Geologist may determine the density of earth materials by measuring the mass of the object and its volume.
<h3>What is density ?</h3>
The mass of a substance per unit of volume is its density. Density is most frequently represented by the symbol, however Latin letter D may also be used. The formula for density is mass divided by volume
Earth's density is around 5.513 g/cm3 if you average the density throughout the entire globe. However, if you compare the density of the Earth by its layers, you'll notice that it rises continuously from the crust to the core.

By observing how seismic waves are absorbed and refracted, scientist have been able to work out where the properties of the earth change dramatically. our understanding of the internal structures of the earth and the size of its core is based on these observations.
basically:
size of core
structure of the earth I.e. the layers of the earth
and I think the last one is how the internal structure is changing? not sure on the last one but its still a solid guess.
Answer:
weathering
Explanation:
it first weathers then it can erode then be deposited
