They are all Igneous rocks.
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
Igneous rocks
Basalt and pumice.
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.

Granite is an igneous rock that is coarse-grained and mainly composed of quartz, feldspar, and mica. Scoria and pumice are volcanic rocks with vesicular textures due to gas bubbles. Obsidian is a natural glass formed from rapidly cooling lava without crystallization.
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.

These materials belong to the category of rocks or stones, commonly used in construction and architecture. Granite, pumice, obsidian, limestone, sandstone, and marble each have distinct properties that make them suitable for different applications such as countertops, flooring, or sculptures.
Neither. Both pumice and obsidian are igneous.
Granite has large mineral grains compared to basalt, obsidian, and pumice. It is an intrusive igneous rock formed from the slow crystallization of magma beneath the Earth's surface, allowing large crystals to develop. In contrast, basalt has smaller grains due to its rapid cooling, while obsidian is volcanic glass with no visible grains, and pumice is a light, porous rock with small, frothy bubbles.
