Three separate process can lead to the lithification of sediments. During Compaction,the weight of accumulating sediment reduces pore space and forces out water from a sediment. Cementation occurs when ions dissolves in a solution precipitate out,forming minerals that hold the grains together.Pressure can lead to Re crystallization, which causes less stable minerals to rearrange crystals into more stable forms.

Explanation:

Compaction-This is a process by which the soil density is increased by removing the air which is present in the soil pores through mechanical action.

This process is used to improve the soil strength.

Cementation-This is the process through minerals are stored into the pores of the soil to increase the fertility of the soil.

Re crystallization-This is a metamorphic process that is obtained by providing pressure and temperature which causes change in mineral composition and rearrange them into a more stable form.

the value of the 4 in the hundreds place is 400 while the value of th e 4 in the tens place is 40

400 is way bigger than 40.
