Igneous and Sedimentary Rocks

Sedimentary rocks form from the _________________ and _______________________ of sediments

• cooling and crystallizing

• compaction and cementation

• heating and pressure

A clastic sedimentary rock with large pieces of rock in it is called:

• chemical

• organic

• conglomerate

• igneous

Chemical sedimentary rock can form as a result of

• Eruptions

• Cementation

• Metamorphism

• Evaporation

Sedimentary rocks are

• formed form already existing rocks that are weathered,

  eroded, compacted and cemented together

• cooled on the surface of the Earth from lava

• formed below Earth's surface as magma

• formed from great heat and pressure
