The dominant color of the andesite is black with some spots of red and gray.

Andesite is a type of igneous rock that is typically light to dark gray in color. It forms when magma from the Earth's mantle solidifies and cools relatively quickly. Andesite is commonly found in volcanic regions such as the Andes Mountains in South America.
Rhyolite is the most felsic rock out of rhyolite, andesite, and basalt. Felsic rocks have a higher silica content and are associated with continental crust. Rhyolite is typically light in color and has a high silica content, making it more felsic compared to andesite and basalt.
Andesite rock typically has a hardness of around 7 on the Mohs scale, which means it is relatively hard and durable. It is commonly used in construction and landscaping due to its strength and resistance to wear and erosion.
Andesite rock is formed through the cooling and solidification of magma in the Earth's crust. It typically forms in volcanic settings where magma with intermediate composition (between felsic and mafic) cools relatively slowly, allowing for the formation of fine-grained crystals. This results in a rock with a medium to dark gray color and intermediate mineral composition.
Andesite is an intermediate volcanic rock that contains more silica and is lighter in color compared to basalt. Basalt is a fine-grained volcanic rock that is darker in color and forms from rapidly cooling lava at Earth's surface.
No. Andesite is a volcanic rock.
No. Andesite is an extrusive igneous rock.
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
Yes. Andesite is an extrusive igneous rock.
The composition of the rock will determine whether it is a rhyolite or an andesite.
Yes. Andesite is the extrusive equivalent of diorite
Andesite is classified as an extrusive rock and the name of this rock is South American in origin. However, the hardness of this rock is not listed.

No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
