Mafic and ultramafic magmas are high in dark, heavy minerals like pyroxene, amphibole, and olivine, which contribute to an igneous rock being dark in color with a higher specific gravity than felsic and intermediate magmas and rocks.

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.
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 kind of rock forms from magma?
igneous rock
Is liquid magma less dense or more dense?
Liquid magma is more dense than the solid material around it.
Where do all igneous rocks come from?
All igneous rock is the product of hardened magma from the upper mantle, except for igneous rock formed from extraterrestrial impacts.
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.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
basaltic
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.
How is an igneous rock created?
Igneous rocks are created when magma cools into a solid state.
What are large-grained light-colored rocks that form deep inside earth composed of what type of magma?
Igneous

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 is a dark dense rock that is rich in iron and produced by cooling magma?
Mafic igneous rocks, like basalt and gabbro.
How is magma and igneous rocks related?
Magma is molten rock, and igneous rock is cooled magma.
How does magma from igneous rock?
magma cools to form igneous rock
What does magma have to do with igneous rocks?
Igneous rocks are formed by cooling magma.
