Yes, andesite can be considered porous, though its porosity varies depending on its specific composition and formation process. It typically contains small gas vesicles formed during volcanic activity, which contribute to its overall porosity. However, compared to other volcanic rocks like pumice, andesite generally has lower porosity. The extent of its porosity can influence its water retention and permeability properties.
Andesite is not any age in particular. Some deposites of andesite may be hundreds of millions of years old. However, since andesite is volcanic, some andesite rocks may only be minutes old.
No. It is volcanic. The plutonic equivalent of andesite is diorite.
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
Andesite is a type of igneous rock that can form both intrusively (inside the Earth's crust) and extrusively (on the Earth's surface). When andesite forms intrusively, it typically cools slowly and can create large crystals.
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .

Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
The composition of the rock will determine whether it is a rhyolite or an andesite.
Andesite is a type of igneous rock that can form both intrusively (inside the Earth's crust) and extrusively (on the Earth's surface). When andesite forms intrusively, it typically cools slowly and can create large crystals.
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
