What elements make up the lower mantle of the earth?
The Earth's upper mantle is composed of rocks that have higher concentrations of mafic minerals (containing iron and magnesium) and lower in concentrations of the felsic minerals (aluminum and silica) than the rocks of Earth's crust.The concentrations of the above elements therefore mean that the Earth's mantle is composed of a series of minerals that are predominately calcium / iron / magnesium aluminum silicates.Such as:Olivine - (Mg,Fe)2SiO4Pyroxene - X(Si,Al)2O6, where X represents either calcium, sodium, iron or magnesiumSpinel - MgAl2O4Garnet - X3Y2(SiO4)3 where X and Y can be a mixture of aluminum, iron, calcium, manganese or magnesium.In the upper mantle, these minerals form the rocks types Peridotite, Dunite (Olivine-rich Peridotite), and Eclogite.
What makes up earth's mantle?
oxygen, nitrogen, every ****** mineral and more on the periodic table...take chemistry
How much of the Earth's outermost 10 miles is composed of sedimentary rocks?
Sedimentary rocks account for about 5 percent of the Earth's outermost 10 kilometers. These rocks cover 75 percent of the Earth's continental area.
Crust mantle and core of mars?
Crust and Surface: Mars' surface is composed mostly of iron-rich basaltic rock (an igneous rock). Mars has a thin crust, similar to Earth's.Mantle: Silicate rock, probably hotter than the Earth's mantle at corresponding depths.Core: The core is made of iron and sulphides and has a radius of 800-1,500 miles (1,300-2,400 km).

What is the depth to the inner core of the Earth?
The Earth's outer core is a molten layer primarily composed of iron and nickel. Its outer boundary lies 2,890 kilometers beneath Earth's surface.
What kind of eruptions and speed of flow do high silica and low silica magmas have when they erupt as lava?
For eruptions it is explosive and for speed of flow it is 6 miles per hour. When the eruption as lava is 18 miles per hour.

Summary of Lines composed a few miles above Tintern Abbey?
The poem entitled Lines Composed a Few Miles Above Tintern Abbey was written of 1798. Its summary is all about a man who had a spiritual relationship with nature and that this environment helped him become a better person.
What verse in Lines Composed a Few Miles Above Tintern Abbey is Not strict blank verse?

Earth's crust is a thin layer made of?
Earth's crust is made of sedimentary, metamorphic, and igneous rock. The continental crust is composed primarily of granitic rock and can be up to 45 miles thick. The oceanic crust is composed primarily of basaltic rock and can be up to 6 miles thick.
Are facts about earths mantle?
The mantle can be subdivided into the upper and lower mantle.The uppermost part of the upper mantle is part of the lithosphere, and is sold and rigid. The lower part of the upper mantle is partially molten, and hence can flow.The lower mantle is solid, but behaves in a plastic fashion, much like blu-tack.The mantle is predominantly composed of an ultramafic rock called peridotite.Further Detail:The Earth's mantle is the largest layer of the Earth by volume accounting for around 84% of the Earth. It is approximately 2885 kilometers thick.The Earth's mantle is composed of rocks that have higher concentrations of mafic minerals (containing iron and magnesium) and lower in concentrations of the felsic minerals (aluminum and silica) than the rocks of Earth's crust.The concentrations of the above elements therefore mean that the Earth's mantle is composed of a series of minerals that are predominately calcium / iron / magnesium aluminum silicates.Such as:Olivine - (Mg,Fe)2SiO4Pyroxene - X(Si,Al)2O6, where X represents either calcium, sodium, iron or magnesiumSpinel - MgAl2O4Garnet - X3Y2(SiO4)3 where X and Y can be a mixture of aluminum, iron, calcium, manganese or magnesium.At depths shallower than approximately 460 km, these minerals form the rocks types Peridotite, Dunite (Olivine-rich Peridotite), and Eclogite.At depths greater than 410 km Olivine becomes unstable and is replaced by a number of different mineral forms known as poly-morphs which are stable at higher pressures. These include Wadsleyite which forms at depths between 410 and 520 km and Ringwoodite which forms between 520 and 600 km deep.These depths are based on a number of seismic dicontinuities at the depths of 410 km (thought to mark the transition from Olivine to Wadsleyite) and at 520 km (thought to mark the transition from Wadsleyite to Ringwoodite) respectively.At depths greater than around 650 km these upper mantle minerals start to become unstable due to the increased pressure and the minerals below this take the structure of the minerals Perovskite and Ferropericlase although with differing chemical compositions and it is this seismic discontinuity at 650 km depth that marks the transition to the lower mantle.Its heat comes from left over radiation from the Earth's creation.It is more denser than the crust. notIt contains more iron than silica.It is 1800 miles thick and makes up more than two thirds of earts mass
What is the largest state in the US in driving miles from east to west?
Hawaii is composed of 132 islands, reefs and shoals that extend for over 1,500 miles. Alaska comes in second at just 1,480 miles east to west.
What is the thickness of the outer?
The Earth's outer core is about 2,266 kilometers, or 1,408 miles thick. It is composed of iron and nickel and is liquid.
Would minerals in a rock buried 2 m beneath the earths surface be affected by pressure?
No only 2 miles deep
What type antifreeze goes in Lincoln ls v6 2000 model?
green or red... avoid the one with silica... silica is for desperate people who try to revive the rolling trash to get some miles out of it... ========================================================= The 2000 Lincoln LS came from the factory with a 50 / 50 mix of distilled water and GREEN color antifreeze ( meeting Ford specification ESE-M97B44-A ) Helpfull
Facts about the earths mantel?
Earthâ??s mantle is the layer underneath the crust. It is composed of silicates and is nearly 2 thousand miles thick.

Though Miles Davis was the first to record it and is often credited as the composer, but it was supposedly composed by Eddie Vinston.
