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 (squeezing of particles together) and cementation (minerals binding particles). Cooling is related to igneous rocks, erosion is a process of wearing - away, and heating is not directly involved in sandstone formation from sand particles.

Answer:

B. compaction and cementation
