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
