How does density change as depth increases within the earth?

Answer 1

The density increases.

Pressure rises with depth; density is equal to mass / volume; as a result, the layers beneath us become increasingly dense.

As depth increases within the Earth, density generally increases. This is due to the increasing pressure from the weight of the overlying materials compressing the layers beneath. Additionally, as depth increases, the materials become more compacted, leading to higher density.
