What else can I help you with?
Is liquid magma less dense or more dense?
Liquid magma is less dense than solid rock because it is a molten mixture of rock, minerals, and gases. When magma rises to the Earth's surface and cools, it solidifies into igneous rock.
Explain why some types of magma form igneous rocks that are dark colored and dense?
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.
What kind of rock forms from magma?
Igneous rocks form from magma as it cools and solidifies. Examples include granite, basalt, and obsidian.
Magma cools and solidifies to form what rocks?
igneous rocks
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.
Are igneous rocks heavy?
Igneous rocks can vary in weight depending on factors like mineral composition and density. Overall, igneous rocks tend to be denser and heavier than sedimentary or metamorphic rocks due to their formation from molten magma that cools and solidifies into a dense mass.
Is liquid magma less dense or more dense?
Liquid magma is less dense than solid rock because it is a molten mixture of rock, minerals, and gases. When magma rises to the Earth's surface and cools, it solidifies into igneous rock.
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?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
What is a dark dense rock that is rich in iron and produced by cooling magma?
Mafic igneous rocks, like basalt and gabbro.
Explain why some types of magma form igneous rocks that are dark colored and dense?
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.
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
When magma is cooled it becomes what?
Cooling and solidifying magma turns into igneous rock.
What is igneous rock formed from magma?
An igneous rock formed from magma is intrusive.
Why some types of magma form igneous rocks that are dark colored and dense.?
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.
Why are some types of magma form igneous rocks that are dark colored dense?
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.
How is the igneous rock changed to sedimentary rock?
Sedimentary rock goes deep in the Earth and reaches magma. It then melts and becomes part of the magma. Since the newly formed magma is less dense than the surrounding rock it is lighter than the surrounding rock and it goes up and cools. It then becomes an Igneous rock.
