• heat and pressure
• the cooling of magma
• compaction of sediments
• the melting of rock

Which of the following represents the correct order of the processes responsible for the formation of sedimentary rocks?

• erosion, weathering, compaction, cementation, deposition
• compaction, cementation, deposition, weathering, erosion

• extrusive igneous rocks
• sedimentary rocks
• metamorphic rocks

A student obtains a cup of quartz sand from the beach. A saltwater solution is poured into the sand and allowed to evaporate. The mineral residue from the saltwater solution cements the sand grains together, forming a material that is most similar to

• an extrusive igneous rock
• an intrusive igneous rock 
• a sedimentary rock 
• a metamorphic rock
