Answer:
sedimentary (ex: limestone), metamorphic (ex: marble), igneous (ex: granite)
Explanation:
sedimentary, metamorphic, and igneous are the 3 types of rocks formed by the rock cycle. didnt know if you only needed that or examples of each kind so I gave both. also not important but a fun fact igneous means made by fire, metamorphic (think of a butterfly, they go through metamorphosis) this means they change, and sedimentary (rocks pressed together to form a new one often found after events such as erosion, etc). hope this helps :)
