Answer 1

Rocks are constantly eroded by weather and broken down into smaller pieces over time. This makes it difficult for scientists to locate the oldest rocks on Earth as they may have been weathered away or fragmented into smaller pieces. Additionally, lava flow from volcanoes can bury the old rocks, further complicating their discovery. The idea that the oldest rocks can only be found at the Earth's inner core is incorrect as the Earth's inner core is composed mainly of molten iron and nickel, not rocks.
