How are basalt and granite diffrerent in their origin texture and mineral composition How are the similar?
Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.
How is basalt different from gabbro?
Basalt and gabbro are both igneous rocks, with major differences in grain size and where they form. Basalt has fine-grained crystals and forms from lava flows on the Earth's surface, while gabbro has coarse-grained crystals and forms from magma cooling beneath the Earth's surface.
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.
How does Basalt differ from granite?
Basalt is an extrusive, mafic igneous rock, which means that it solidifies from lava at or near the surface, and is composed partly of iron and magnesium minerals. Granite is an intrusive felsic igneous rock, meaning that it solidifies from magma below the surface, and is relatively high in minerals containing silicon and aluminum. Basalt has a higher specific gravity than granite, and is also darker than granite. Basalt may have visible air pockets, frozen in place when it solidified from lava. Granite will not exhibit this characteristic. Basalt has mineral crystals that are not visible with the naked eye. Granite has visible mineral crystals.
What are two igneous rocks formed from slow cooling magma?
Two igneous rocks formed from slow cooling magma are granite and diorite. Granite has a coarse-grained texture due to the slow cooling process, while diorite is a medium- to coarse-grained rock with a speckled appearance.
What kind of rocks make up the most of the igneous rocks?
Basalt and granite are the most common types of rocks that make up igneous rocks. Basalt is a fine-grained volcanic rock, while granite is a coarse-grained intrusive rock.
What core is made basalt and granite?
The Earth's core is primarily composed of iron and nickel, while basalt and granite are found in the Earth's crust and upper mantle. Basalt is a dark, fine-grained igneous rock, while granite is a light-colored, coarse-grained rock.
What difference between granite and basalt rocks?
Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica, while basalt is a fine-grained igneous rock composed mainly of iron and magnesium-rich minerals. Granite is lighter in color and has visible grains, while basalt is typically dark in color and has a smoother texture. Additionally, granite forms through slow cooling underground, while basalt forms through rapid cooling at or near the Earth's surface.

Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
Compare granite and diorite?
Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica, while diorite is also coarse-grained but consists mainly of plagioclase feldspar and amphibole. Granite is typically light in color, while diorite is typically darker. Both rocks are used in construction and as decorative stones.
What is the difference between granite and dolerite?
Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. Dolerite, also known as diabase, is a medium- to coarse-grained intrusive igneous rock with a composition similar to basalt. One key difference is that granite forms at shallow depths within the Earth's crust, while dolerite forms at deeper levels.
What is the bedrock that makes up the bulk of the continents?
The bedrock that makes up the bulk of the continents is primarily composed of granite and basalt. Granite is a coarse-grained igneous rock that forms through the slow cooling of magma beneath the Earth's surface, while basalt is a fine-grained igneous rock that forms from the rapid cooling of lava at the Earth's surface. These rocks are commonly found in the continental crust and make up a significant portion of the Earth's landmass.
