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.
What are dark colored rocks called?
If you are referring to igneous rocks, they are classified as mafic.
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 are dark colored igneous rocks called?
Granitic igneous rocks are light colored rocks of a low density. Granitic magma is thick and stiff and contains a lot of silicon and oxygen. Granitic magma can build up a great deal of pressure, which is released during violent volcanic eruptions.
What rock has a foliated dense rock that has light and dark colored banding?
Gneiss
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
Igneous rocks that are dense and dark-colored are called basaltic rocks. They are formed from magma that is rich in iron and magnesium and poor in silica content.
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
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.

What is dark colored rocks called?
igneous
Dense heavy dark-colored igneous rocks form from what magma?
Basalt froms from basaltic lava is heavy, dark-colored, dense lava. Basaltic lava is dark because it contains high amounts of iron and magnesium.

What property is common to most dark-colored igneous rocks?
Most dark-colored igneous rocks have a high density.

Most dark-colored igneous rocks have a high density.
What colors are basalt rocks come in?
They are usually dark colored and dense. Most common colors are dark grey, dark green, black, and a brownish black. This is a helpful site www.nativetech.org/stone/stonetypes/volcanic.html
