The scientific term for rocks formed from lava is "igneous rocks." These rocks are created when molten lava cools and solidifies, either on the Earth's surface as extrusive igneous rocks, such as basalt, or beneath the surface as intrusive igneous rocks, such as granite.

These rocks are created when magma cools and solidifies, either beneath the Earth's surface as intrusive (or plutonic) rocks or on the surface as extrusive (or volcanic) rocks.

What are rocks changed by intense pressure and heat become new rocks called?

Rocks changed by intense pressure and heat become new rocks called metamorphic rocks. These rocks form when existing rocks undergo changes in texture and mineral composition due to high temperatures and pressures. Examples of metamorphic rocks include marble, slate, and gneiss.


Are pumice stones and lava rock comparable?

Not all lava rock is pumice. Lava rock is a term used synonymously with pumice by some material suppliers.

Only lava has a density less than that of water, allowing it to float.
