Question

Which concept describes early Earth as separated into layers by gravity, with each deeper layer denser than the layer above?

a. Centrifugal force
b. Density stratification
c. Seismic theory
d. Tectonic theory
e. Continental drift

Answer 1

Density Stratification

Step-by-step explanation:

Density stratification is a result of gravitational forces and results in the layering of materials as a function of density. The denser (heavier) material is found beneath the lower density (lighter) material.
