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.
Just to say: This question refers to rock groups. Not what type of rock.Igneous rocks make up most of the earth's crust.
(most dense to least dense) gold, mercury, water, oxygen
Hmm... let me see. Hey, Mom, what's the answer? Oh, that's right. The Exosphere is the answer to this question.
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.
The earth's crust is less denser than the mantle.
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
The Earth's crust is the least dense layer. It is made up of rocks like granite and basalt and is relatively thin compared to the other layers of the Earth.
Helium is the least dense element at normal conditions.
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
The Earth's compositional layers in order of increasing density are the crust, mantle, outer core, and inner core. The crust is the least dense layer, while the inner core is the most dense layer.
Oceanic
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
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
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
Plate tectonic movement and subduction zones.
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
i think the crust
