Here are some definitions that might clarify something 🙂
The Neoarchean (/ˌniː.oʊ.ɑrˈkiː.ən/; also spelled Neoarchaean) is a geologic era within the Archaean. It spans the period of time from 2,800 to 2,500 million years ago—the period being defined chronometrically and not referenced to a specific level in a rock section on Earth.
In geology, rock is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals.
Flag dipping refers to the movement of a flag as a signal.
Into, entering or changing form, may also refer to:
Geologically, a fjord or fiord (English pronunciation: /ˈfjɔrd/ or /fiˈɔrd/) is a long, narrow inlet with steep sides or cliffs, created by glacial erosion.
