Sure! Here are two options: Igneous rocks and Sedimentary rocks.
Igneous rocks are formed from cooled and solidified magma or lava. They have a crystalline structure and can be either intrusive (formed inside the Earth) or extrusive (formed on the surface).
Sedimentary rocks, on the other hand, are formed from the accumulation and compression of mineral and organic particles over time. They often have a layered appearance and can contain fossils.
In summary, igneous rocks are formed from molten material, while sedimentary rocks come from sediments compacted together.
