Obsidian when knapped would have the sharpest cutting tool edge of any igneous rock.
igneous rocks are used for blilding and for long lasting moument.
Many igneous rocks are hard, dense, and durable. People throughout history have used igneous rock for tools and building materials.
Igneous rocks are important to science because scientist need to know about all the different types of things in our world today. The reason also because igneous rocks come from volvanoe and the stuff that comes out of a volcanoe is called LAVA /MAGma!
The main type of energy used to help convert metamorphic rocks into igneous rocks is heat. This heat can come from processes such as magma intrusion, volcanic activity, or tectonic movements, causing the metamorphic rocks to melt and recrystallize into igneous rocks.
Rhyolititcen rocks.
Yes. Obsidian in particular has been used to make tips for arrows and spears.
Igneous rocks are durable and resistant to weathering, making them ideal for tool making and construction. Their hardness and strength also make them suitable for grinding tools and creating sharp edges. Additionally, the abundance of igneous rocks in many regions meant they were readily available for use by ancient civilizations.

Igneous rocks are useful because they provide information about Earth's history, such as how they were formed and the conditions of their formation. They also contain valuable resources like metals and minerals. Additionally, igneous rocks are used in construction materials and as decorative stones.
Extrusive igneous rocks i think are used for carving and awesome things like that!

igneous rocks
The main type of energy used to convert metamorphic rocks into igneous rocks in the rock cycle is heat. The increase in temperature causes the metamorphic rocks to melt and then solidify into igneous rocks.
The Romans made quern stones by shaping them and smoothing them with metal hand tools. They used igneous rocks - rocks is formed through the cooling and solidification of magma or lava. Basalt was the favourite one. When igneous rock was not available, sandstone, quartzite or limestone was used.
