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.
No, His data is not controlled. Being he let the younger siblings answer and they are not his classmates.
Answer:
D. Artificial Selection.
Explanation:
Normal people can't breed cats by modifying their DNA, so options b and c are eliminated. Breeding cats for specific traits is not natural, so it is not choice a, either. Instead, selective breeding is d. artificial selection.
Hope this helps!
