Volcanic rock is a type of rock that forms when molten lava from a volcano cools and solidifies, and is most commonly found near active or dormant volcanoes, and it can be found in many different colors, shapes, and sizes, and are made up of various minerals such as quartz, feldspar, olivine, pyroxene, amphibole, and mica. These rocks are usually very hard and durable due to the high temperatures they experience during formation. They often contain gas bubbles which give them their characteristic vesicular texture. Volcanic rocks have many uses in construction materials such as road base material for highways or sidewalks; landscaping materials; aggregate for concrete; roofing tiles; building blocks; monuments; sculptures; jewelry making components; aquarium decorations etc. They also have industrial uses such as grinding wheels for metalworking tools or abrasives for sandblasting operations. In addition to this they are used in the production of cement due to their high silica content which helps bind other ingredients together when heated at high temperatures and are important sources of information about Earth's history since they contain clues about past eruptions and geological events that occurred millions of years ago.
