Explain the process of fossil formation.

• Fossil formation happens when an organism is eaten by other animals and its remains are scattered across the ground.

• Fossil formation is the result of an organism being frozen in ice and preserved in its original state.

• Fossil formation occurs when an organism is exposed to sunlight and air, causing it to slowly turn into a fossil.

• Fossil formation occurs when an organism is buried by sediment and the organic materials are replaced by minerals over time.

What is the law of superposition and how is it used in paleontology?

• The law of superposition is used in paleontology to determine the relative ages of fossils and rock layers.

• The law of superposition is used in paleontology to analyze the chemical composition of fossils and rock layers.

• The law of superposition is used in paleontology to study the behavior of living organisms.

• The law of superposition is used in paleontology to determine the absolute ages of fossils and rock layers.
