  • What is fossilization
    Fosalgabun refers to remains or tracts of living things from the past preserved in rock.
  • What is the purpose of fossilization
    To study and learn about life from the past.
  • What conditions are required for the formation of fossils?
    • Rapid burial of the organism to prevent decomposition
    • Lack of disturbance by erosion or other factors
    • Mineralization where organic material is replaced by minerals to preserve original structure
  • What is the first stage of fossilization?
    Burial, where the organism must be quickly buried.
  • What happens during the mineralization stage of fossilization?

    Organic parts of the organism are replaced by minerals to preserve its shape.
  • How does compression affect fossils during fossilization?
    Compression causes the weight of layers to squash and distort the fossil.
  • What is the final stage of fossilization?
    Exposure, where the fossil can be uncovered at the surface.
  • What are the stages of fossilization?
    1. Burial: Organism must be quickly buried.
    2. Mineralization: Organic parts are replaced by minerals.
    3. Compression: Weight of layers squashes and distorts the fossil.
    4. Exposure: Fossil can be uncovered at the surface.
