What else can I help you with?
Three main layers thay make up earth are?
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.
What are the Asthenospheric mantle and the Inner Mantle are made up of?
The Asthenospheric mantle and the Inner mantle are made up of solid rock and liquid rock.
What part of the earths mantle that flows and moves the plates of the earth?
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.
What layers form the tectonic plates?
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
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.
The mantle has less aluminum and less what than the crust does?
The mantle has less aluminum and less silicon than the crust does.
The mantle has less aluminum and less than the crust does.?
silicon
The mantle is denser than the crust because it contains more what?
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.
What makes up the mantle?
magnesium and a little bit of aluminum and silicon
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Mantle layer with more convection Mantle layer with less convection?
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.
Continents float on the Earth's mantle because continental rocks are 'blank' than mantle rock.?
Continental rock is less dense than mantle rock.
Do the plates float on the mantle?
Tectonic plates float on the mantle because they are less dense
Why do the plates float on the mantle?
Tectonic plates float on the mantle because they are less dense
What are the layers of the Earth in order starting at the outermost layer and going inward Core Mantle layer with more convection Moho barrier Mantle layer with less convection?
1st-moho barrier2nd-mantle layer with more convection3rd-mantle layer with less convection4th-core
What layer is made of magnesium and smaller amounts of aluminum and silicon?
earths mantle is made of silicon,iron,aluminum,calcium,sodium,potassium,magnesium,and mostly oxygen
Why is an aluminum nail less dense than the actual element?
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.
