Determining the characteristics of the Earth's layers requires conducting experiments, not using x-rays.
Observing properties that require a tool are hardness and carbonate content, contrasting to cleavage and luster.
The mantle is defined by its chemical composition.
i couldn't get the last question i accidentally skipped a page and its like 1 AM as i'm writing this lol
