We know that the more force we will aplly to any object, the greater will be its density. i.e., F is directly proportional to density. On the other hand, according to universal law of force of gravitation, F=GMm/r^2. This means that F is inversely proportional to r^2. By this we can say that D is inversely proportional to r^2. On the surface r is greater than on the core or mantle. Since r is always positive, r^2 will be greatest at crust. So, the more the radius the less the density. Thus we can conclude that density is least at crust.

But of the 'solid' earth, then the silica rich parts would probably be the least massive. That would be the sandy bits.
Overall, the most dense part is the centre of the Inner Core, and diminishing as one proceeds towards the earth's surface.

Which rock group makes up least of earths crust?
Just to say: This question refers to rock groups. Not what type of rock.Igneous rocks make up most of the earth's crust.
What is mercury water gold and oxygen from densest to the least dense?
(most dense to least dense) gold, mercury, water, oxygen
Which layer of the atmosphere is the least dense?
Hmm... let me see. Hey, Mom, what's the answer? Oh, that's right. The Exosphere is the answer to this question.
Earth's outermost layer is the?
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
Is the crust much more dense than the earth's center?
The earth's crust is less denser than the mantle.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is more dense.
What is the order of earths layers from less dense to most dense?
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
What is the order of earths layers from most dense to less dense?
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
Which is the least dense?
the crust
Which portion of earths crust is more dense. oceanic or continental?
Oceanic
What is the least dense crust outer core mantle or the inner core?
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
What is the dense part of the earth?
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
What layers contain the least dense materials?
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
Which movement of the Earths crust implies that the continental crust is less dense than the oceanic crust?
Plate tectonic movement and subduction zones.
In which layer of earth would you expect to find the least dense materials?
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
Is it true that earths crust contains most of earths mass?
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
What layer in the Earth is the least dense?
i think the crust
