i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
because they take longer to cool from the magma it is formed from
The crystals in basalt that formed underwater are typically smaller due to the rapid cooling of lava when it comes into contact with water. This rapid cooling prevents the crystals from having enough time to grow larger, resulting in a finer-grained texture. In contrast, basalt that cools on the ground generally does so more slowly, allowing for the formation of larger crystals. This difference in cooling rates is a key factor in the size disparity of the crystals.
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.
Although they are both igneous rocks which have solidified from magma, granite is an intrusive igneous rock and basalt is an extrusive igneous rock. As an extrusive igneous rock, the magma that formed granite had a long time to cool underground, and therefore consists of larger, visible mineral crystals. Basalt on the other hand, cooled rather rapidly from magma after eruption from a volcano and therefore is aphanitic, with crystals too small to be seen with the naked eye. There is also a difference in chemistry. Granite is considered felsic, with a preponderance of silicate minerals like quartz and orthoclase feldspar. Basalt is considered mafic, with an abundance of heavier minerals like olivine and amphibole, thus making it heavier than granite. These minerals also give basalt a dark color compared to the lighter colored granite.
Granite with larger crystals, basalt with smaller crystals.
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
The will be large in an extrusive granite and fine in an intrusive basalt.
Igneous rocks, such as granite and basalt, often have crystals embedded within them.
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
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.
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
Igneous rocks, such as granite and basalt, often have crystals inside due to their formation from cooling magma.
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.
Crystals in basalt that formed underwater are smaller because they cool faster in the water, resulting in less time for the crystals to grow. On the other hand, crystals in basalt that formed on the ground have more time to grow as they cool more slowly, leading to larger crystal sizes.
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
