helps scientists understand the evolution through different geological periods.
Explain why some organisms become fossils while others do not
Organisms become fossils when they're buried quickly after they die and their remains are gradually replaced by minerals, turning into rock.
Not all organisms become fossils because fossilization is a rare and specific process.
Factors that increase the rate of fossilisation include
rapid burial, hard parts like bones or shells, and suitable environmental conditions
Explain the difference between relative dating and absolute dating and their techniques
Relative Dating: estimates the age of fossils based off of its surroundings
Absolute dating: provides a specific numerical age using scientific techniques based on the decay of radioactive isotopes.
Describe evidence that supports evolution
Fossil Record shows a progression of life forms from simpler to more complex over time.
Embryology Similarities in early development stages across species indicate shared evolutionary history Comparative Anatomy Reveals similarities in structures among different species, suggesting common ancestry.
law of superposition
In an undisturbed sequence of sedimentary rocks, the oldest rocks are at the bottom, and the youngest rocks are at the top. So, the one below is older.
