Why is granite less dense than other rocks in earths mantle?
Because its less dense
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
How are Ocean floor rocks are different from continental rocks?
Oceanic crust is composed primarily of the dense volcanic rock basalt. Continental crust is composed primarily of the intrusive igneous rock granite, less dense than basalt.
Continents float on the Earth's mantle because continental rocks are than sea floor rocks?
lighter continental rock (mainly granite) is less dense than mantle material.continental rock is also less dense than oceanic crust (basalt) but sea floor rocks are not the same thing as mantle material.granite = 2.7 g/cm3basalt = 3.0 g/cm3
Are rocks changed by metamorphism less dense?
That depends on the rock and the type of metamorphism is underwent. Some rocks become more dense, some become less.
Are rocks that are changed by metamorphism more porous or less?
Than?? Marble certainly isn't porous.
Why is granite less dense than other rocks in earths mantle?
Because its less dense
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Light colored igneous rocks are less what than dark igneous rocks?
basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter
What is the contenental crust made up of?
less dense rocks such as granite.
What kinds of rocks are changed by weathering?
All rocks are changed, but it depends on the density. A smooth, hard volcanic rock may take a while to weather because it has less friction, but a bumpy less dense rock may weather faster. However, all rocks wear down by means such as human touching, water, wind, or friction with other rocks. For example in tourist caves some rocks have become smooth from the human touch repeated over and over.
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt
Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
How does the density of a light colored rock differ from the density of dark colored rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
