* Granite is a felsic igneous rock. This means it's rich in silica (SiO2) and typically forms deep underground, slowly cooling and crystallizing from magma.

* While granite can be found in areas with volcanic activity, it's not directly erupted from volcanoes. Think of it as being "baked" within the Earth's crust.

* However, granite can be exposed by erosion, and pieces of it can be incorporated into volcanic eruptions, giving the erupted material a granitic composition.

* Basalt is a mafic igneous rock, meaning it's richer in magnesium and iron. It forms from rapidly cooling lava, often during volcanic eruptions.

* Basalt is the most common volcanic rock found on Earth. Think of the dark, dense rock that makes up many volcanic features.

In Summary:

* Basalt is the primary type of rock directly erupted from volcanoes.

* Granite doesn't typically erupt from volcanoes, but it can be exposed by erosion or incorporated into eruptions.
