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.
Lava is an example of what kind of rock?
Lava flows in Hawaii are an example of Mafic Lava. Mafic Lava is composed of Basaltic rocks of which tend to have high levels of iron and magnesium.
Where do granite and basalt form?
Granite forms deep underground as felsic magma cools, mostly under continents. Basalt forms at or near the surface as mafic magma cools, typically on oceanic plates.
What kind of igneous rock is mafic and formed deep in the ground?
A mafic igneous rock formed deep within the Earth's crust is typically basalt. Basalt is fine-grained and rich in minerals like pyroxene, olivine, and plagioclase. It commonly forms from the solidification of magma that has originated from the mantle.
How do mafic volcanic rocks get to Earth's surface?
Mafic volcanic rocks reach the Earth's surface through volcanic eruptions. These rocks originate from the mantle and are rich in magnesium and iron. When magma containing mafic composition rises to the surface, it can erupt as lava and form volcanic landforms like shield volcanoes or basalt flows.
Why is basalt classified as an igneous rock?
Basalt is considered igneous because it forms when mafic lava cools at Earth's surface.

Are mafic rocks solely intrusive or extrusive?
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.
What kind of igneous rock is mafic and formed deep in the ground?
A mafic igneous rock formed deep within the Earth's crust is typically basalt. Basalt is fine-grained and rich in minerals like pyroxene, olivine, and plagioclase. It commonly forms from the solidification of magma that has originated from the mantle.
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.
How can you tell that Mount Fuji is a composite volcano rather than a shield volcano?
The volcano is very wide it means that it has mafic magma. The composite volcanoes have mafic magma in them. When the volcano erupts the lava flows down really fast, but hardens really slowly causing the volcano to widen its width size.
How do mafic volcanic rocks get to Earth's surface?
Mafic volcanic rocks reach the Earth's surface through volcanic eruptions. These rocks originate from the mantle and are rich in magnesium and iron. When magma containing mafic composition rises to the surface, it can erupt as lava and form volcanic landforms like shield volcanoes or basalt flows.
Basaltic magma forms what kind of igneous rock?
Mafic igneous rock. ( due to Ferromagnesian minerals).
Name one mafic igneous rock formed when melted rock material cooled near the surface of the earth?
Basalt is a mafic igneous rock formed when melted rock material cools near the surface of the Earth. It is characterized by its dark color and fine-grained texture.
Does gabbro cool above ground or under?
Gabbro is the product of slow cooling of mafic magma below the surface.
