Just look at the molars: One is obviously for eating meat, as the jaws in the front are sharp and can easily shred meat. One is for chewing plants, as it's molars are flat.
Answer:
Sediments compact and cement together.
Explanation:
Generally, rocks are of three main types viz: Igneous, sedimentary and metarmophic rocks. Based on the question, the sedimentary rocks are that group of rocks formed by the coming together of sediments.
Sedimentary rocks can be formed in the following steps;
1. Rocks that have existed before undergoes weathering i.e. are broken down into smaller particles called sediments.
2. These sediments are then transported by currents e.g water
3. Deposited sediments accumulate and gathered round.
4. The accumulated sediments become compacted i.e. squashed and cemented i.e. stick together to form the sedimentary rock, in a process collectively lithification.
Hence, compaction and cementation (lithification) are the next steps in the process of sedimentary rocks formation after deposition.
