Question

sandstone is a sedimentary rock. which two processes cause sand particles to form sandstone?
cementation and cooling
compaction and cementation
cooling and erosion
erosion and heating

Explanation:

Sedimentary rocks like sandstone form through compaction, which presses sand particles together, and cementation, where minerals act as a "cement" to bind the particles. Cooling is related to igneous rocks, and erosion is a process of wearing - away rather than rock - formation for sandstone. Heating is not directly involved in sandstone formation from sand particles.

Answer:

B. compaction and cementation
