Different igneous rocks have different silica contents. I could go into loads of detail about mineralogy but what you probably need to know is that magma (as rock is immeasurably viscous as it is solid) containing high Si is more viscous that that with low Si (Silicon being Si). Basalt has low Si, andesite has high Si. Both are extrusive igneous, but form at different plate boundary types.
What else can I help you with?
Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
What this different between acid igneous rock and basic igneous rock?
Acidic igneous rocks have a higher silica content and lower magnesium and iron content compared to basic igneous rocks. Acidic rocks are typically light in color and have a higher viscosity, meaning they are more resistant to flow. Basic rocks, on the other hand, have a lower silica content, higher magnesium and iron content, and are typically dark in color with lower viscosity.
What igneous rock or magma has the lowest silica content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.Read more: Which_igneous_rock_out_of_granite_basalt_andesite_and_peridotite_has_the_lowest_silica_SiO2_content
What type of igneous rock has high amounts of silica?
Igneous rocks with high amounts of silica are classified as felsic rocks. Common examples include granite and rhyolite. These rocks typically have a lighter color and are less dense than mafic rocks, which have lower silica content. The high silica content contributes to their viscosity during magma formation and eruption.
What is the classification of rhyolite?
Felsic extrusive igneous rock. It is the volcanic equivalent of granite.

An igneous rock with a low silica content that flows easily?
Basalt is an igneous rock with low silica content that flows easily due to its low viscosity when molten. It often forms from volcanic eruptions and is found in oceanic crust and volcanic islands. Basalt is dark in color and fine-grained, with a composition of around 45-52% silica.

What is igneous rock color mainly determined by?
An igneous rock's color is mainly determined by its silica content.
An example of an igneous rock low in silica is granite?
Granite is actually high in silica, which is why it is considered a felsic igneous rock. An example of an igneous rock low in silica is basalt, which is mafic in composition and contains less silica than granite.
What type of igneous rock has high amounts of silica?
Igneous rocks with high amounts of silica are classified as felsic rocks. Common examples include granite and rhyolite. These rocks typically have a lighter color and are less dense than mafic rocks, which have lower silica content. The high silica content contributes to their viscosity during magma formation and eruption.
What is An igneous rock with a low silica content that flows easily?
Basalt.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
What is the classification of rhyolite?
Felsic extrusive igneous rock. It is the volcanic equivalent of granite.
How the silica content of molten affects the color of igneous rocks?
The more silica contained in a rock, the lighter in color it will be.
Which igneous rock has the lowest silica content?
Basalt has the lowest silica content among common igneous rocks, with silica accounting for around 45-52% of its composition. This low silica content gives basalt its characteristic dark color and rapid cooling properties.
