Sedimentary rocks are formed by cementation and compaction. This happens when sediment particles are compressed and fused together over very long periods of time.
Your answer will be sedimentary rocks because there are formed when a rock gets a lot of pressure against other rocks then they compact together forming a sedimentary rock. Also its not Igneous rocks because they are formed when lava flows it cools then gets pressure making a igneous rock remember that sedimentary rocks are like mountains most of their rock was compacted together with heat and pressure making a sedimentary rock and igneous rock is when lava hardens then pressed with a lot of heat and pressure forming a igneous rock. Your answer is sedimentary rock.
