Identify and describe the two main methods for measuring the age of earth and its parts.

my teacher would say no s

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.

for a different answer set the answer would be because the oxygen in the water had depleted (apex)

idk about that one.
