Rocks made from lava (magma that has erupted onto the Earth's surface) are called igneous rocks.

There are two main types of igneous rocks, depending on how they are formed:

* Extrusive igneous rocks: These rocks are formed when lava cools and solidifies on the Earth's surface. Examples include basalt, rhyolite, and obsidian.

* Intrusive igneous rocks: These rocks are formed when magma cools and solidifies beneath the Earth's surface. Examples include granite, gabbro, and diorite.

So, if you're looking for rocks made from lava or magma, you're looking for igneous rocks.
