Question

fossils provide evidence of what? (there are two correct answers)
evolution
pangaea
radiometric dating
superposition

Explanation:

• Evolution: Fossils show the progression of species over time. For example, transitional fossils like Archaeopteryx (showing features of both reptiles and birds) support the theory of evolution.
• Pangaea: Fossils of the same species (e.g., Glossopteris plant fossils) have been found on different continents. This distribution is consistent with the idea that the continents were once joined together as Pangaea.
• Radiometric dating: This is a method (using radioactive decay) to date rocks and fossils, not something that fossils themselves provide evidence of.
• Superposition: This is a principle in geology about the order of rock layers (younger layers on top of older ones). Fossils can be used in the context of superposition (to date layers), but fossils don't provide evidence of the principle of superposition itself.

Answer:

Evolution, Pangaea
