why is sedimentary rocks important
Answer by Jessica Rubio. Confidence votes 5. The Sedimentary rock is important in the rock cycle because it has a part in the cycle just like Igneous rocks and metamorphic rocks. If there was no Sedimentary rocks, there would be no rock cycle. In order to become a sedimentary rock a rock must be broken down or eroded by weathering. The sediments of the rock then go through the lithification process where they â¦ are cemented and compacted together forming a sedimentary rock. 9 people found this useful.
