basalt
What is the difference between a igneous rock and basalt?
basalt is an igneous rock. Igneous is one of the three main types of rock, (igneous, metamorphic and sedimentary) and means, "formed from fire" It includes any rock that cooled directly from a magma or lava state.
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
When melted rock cooled on the Moon's surface it cooled to form what type of rock?
Basalt.
Why does basalt have small sized crystals?
it cooled quick
What is the crystal size when magma cools entirely underground?
Cooled slowly underground the pseudo crystals of columnar basalt, such as the Giants Causeway in Ireland may be in a metre size range.
How does a basalt differ from gabbro?
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
Is Scoria rock igneous?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
Why does basalt rocks cool slowly?
Basalt cools off quickly because it is formed under water.
What are the difference between the sizes of the particles in granite with those in basaalt?
The crystals in granite, being intrusive in nature, will be larger than those in basalt, an extrusive igneous rock. Intrusive igneous rocks have cooled slowly from magma, extrusive rocks have cooled quickly from magma. Crystals grow larger from slow cooling magma.
Which igneous rock has the same chemical composition as basalt but a different grain size?
a hot dogs mother in laws mother to the horse in the backyard
What is cooled lava call?
Cooled lava is called a igneous rock once it has completely cooled and hardened. Some people just call it lava rock.
Which igneous rock has larger crystal one that cooled slowly or one that cooled quickly?

What are the colors and texture of both granite and basalt?
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.
