Olivia listed possible processes and materials that form sedimentary rock
1. cementation
2. compaction
3. sediments
4. foliation
5. magma
which numbers should olivia remove from the list? choose the correct answer.
1 and 2
2 and 3
3 and 4
4 and 5

Olivia should remove 4 and 5 from the list since they are not the part of process and materials that are involved  in the formation of sedimentary rocks.

Explanation:

Sedimentary rocks can also be called as derived rocks as their formation is from the pieces of pre-existing rocks. They are the formed by the process of weathering of preexisting rocks, transportation of the weathering products, deposition of the material that is  followed by the process of compaction, and cementation of the sediment that will result in the formation of rock. The last two process can be termed as lithification.

When rocks are nearer to the earth's they are supposed to undergo the process called weathering.

Sediments are those that are deposited layer by layer. They get deposited horizontally. Using compaction process we can reduce the pore space and expel the water contained in the pores.

Hence, Olivia needs to remove the option 4. Foliation and 5. Magma that are not the part of process and materials that are involved  in the formation of sedimentary rocks.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
