Final answer:
The evidence that supports the claim that it is Earth and not the sky that is turning includes fossils, rock layers, and indications of past geological events.
Step-by-step explanation:
The evidence that indicates that it is Earth and not the sky that is turning includes fossils of ancient sea life on dry land far from oceans, the many layers of rock, and indications of past volcanic eruptions, earthquakes, and erosion shaping Earth's surface.
Fossils: Fossils of ancient sea life found on dry land suggest that the Earth changed over time and that some dry land was once covered by oceans.
Rock layers: The ordering of rock layers allows scientists to trace the history of Earth and life on Earth.
Volcanic eruptions, earthquakes, and erosion: These indicate that Earth's surface has been shaped over time, supporting the idea of an older Earth.
