Can granite form as a lava flow?
No. Granite forms when granitic magma cools deep underground. When granitic magma erupts as lava it cools more quickly and forms a rock called rhyolite.
Are basaltic igneous rocks lower in density than granitic rocks?
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
Is granite plutonic or volcanic?
Granite is plutonic.
What kind of volcanic eruption happens when granite magma is present?
Granitic magma is highly viscous, meaning it has a high resistance to flow. Granitic magma does not reach the surface very often. It cools underground, thus we have granite. If granitic magma actually reaches the surface it would result in a highly explosive eruption.
Is granite and basalt found in volcanoes?
Granite and basalt are both igneous rocks; however, basalt is considered a volcanic rock, and granite is considered a plutonic rock.
Which is volcanic lava rock basaltic or granitic?
The most common type of lava is basaltic. However some lavas may be andesitic or ryolitic. Rhyolite is the extrustive equivalent of granite.
What do basaltic and granitic magmas have in common?
Basalt and Granite are both made from the same magma.
How do scientists determine mantles is denser than the crust?
The mantle is composed of basaltic rock, the crust is composed mostly of granitic rock. Basalt is denser than Granite.
How does a Granite rock and a Gabbro rock differ from each other?
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.
Light-colored igneous rocks with a lower density than basaltic rocks?
Felsic rocks.
What is the difference between granitic igneous rocks and basaltic igneous rocks?
Basalt is an igneous rock with very fine grains. It is dark colored. Granite is a variety of colors: gray, pink, and white. It has coarse grains.
What would happen if a plate made of granite and a plate made of basalt collided?
Basalt is more dense than granite as it contains more iron and magnesium. This means that it is likely that the more dense basaltic plate would be forced under the less dense granitic plate.
What does it mean to have andesitic composition?
Rocks have a composition between that of granite and basalt
Can granite form as a lava flow?
No. Granite forms when granitic magma cools deep underground. When granitic magma erupts as lava it cools more quickly and forms a rock called rhyolite.
Is syenite granitic?
Syenite is not granitic. Quartz is one of the main minerals found in granitic rock. Syenite contains little or no quartz, but otherwise has the same general composition as granite.
Are basaltic igneous rocks lower in density than granitic rocks?
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
Is granite plutonic or volcanic?
