4. what are the two main processes involved in lithification?\nerosion and deposition\nmelting and…

Brief Explanations:

Lithification is the process of turning loose sediments into sedimentary rocks. Cementation involves minerals precipitating and binding sediment grains together, and compaction is the squeezing of sediments under pressure to reduce pore - space. Erosion and deposition are related to the movement and placement of sediments but not lithification. Melting and solidification are for igneous rock formation. Weathering and transportation are about breaking down and moving rocks and sediments respectively, not directly lithification processes.

Answer:

C. Cementation and compaction
