What is the mafic rock that is full of holes and made of dense materials is?
The mafic rock that is full of holes and made of dense materials is basalt. Basalt is formed from lava that has rapid cooling, which traps gas bubbles inside the rock.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
What are the terms felsic and mafic used by geologists to describe?
Geologists use the terms felsic and mafic to describe the compositions of igneous rocks. Felsic rocks are rich in silicon and aluminum, making them lighter in color and less dense. Mafic rocks are richer in magnesium and iron, making them darker in color and denser.
What is an example of a mafic rock?
Basalt is a common example of a mafic rock. It is dark in color, fine-grained, and rich in minerals like pyroxene and olivine. Basalt is formed from the solidification of magma with low silica content, typically from volcanic activity.
Does continental lithosphere contain more mafic rocks than oceanic lithosphere?
No, oceanic lithosphere contains more mafic rocks compared to continental lithosphere. Oceanic lithosphere is mainly composed of basalt, which is a mafic rock, whereas continental lithosphere is composed of a variety of rock types, including granitic rocks which are more felsic in composition.

What is a dark dense rock that is rich in iron and produced by cooling magma?
Mafic igneous rocks, like basalt and gabbro.
Which rock is denser continental or oceanic rock?
The average continental rock is less dense than the average oceanic rock. This is why when an oceanic and continental plate collide, the continental plate does not get subducted. There are varyations within the continental plates however, with some rocks being muck more dense and some being much less dense than the average.
Is granite a mafic rock?
No. Granite is an intrusive felsic rock.

Which kind of magma is more likely form a volcanic rock?
Mafic magma is more likely to form volcanic rock. Mafic magma is rich in magnesium and iron, and tends to have lower viscosity and higher temperatures, allowing it to flow more easily to the surface and form volcanic rocks such as basalt.
Which igneous rock has a dark color?
Mafic
What are the 2 kinds of rock?
Mafic and felsic.

What is a type of mafic phaneritic rock?
Gabbro is a type of mafic phaneritic rock. It is composed mainly of pyroxene, plagioclase feldspar, and often contains minor amounts of amphibole, olivine, or biotite. Gabbro forms from the slow crystallization of mafic magma deep within the Earth's crust.
