How much larger is the mantle then the crust?

The mantle is substantially larger than the Earth's crust. The crust varies in thickness, anywhere from 5-70 km, while the mantle measures at about 2900 km. Also, while the crust accounts for less than one percent of the Earth's over all volume, the mantle makes up a hefty 84%.


Why is the geothermal gradient lower than average in subduction zonegeology?

because the oceanic crust lithospher descend into the mantle at the subduction zone .it will be taken to increasing higher temperature as it get deeper


Inside the earth is it solid or liquid?

There are two sections to the core (or centre) of the Earth. The outer core is liquid as it is very hot. The inner core, however is solid because, despite being hotter, the massive pressure of the Earth's weight compresses it into a metal.


What material is the earth's core made of?

The earth is made out of mostly heavy elements that were created in earlier larger fast burning stars that exploded.the earth and everything on it is made from the ash of these previous stars.the current smaller sun is made out of mostly very light elements which it burns to make solar radiant energy and to provide the earths life with energy. Look up proton proton cycle for suns energy process. Cheers.


What percentage of the earths mass does the crust make up?

The Earth's crust is approximately 1.65 % of the total volume of Earth.Volume of sphere = 4/3 * pi * r^3Volume of earth = 4/3 * pi * 6,360^3Volume of earth (km3) = 1.078x1012Crust is on average 35 km thick.Therefore radius of earth without crust = 6,360 - 35 = 6,325 km.Volume of earth (not including crust) = 4/3 * pi * 6,325^3 = 1.06x1012 km3Volume of crust = Total volume of earth - Volume of earth (not including crust).Volume of crust = 1.77x1010 km3Percentage of earth's total volume taken by crust = (1.77x1010 / 1.06x1012) * 100Percentage of earth's total volume taken by crust = 1.641 %

How was the planets mantle formed?

The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.

Why are the crust and upper mantle taken as one layer?

People often confuse the terms 'lithosphere' and 'crust'. The crust is indeed part of the lithosphere, and the lithosphere [minus the crust] is an extension of the mantle.The distinguishing factor between lithospheric (rock-sphere) mantle and the asthenospheric (soft-sphere) mantle is not compositional, but mainly related to temperature and density.At ocean spreading centers, where new lithosphere forms, there is no sharp contrast between the new, warm, thin lithosphere and the upwelling asthenosphere below. In the old, cool, dense lithosphere that makes up ocean basins, the difference between the 'layers' is quite distinguishable.If you look at it from this perspective, the crust is simply coasting atop the lithosphere, getting a free ride. It is the behavior of the mantle, which comprises both the lithosphere and asthenosphere, that controls how plates form, move, and subduct. So yes, the crust is part of the lithosphere, in that it is made up of rocks.Source(s):I'm a geologist/physicist. BLANCHE MARIE PUEBLAS :)


Which layers form earths rigid mobile tectonic plates?

The lithosphere, which includes the crust and upper mantle, forms the rigid outer shell of the Earth's tectonic plates. These plates float on top of the more fluid-like asthenosphere below. The movement of these plates is driven by processes like convection currents in the mantle.

Why is the earth's crust like an egg?

The earth's crust is like an egg because the eath has a mantle (sort of like a shell) and an egg has a shell as well. Try this get a cup get an egg pour vineger and or salt in to the cup then drop the egg in the cup. Wait 2 or 3 days and after those 3 days the egg will feel soft.


Measures taken to check ozone layer depletion?

There are various measures taken. Ban on CFC's is one of them.


What are some measures taken for the preservation of ozone layer?

Some measures that are taken for the preservation of the ozone layer are:Plantation of tressReduction of products containing CFC's like deodorants, spray cans etc.


Is a tree solid?

yes it is


What is evidence in science?

Physical samples of rock extracted (taken) from deep within Earths crust.


What happens when an oceanic and an oceanic plate collide?

since the oceanic crus is thinner than the Continental crust the oceanic crust get submerged and gets destroyed while the continental crust covers the submerged part as being taken over by continental crust....//\@Rtz Z@r...
