Sedimentary Rocks

What factors can lead to the formation of a sedimentary rock?

• melting and solidification

• extreme heat and pressure

• compaction and cementation

Rock made of layers of compressed sediments

• metamorphic rock
• igneous rock
• sedimentary rock
• school house rock

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

• weathering
• sediment
• erosion
• cememtation

Small pebbles, pieces of other rock, and sand are called?

• weathering
• sediment

What characteristic to sedimentary rocks often have?

• weather patterns
• tiny crystals
• striped layers
• glassy surfaces

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
