Final answer:
Multiple lines of evidence suggest that the Earth was formed about 4.6 billion years ago. All options are correct.
Step-by-step explanation:
Multiple lines of evidence suggest that the Earth was formed about 4.6 billion years ago. These lines of evidence include:
- Moon rocks and asteroids
- Several locations where complete layering of rock formation date from the Cenozoic back to the Pre-Cambrian
- Rocks found in deep ocean trenches and from core earth sampling
- Molten lava from the Earth's core and rocks
These pieces of evidence provide insight into the age of the Earth and its formation. For example, rocks found in deep ocean trenches and from core earth sampling have been dated using radioactive dating methods to determine their age.
Hence, all of the given options are correct.
