The answer is seafloor spreading
B, provide systematic irrigation.
Answer:
1. Compaction occurs where pressure is placed on loosely packed sediment. The volume of the sediment is reduced and water is squeezed out.
2. Cementation occurs when mineral-bearing water circulates among the grains, hardens, and cements the sediment grains together. This process is most effective when lithifying sand and gravel-sized sediments.
Explanation:
All of the above except "formed from the remains of dead plants."
Metamorphic rock is formed by heat and pressure from any type of rock (igneous or sesimentary) and is part of the rock cycle.
