Here's a breakdown of the rock types:

* Igneous Rocks: Formed from the cooling and solidification of magma (molten rock) or lava. Basalt is a common igneous rock formed from volcanic eruptions.

* Granite: An igneous rock (specifically, an intrusive igneous rock, meaning it cooled slowly underground).

* Gneiss: A metamorphic rock, formed from the transformation of existing rocks (igneous, sedimentary, or other metamorphic rocks) under intense heat and pressure.

* Marble: A metamorphic rock, formed from the recrystallization of limestone.

* Limestone: A sedimentary rock, formed from the accumulation of organic materials (like shells and skeletons) and chemical precipitation.

* Shale: A sedimentary rock, formed from the compaction of clay, silt, and mud.
