Which type of rock forms from cooling lava or magma?

Explanation:
Igneous rocks come from molten rock that cools and solidifies. When magma cools underground, it forms intrusive igneous rocks with larger crystals; when lava erupts and quickly cools on the surface, it forms extrusive igneous rocks with tiny crystals or a glassy texture. Sedimentary rocks form from sediments that are deposited and cemented over time, while metamorphic rocks arise when existing rocks are altered by heat and pressure, without melting. Quartzite is an example of a metamorphic rock formed from sandstone under heat and pressure. So, rocks formed from cooling lava or magma are igneous.
