The mantle has less aluminum and silicon than the crust does.
The three main layers of the earth are the Core, Mantle and Crust. The Core is mostly made from iron and nickel, the Crust from oxygen, silicon and aluminum and the mantle silicon,oxygen,iron and magnesium.
The Asthenospheric mantle and the Inner mantle are made up of solid rock and liquid rock.
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.
minerals and such. each layer has different elements. crust: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium mantle: magnesium, silicon, iron, and oxygen outer core: super-heated liquid molten lava, which is mostly made of iron, and nickel inner core: mostly of iron, and small amounts of nickel. with oxygen, silicon, aluminum, and magnesium i hope this all helped
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
The mantle has less aluminum and less silicon than the crust does.
silicon
The mantle is denser than the crust because it contains more iron and magnesium-rich minerals. These minerals have a higher density compared to the minerals found in the crust, such as silica and aluminum.
magnesium and a little bit of aluminum and silicon
Crustal rock is normally less dense than mantle rock.
The mantle layer with more convection is the upper mantle, which has a higher temperature and undergoes vigorous convection currents. In contrast, the lower mantle has less convection due to its higher pressure and lower temperature, leading to slower convective movement.
Continental rock is less dense than mantle rock.
Tectonic plates float on the mantle because they are less dense

An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
