Pumice makes it a good abrasive for cleaning Nd polishing. Native Americans used obsidian to make Sharp tools. Egyptians used granite for statues. They also used other igneous rocks to build fortresses.
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
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.

Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
Granite is an igneous rock with a coarse-grained texture, formed from the slow cooling of molten magma deep within the Earth's crust. Pumice is also an igneous rock, but with a frothy texture, formed from the rapid cooling of gas-rich lava. Basalt is another igneous rock, but with a fine-grained texture, formed from the cooling of lava on the Earth's surface, typically in volcanic environments.

Basalt and pumice.
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.
Examples of igneous rocks include granite, basalt, and pumice. Granite forms from the slow cooling of magma deep within the Earth's crust, while basalt is associated with volcanic activity and forms from rapidly cooled lava. Pumice is a light-colored and porous rock that is often ejected during explosive volcanic eruptions.

Granite is commonly used in building construction and countertops due to its durability and aesthetic appeal. Basalt is often used as a construction material for roads and railway ballast because of its strength and resistance to weathering. Pumice is used in abrasives, polishes, and horticulture as a lightweight, abrasive material.
Yes, there are many. Granite, basalt, scoria, rhyolite and pumice are some examples.
