Sedimentary Rock Formation & Fossils
  1. Weathering breaks rocks into fragments, which are transported to the ocean by rivers. The fragments fall to the bottom of the ocean as sediments.
    1. The sediment particles become squashed (compaction) and are cemented together by mineral. After a very long time, sedimentary rock is formed.
      1. Sedimentary rock changes into metamorphic rock when it comes under heat and pressure. This happens because it gets buried deep underground and comes close to hot molten rock.
        1. The particles in chalk and limestone are rearranged to form marble.
          1. Fossils form in sedimentary rock when:
            1. Organisms fall into sediment.
              1. There is not enough oxygen to cause the organism to decay.
                1. The organism has hard enough parts to leave a caste in the forming rock.
                  1. Water filtering through the rock deposits minerals in the caste.
                  2. Chalk is full of microscopic fossils because of the sediment from which it is made comes from the shells of microscopic sea organisms.
