The process by which running water, wind, or ice carry away bits of broken-up rock

• weathering
• sediment
• erosion
• cememtation

Which formation process do most sedimentary rocks follow?

• cementation, compaction, deposition, erosion

• erosion, compaction, cementation, deposition

• erosion, deposition, compaction, cementation

Which best describes deposition?

• sediment pressing together

• dissolved minerals crystallize and glue particles together

• particles settle as loosely packed sediment

• running water or wind carry away fragments of rock

Which process best describes compaction?

• particles are squeezed together under pressure

• particles glue together as minerals harden

• sediment settles

How are these layers formed in sandstone?

• melting and solidification

• compaction and cementation

• evaporation and precipitation

• extreme heat and pressure

Compaction is

• When slowing water lays down sediments to form beds

• Squeezing of sediment grains together by the weight of sediments above

• Precipitation of minerals that "glue" the sediment grains together

• When tectonic plate movement raises buried rocks up to the surface
