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.
Why does Granite take much longer to form than Basalt?
Granite is an intrusive igneous rock formed deep beneath the Earth's surface from the slow cooling of magma. This slow cooling allows larger crystals to form, resulting in the coarse-grained texture of granite. Basalt, on the other hand, is an extrusive igneous rock formed from rapidly cooling lava on the Earth's surface, which prevents large crystals from forming.
Which rock has more silica granite or basalt?
Granite has more silica content than basalt. Granite is a felsic rock with higher silica content, while basalt is a mafic rock with lower silica content.
How does Basalt differ from granite?
Basalt is an igneous rock that is dark in color and has a fine-grained texture, while granite is also an igneous rock but is light in color and typically has a coarse-grained texture. Basalt forms from lava flows on the Earth's surface, while granite forms from the slow cooling of magma below Earth's surface.
Is granite a phaneritic rock?
Yes, granite is a phaneritic rock. Phaneritic rocks have mineral grains that are visible to the naked eye, typically 1mm or larger in size. Granite is composed of minerals such as quartz, feldspar, and mica, and its coarse-grained texture makes it phaneritic.
What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.

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
Is igneous rock granite or basalt?
Both granite ans basalt are types of igneous rock.
How do you differentiate granite from basalt?
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.

Which type of rock contains minerals arranged in crystals and forms when molten rock cools and turns solid?
Igneous rock contains minerals arranged in crystals and forms when molten rock cools and solidifies. Examples include granite and basalt.
Why would granite rock have larger crystals than igneous rocks formed from lava cooled above the earth's surface?
Because crystals in granite had more time to form
Is granite a phaneritic rock?
Yes, granite is a phaneritic rock. Phaneritic rocks have mineral grains that are visible to the naked eye, typically 1mm or larger in size. Granite is composed of minerals such as quartz, feldspar, and mica, and its coarse-grained texture makes it phaneritic.
What are granite and basalt?
Granite is a coarse-grained igneous rock made up of minerals like feldspar, quartz, and mica. Basalt is a fine-grained igneous rock formed from the rapid cooling of lava and is rich in minerals like plagioclase feldspar and pyroxene.
